40 years ago a personal computer cost around $500k in todays money and was accessible only to large corporations. Today, as the clich goes, that kind of processing power is available to most people in an affordable mobile phone. Quantum computing, however, is a different matter. Quantum computers are stuck in the 1950s: there arent many of them, they cost tens of millions of dollars, and they take up entire rooms.

One of todays very rare and very costly quantum machines is being developed by D-Wave Systems Inc., a company whose CEO happens to be Vern Brownell, a former CTO of Goldman Sachs. Goldman is one of several lead investors in D-Wave, which its described as having a head start in the field. While most quantum computing rivals are still in their infancy, D-Wave has already been using its system for machine learning. Competitors are eyeing the same plot: 1QB Information Technology Systems Inc (1QBit), a Vancouver-based quantum computing, counts derivatives exchange CME Group among its investors. An RBS banker who led 1QBits 2015 finance round toldBloombergquantum computing is perfect for the data-rich time-sensitive world of financial markets.

Interestingly, therefore, an opportunity has arisen to write machine learning algorithms for quantum computers and then implement them using D-Wave 2000Q, the companys first commercially available quantum computer. Training on the system will be made available too.

The quantum machine learning program is being run by the Creative Destruction Lab (CDL), a seed funding program for science-based companies based in Toronto. Last month, it invited applications for 40 places on an initiative intended to develop and sponsor a wave of quantum machine learning start-ups. The next (and last) round of applications closes on Monday July 24th.

Daniel Mulet, associate director of machine learning at CDL says theyve already received 42 applications, around 10% of which are biased towards financial services. Some are very early stage and have been submitted by students, but others are companies that have already been launched, says Mulet. - Theres one thats working with a hedge fund looking for patterns with trading data.

Traditional computers use binary code to solve problems: a bit can be a 1 or a 0. Quantum computers use qubits: a bit can be a 1 or a 0 or a 1 AND a 0 As Bloomberg points out, therefore, if you have two qubits you can have four potential states: 00, 01, 10, and 11. Moreover, the number of states a quantum computer can take into consideration is2 raised to the power of the number of qubits: if you had a 50-qubit universal quantum computer, you could explore1.125 quadrillion states simultaneously.

Quantum computers are able to process much larger quantities of data much faster, says Mulet. Its our belief that these new quantum hardware platforms built by D-Wave or IQB will be used for various machine learning applications in the next few years. When that happens, we want to be ready to leverage that. One day all Bloomberg terminals will be run on quantum computers.

Its not hard to see why Goldman is interested.

If youre interested too and want to apply, you have 39 days to polish your application. As a further lure to candidates, those selected will be mentored by the likes of William Tunstall-Pedoe, a Cambridge AI entrepreneur, and Barney Pell, chief strategy officer at San Francisco-based Loco-Mobi (which is applying AI to parking your car).Those graduating from the program, which begins in September, will receive $80k in funding in return for 8% of the equity in their company.

Mulet says ideal applicants will have a Masters or PhD in a quantitative subject, and be proficient in programming in Python and the use of Tensor Flow, Googles open source library for machine learning.

Accenture, 1QBit partner for drug discovery through quantum computing – ZDNet

Posted: at 9:44 pm

Accenture has partnered with quantum software startup 1QBit to develop a quantum-enabled molecular comparison application for US multinational biotechnology firm Biogen.

The application is expected to improve advanced molecular design to speed up drug discovery for complex neurological conditions such as multiple sclerosis, Alzheimer's, and Parkinson's.

Researchers at Accenture Labs worked with 1QBit to create the new application, which enhances Biogen's existing molecule comparison method through quantum computing.

Molecular comparison is a crucial part of early-phase drug design and discovery, Accenture explained, and involves intensive computational methods to review molecule matches and predict the positive effects of a therapy or drug while reducing negative side effects.

As quantum computing has the potential to find the answer to complex problems millions of times faster than classical computing by leveraging the properties of quantum physics, Accenture said the new application provides insights into the molecular comparison process as well as much deeper contextual information about how, where, and why molecules match.

This is expected to enable scientists and researchers to analyse large collections of molecules more quickly and cost effectively.

"At Biogen, we're always looking to harness cutting-edge technologies that push the boundaries of traditional pharmaceutical research to discover new treatments and cures for complex neuroinflammatory and neurodegenerative conditions," Govinda Bhisetti, head of Computational Chemistry at Biogen, said.

"Collaborating with researchers at Accenture Labs and 1QBit made it possible to rapidly pilot and deploy a quantum-enabled application that has the potential to enable us to bring medicines to people faster."

Accenture Labs said it has identified more than 150 use cases with clients where quantum computing would be relevant, and is working with clients across multiple industries to prepare for the arrival of mainstream quantum computing.

Also on Friday, Accenture expanded its partnership with SAP to include working with SAP Leonardo, the ERP giant's digital innovation system that combines differentiating software capabilities in machine learning, the Internet of Things (IoT), big data, analytics, and blockchain on its SAP Cloud Platform.

Accenture will be integrating more than 50 of its enterprise analytics applications with SAP Leonardo, spanning finance and accounting, supply chain, procurement, human capital management, and sales and customer service.

"Today, we're at an incredible tipping point," said Pierre Nanterme, Accenture chairman and CEO. "We're face to face with an era of tremendous business transformation where the fundamental rules of how we create value are being rewritten. What we're announcing today is a bold step in defining the rules for the intelligent enterprise."

The companies first began working together 18 months ago on SAP S/4HANA, aiming to simplify and fast-track the "digital journeys" of its clients. SAP and Accenture had partnered back in 2010 for Business ByDesign and in 2014 expanded their global alliance through an agreement to offer cloud-based offerings designed for industry-specific and technology-enabled operations.

Consortium Applies Quantum Computing to Drug Discovery for Neurological Diseases – Drug Discovery & Development

Posted: at 9:44 pm

Accentureand quantum software firm1QBitcollaborated with Biogen to develop a first-of-its-kindquantum-enabled molecular comparison applicationthat could significantly improve advanced molecular design to speed up drug discovery for complex neurological conditions such as multiple sclerosis, Alzheimers, Parkinsons and Lou Gehrigs Disease.

Researchers atAccenture Labscollaborated with 1QBit to create the new application which enhances Biogens existing molecule comparison method with quantum capabilities. Molecular comparison is a crucial part of early-phase drug design and discovery, and involves intensive computational methods to review molecule matches and predict the positive effects of a therapy or drug while reducing negative side effects.

By leveraging quantum computing a computing paradigm that has the potential to find the answer to complex business problems millions of times faster than classical computing by leveraging the properties of quantum physics the new application provides novel insights into the molecular comparison process as well as much deeper contextual information about how, where and why molecules match. This is expected to enable scientists and researchers to analyze large collections of molecules more quickly and cost effectively.

At Biogen, were always looking to harness cutting-edge technologies that push the boundaries of traditional pharmaceutical research to discover new treatments and cures for complex neuroinflammatory and neurodegenerative conditions, said Govinda Bhisetti, Head of Computational Chemistry, Biogen. Collaborating with researchers at Accenture Labs and 1QBit made it possible to rapidly pilot and deploy a quantum-enabled application that has the potential to enable us to bring medicines to people faster.

In just over two months, Accenture Labs, Biogen and 1QBit progressed from an exploratory conversation about quantum business experimentation to an enterprise-ready, quantum-enabled application that generates molecular comparison results with deeper insights about shared traits. As quantum computers become more readily available, it will become easier for pharmaceutical companies to identify and develop new medicines for a wide range of diseases and conditions, saidJeff Elton, Ph.D., managing director, Accenture Strategy, Life Sciences.

Accenture Labs is focused on helping clients across multiple industries prepare for the arrival of mainstream quantum computing, which offers great potential to solve challenges in entirely new ways through quantum-enabled optimization, sampling, and machine learning algorithms, said Marc Carrel-Billiard, senior managing director, Accenture Labs. Through our collaboration with Biogen, 1QBit and our colleagues in the AccentureLife Sciences industry group, we have achieved a breakthrough that confirms the speed and accuracy of the quantum-enabled method for molecular comparison and takes another significant step toward improving the pharmaceutical industrys drug discovery and design process to help deliver better patient and economic outcomes more efficiently.

According to theAccenture Technology Vision 2017companion survey of more than 5,400 business and IT executives, 40 percent of respondents are taking proactive steps to prepare for quantum computing, with 36 percent planning to invest in quantum capabilities in the next two years.

Playing a key role in Accentures overallInnovation Architecture, Accenture Labs helps clients harness emerging technologies to change the way the world works and lives. Given the potential for quantum computing to disrupt the computing landscape in the next two to five years, helping clients identify opportunities and begin working with quantum computing to stay ahead of the broader introduction and deployment of associated technologies is a key focus area. Accenture Labs has already identified more than 150 use cases with clients from portfolio optimization in the financial services sector to production scheduling in manufacturing where quantum computing would be relevant.

Chinese satellite breaks a quantum physics record, beams entangled photons from space to Earth – Los Angeles Times

Posted: at 9:43 pm

Chinese scientists have just set a record in quantum physics.

For the first time, pairs of entangled photons have been beamed from a satellite in orbit to two receiving stations almost 1,500 miles away on on Earth.

At the same time, the researchers were able to deliberately separate the entangled photon pairs along a greater distance than has ever been recorded.

The experiment, described Thursday in the journal Science, represents the first measurable proof of an idea that has long been theorized but never tested, experts said.

This is the first time you have a quantum channel between a satellite and the ground that you can actually use, said Norbert Ltkenhaus, a professor at the Institute for Quantum Computing at the University of Waterloo in Canada who was not involved in the new work. People have been talking about doing it for many, many years, but these guys actually did it.

Keep reading to learn what this new work means, and why it matters.

Great question. For starters, a photon is a tiny particle of light. In fact, it's the smallest unit that light can be broken into. It has no mass and no charge.

Entangled photons are a pair of photons whose properties are linked, and remain that way no matter how far apart they get.

If you make a measurement on one of the photons, you get a perfectly correlated outcome on the other member of the pair, Ltkenhaus said.

And that will hold true not matter how many times you look at them.

One measurement alone doesnt tell you they are entangled, you need to repeat it many times, he said. With entangled photons no matter what you measure, or how many times you measure, or which side of the pair you measure, you always get perfect correlation.

Another great question. This one is more difficult to answer.

Scientists have not been able to explain why entanglement occurs. All they know is that it exists.

Einstein referred to the phenomena of entanglement as spooky action at a distance. Others have said it is kind of like the physics version of voodoo.

They built a special satellite to do it.

The spacecraft, nicknamed Micius after a famous 5th century Chinese scientist, launched in August 2016.

It is loaded with a special crystal that can split a single incoming photon into two daughter photons with joint properties. For this experiment, instruments on the satellite separated the entangled photons and sent them to different receiving stations on Earth.

To do this, Micius had to aim at its targets with an amazing degree of precision, said Jian-Wei Pan, a physicist at the University of Science and Technology of China who led the work.

Its the equivalent of clearly seeing a human hair at a distance of 900 feet away, he said.

It is extreme. And, experts say, challenging.

Designing, launching and operating a satellite with this capability is no easy feat, Ltkenhaus said. I see this as a great engineering triumph.

But, as the study demonstrates, using a satellite to send beams of entangled photons to Earth is a better strategy than using optical fibers to distribute them.

The greatest distance scientists have been able to separate entangled photons using optical fibers is 62 miles. By sending the entangled photons through space, Pan and his team were able to separate entangled photons by more than 620 miles.

Not immediately, but eventually, it probably will.

For example, distributing entangled photons over large distances could be used to establish unhackable communications via whats known as quantum cryptography.

This application relies on another strange aspect of quantum mechanics namely that the simple act of observing a photon disturbs it and causes it to change its orientation.

Scientists have already been able to establish secure, quantum channels using fiber optics, but there is a limit to how far those can stretch.

Using the space-based quantum channel, the authors have shown it is possible to significantly extend the distance over which one can perform such a secure communication, said Jrgen Volz, a physicist at the Vienna Center for Quantum Science and Technology who was not involved in the work.

In the time of the Internet, when more and more sensitive information is shared and exchanged via the web, this is of tremendous importance, he said.

But experts say an application like that may still be 10 years away.

Although the experiment was successful, the rate of sending and receiving entangled photons described in the paper was still quite low. Of nearly 6 million entangled photon pairs generated by Micius each second, only one pair was detected at stations here on Earth.

The communication rates here are not yet sufficient for a practical application, said Wenjamin Rosenfeld, a physicist at the Ludwig-Maximilians University in Munich.

However, he added that the mission represents a proof-of-principle demonstration of a quantum communication protocol that could be available in the near future.

Pan put it this way: This is the first baby step for quantum entanglement experiments going into space. It is really new!

Moving to Scuttle Obama Legacy, Donald Trump to Crack Down on Cuba - New York Times

Donald Trump doesn’t get the special counsel investigation. And he’s never going to. – CNN

Posted: at 9:43 pm

From his rise in Manhattan social circles to his career as a real estate developer to his time as a reality TV star, he's always employed these same basic tactics. If someone writes or says something Trump doesn't like, he either threatens to or actually sues while simultaneously pushing out a counter-narrative aimed at discrediting the initial report and turning the story toward more favorable ground for him.

Everything is to be treated as a tabloid story that can be shaped, changed, rebutted, knocked down and torn apart though force of will -- and words.

It's worked remarkably well for Trump. And so it shouldn't be all that surprising that he's brought that blueprint to Washington with him.

Except that the White House -- and the political and legal worlds it touches -- isn't the same thing that Trump is used to facing. Not at all. The rules governing this world aren't the rules of the tabloids of New York City media. Bob Mueller isn't some "Page Six" reporter.

Trump doesn't seem to have even the slightest understanding of that distinction. His twin tweets Thursday morning make that point better than I ever could.

This is standard-issue stuff in the Trump playbook. When attacked, attack back -- harder. Go after the story in big, broad ways -- "total hoax" is one way Trump has described the federal investigation -- and assume that the average person won't consume enough details or follow it closely enough to see whether you're right or wrong.

But this investigation isn't anything like what Trump has faced before. He can't simply say this is all a "witch hunt" or a "hoax" and have it disappear. Short of firing Mueller, which seems to me incredibly unlikely -- particularly after the leak of the obstruction investigation -- Trump can't stop it. The investigation will proceed no matter what Trump says about it or who involved in it he calls names. It will also, eventually, reach some conclusions about the nature of Russia's hacking of the election and whether or not there was any collusion in that effort by any member of the Trump campaign.

That train has already left the station. And Trump's ability to derail it is decidedly limited.

That doesn't mean Trump's use of his tried and true "attack, pivot, declare victory" strategy against Mueller and the special counsel investigation won't have any impact.

The more Trump casts the investigation as biased and unfairly targeted at him, the more his supporters will believe that it is. Which means that if Trump either fires Mueller -- again, that is so hard to imagine -- or works to discredit the final conclusions of the special counsel, there will be a ready bloc of his supporters eager to adopt and spread that message.

"I told you this whole special counsel was a witch hunt," you can imagine Trump saying to nods from his supporters. "Of course they concluded I was in the wrong. They had decided that before they even started investigating. We need to drain the swamp and make America great again."

That line will work with his supporters. But it won't change the underlying facts Mueller unearths -- and the reverberations they could cause among everyone outside of Trump's most loyal backers.

Trump is a blunt instrument. He knows one way of doing things. And that way has always worked for him. But this investigation is both more serious than anything Trump has faced before.

Almost everyone grasps that. Everyone except Donald John Trump, that is.

Australian leader is on the hot seat for making fun of Donald Trump – Washington Post

Posted: at 9:43 pm

Australian Prime Minister Malcolm Turnbull mimicked President Trump during a leaked speech at a ball in Australia hosted by the Federal Parliamentary Press Gallery on June 14. (AP)

You know what they say: In the age of smartphones, there's no such thing as off the record.

It's a lesson Australias prime minister just learned the hard way.

On Thursday, Malcolm Turnbull delivered a jovial speech at Parliament House's annual press ball, the equivalent of the White House Correspondents' Association dinner. In it, he made fun of the Australian government's dismal poll rankings. And he did so usinga verbal tick made popular by a certain world leader.

Donald and I, we are winning and winning in the polls, Turnbull said. We are winning so much. We are winning like we have never won before.To raucous laughter, he continued: We are winning in the polls. We are, we are not the fake polls, not the fake polls theyre the one were not winning in. Were winning in the real polls, you know, the online polls. They are so easy to win.

Though the speech was off the record, it was recorded on a phone and broadcast by the Nine Network.

Turnbullalso referenced Trump's Russia troubles. Referencing his supposed glowing polls, Turnbull asked: Did you know that? I know that, did you know that? I kind of know that. I know that. They are so easy to win. I have this Russian guy.

The prime minister later tried to walk back his remarks, telling Melbourne Radio 3AW that he was disappointed by the leak. Its a breach of protocol; its a breach of faith and all those things, he said. Though he also noted the obvious:He was only kidding. Its lighthearted, its affectionate, good-natured and the butt of my jokes was myself, the prime minister said.

The U.S. Embassyin Canberra released a statement saying it takes the impersonation with the good humor that was intended.

We understand that last nights event is equivalent to our own White House correspondents dinner, the embassy's statement reads.

Historically, Australia has been one of America's closest allies, though that relationship has been tested under Trump. Turnbull's first telephone call with Trump was, in the president's words, testy.Trump was surprised and angry to learn about a deal that required the United States to accept about 1,250 refugees who had made their way to Australia.

Since then, though, the pair has made an effort to appear close, at least in public. Turnbull is rarely critical of the U.S. president, and even shares some of his hard-line views about immigration.

The head of the Federal Parliamentary Press Gallery, which hosted the event, said he was disappointed that the non-publication agreement had been breached. But Laurie Oakes, who broke the story, said he had not attended the ball and did not think that journalists should be in the business of letting politicians go off the record at events they host.

The idea that there be no leak with hundreds of people in the room armed with mobile phones is just ridiculous, Oakes told the Associated Press.

Memo to Donald Trump: The election ended 219 days ago. You won. – CNN International

Posted: at 9:43 pm

That was 219 days ago.

And yet, on Thursday afternoon, Trump sent two tweets attacking his former opponent.

What these twin tweets suggest is something we already knew: Trump just can't quit the 2016 election, and Clinton.

He spent weeks reveling in his stunning win. He reminded anyone who asked -- and lots of people who didn't -- that he had won over 300 electoral votes, a feat people said was impossible for any Republicans. As his 100th day in office approached, Trump handed out electoral maps to reporters coming to talk to him about what he had done for those first 100 days.

Huge framed electoral maps were shown being brought into the White House.

The 2016 election represented Trump's greatest triumph, his life's work: Proving that all the elites who mocked him or said he couldn't do something were mistaken all along. They had to eat their words. He was right. Everyone else was wrong. The end.

Then there's the fact that Trump also works better when he has someone or something to run against. In Clinton, he found a perfect opponent -- someone as cautious as he was risky, someone as insider as he was outsider, someone as mannered as he was unruly.

The problem for Trump is that he won the election. It's over. Has been for a long time. (We are now closer to November 2017 than we are to November 2016.)

In winning, he became the president. And what the current president does or has done matters a whole lot more than what a losing candidate for president does, in the eyes of our criminal and legal systems.

(That's not unique to Trump. Many members of Congress -- of both parties -- have resigned in the face of legal problems, knowing that a former House member is a lot less juicy of a target than a sitting one.)

Then there are the specifics of the allegations Trump is making against Clinton in his tweets.

Here's the key paragraph:

"As the Russians gradually assumed control of Uranium One in three separate transactions from 2009 to 2013, Canadian records show, a flow of cash made its way to the Clinton Foundation. Uranium One's chairman used his family foundation to make four donations totaling $2.35 million. Those contributions were not publicly disclosed by the Clintons, despite an agreement Mrs. Clinton had struck with the Obama White House to publicly identify all donors. Other people with ties to the company made donations as well."

What Trump is arguing is, essentially, that the questions about the uranium mine sale and the plane visit should take precedence over the "hoax" that is the investigation into Russia's meddling in the 2016 election, potential collusion with his campaign and the possibility that he obstructed justice in the probe.

That is, of course, a matter of personal opinion -- and one Trump is very much entitled to. But remember that the special counsel was appointed by the deputy attorney general within the Trump administration. Bob Mueller was deputy AG Rod Rosenstein's pick, not Clinton's, or anyone else's. This was not a partisan action.

Trump is a victim of his own success here.

He won the election. He is the President -- and the most powerful person in the country. That means he gets a level of scrutiny no one else does. Particularly when there is so much smoke swirling regarding the ties between Russia and his campaign, and his decision to fire Comey in the midst of a federal investigation into those allegations.

Trump can try to distract. He can try to deflect. He can complain about Clinton's alleged transgressions. But what he can't change is the fact that he is President, and this investigation isn't going to disappear just because he sent two -- or two hundred -- tweets about Clinton.

Senate passes Russia sanctions bill, pushing back against Trump – CNN

Posted: at 9:43 pm

The Senate approved the bill 98-2, with Republican Rand Paul of Kentucky and Independent Bernie Sanders of Vermont voting against the measure. The bill, which includes both Russian and Iranian sanctions, now heads to the House, which still needs to pass it before it goes to President Donald Trump's desk.

The measure is widely seen as a rebuke to Trump, as it hits Russia with new sanctions to punish Moscow for its interference in US elections, as well as over Moscow's aggression in Ukraine and Syria.

The bill establishes a review process for Congress to have a say whether the White House eases Russia sanctions. It also establishes new sanctions against those conducting cyberattacks on behalf of the Russian government as well as supplying arms to Syrian President Bashar Assad, and it allows for sanctions to hit Russia's mining, metals, shipping and railways sectors.

"We moved to make the Congress, not the President, the final arbiter of sanctions relief when necessary," Senate Minority Leader Chuck Schumer said. "Any idea of the President that he can lift sanctions on his own for whatever reason are dashed by this legislation."

The Russia sanctions measure was added as an amendment to an Iranian sanctions bill, after a deal was struck between the heads of the Senate Foreign Relations and Banking Committees. The Russia amendment was added to the sanctions bill in a 97-2 vote on Wednesday.

Despite the overwhelming vote, the Russia sanctions package was no sure thing. Senate Foreign Relations Chairman Bob Corker of Tennessee had initially been hesitant to take it up, as the administration had expressed a hope it could improve relations with Moscow.

Secretary of State Rex Tillerson said this week that he was wary of Congress taking actions that could interfere with the administration's efforts to improve relations with Russia.

"What I wouldn't want to do is close the channels off," Tillerson told a Senate committee.

White House spokeswoman Sarah Huckabee Sanders said Thursday that the Trump administration is "committed to existing sanctions against Russia" but is "still reviewing the new Russia sanctions amendment."

"We will keep them in place until Moscow fully honors its commitment to resolve the crisis in Ukraine," Sanders said. "We believe the existing executive branch sanctions regime is the best tool for compelling Russia to fulfill its commitments."

Still, Corker and other Republicans said they expect Trump to sign the bill if it's passed by the House.

"I called over myself yesterday and just shared some thoughts with them. But look, this bill is going to become law," Corker told reporters on Wednesday. "I've had conversations with Tillerson more generally about our relationship with Russia, not about details (of the legislation)."

The Senate also passed two amendments before approving the bill. The first was a technical change that the sanctions would not apply to NASA and commercial space launches, as Russian rocket engines are used for the American Atlas V and Antares rockets.

The second reaffirmed "the strategic importance of Article 5" in NATO, the principle that an attack on one NATO member is an attack on all members of the alliance.

CNN's Dan Merica contributed to this report.

Donald Trump Blocked Me on Twitter for Telling Him He’s Not as Cool as Witches – Newsweek

Posted: at 9:43 pm

I reply to President Donald Trump'stweets sometimes.

I'm not proud of it. It's a compulsion, like biting fingernails or eating all the Doritos in the bag at once. When I wake up and see a blustery new message from our tweeter-in-chief, what am I supposed to do?Walk away? Perform yoga stretches? No. I carve out a snarkyretort. If I'm fast enough, I watch the likes and retweets roll in at lightning speed. (This is the 2017 equivalent of commenting "FIRST!" on an explosive message board thread.)

Sometimes, I try to debunk the misinformation Trump sharesthe false claimsabout an apologyletter from The New York Times, for instance, or the lies about his approval ratings. Other times, I just tweet Borat jokes.

Culture Emails and Alerts- Get the best of Newsweek Culture delivered to your inbox

Again: Not proud. The sight of some verified nobody pumping out atweetstorm in Trump's mentions has become such aclich that there are now numerous profiles of the people who do this every day. The genre is very ripe forparody:

I won't pretend this is some noble act of resistance (or, as they say, #resistance). It's just a quick shot ofdopamine when my tweet blows up. Plus, it'smomentarily satisfying to be able to talk back to Trump on the public medium he can'tstay away from. There isno historical precedent for Trump'sTwitter. The president of the United States communicates directly with us in unfiltered outbursts when he's at his angriest, and we get to respond. It's weird. Sometimes he even sees the responses. And then he gets madder.

On Thursday, Trump, or somebody with access to his account, must have seen my response to one of his tweets.I know this, because he blocked me.

The block came shortly after Trump tweeted about being caught in"the single greatest WITCH HUNT in American political history." (Presumably, he is referring to the Russia investigation.) The president's use of the phrase "witch hunt" is curious butahistorical. I sent a snarky reply telling Trump to stop comparing himself to witches, who've been persecuted far more than he is:

A few minutes later, I checked to see if Trump had done any more tweets. Instead, I found that he had blocked me. (If you're new to Twitter, this means I can't tweet at him or read his tweets anymore.)

Was I blocked due to a pattern of behavior or because that one joke hurt Trump's feelings? No idea.It would be flattering to think that the president has read the articles I've written about him, like the one in which I relayed the stories behind his terrible movie cameos or the one where I profiled his celebrity admirers. But that seems unlikely, since they don't get discussedonFox&Friends. Plus, Trump doesn't really seem to read,anyway.

Related: The ridiculous stories behind Donald Trump's movie and TV cameos

I'm not the first to be blocked. Trump has been making liberal use of the feature lately. He blocked the writer Bess Kalb, who frequently mocks his tweets. He evenblocked Stephen King the other day. Fellow author J.K. Rowling kindly offered to DM Trump's tweets to King:

In fact, Ashley Feinberg, over at Wired, has a running list of people Trump has blocked on Twitter. For a certain breed of journalist, being insulted by Trump is a badge of honor. CNN'sChris Cillizza, for instance, has had an unflattering quote from Trump in his Twitter bio for yearsproof that even a broken clock is right twice a day:

So I'm not alone. After I revealed I'd been blocked, I got some interesting replies. Random Trump-haters started tweeting at me with a strange mix of congratulations ("Welcome to the #BlockedByTrump club drinks are at 6," tweeted@BrandonTXNeely) and messages of condolence. "Wow, another one down," tweeted@MissNeverTrump, as though I'd been slain on the front lines of some war. One person shared a memethat says, "Live your life in such a way that Donald Trump blocks you on Twitter." (I assume this is an ancient Greek proverb.) Even the actress who voicedDil Pickles on Rugrats swung by to voice her support.

Meanwhile, I received a new wave ofvitriol from Trump supporters. One guy asked me if I support the recent shooting ofRepublicanRepresentative Steve Scalise. (I don't!) Another Twitter user called me a "dumb ass dork not worth anybody's time." (Tough, but fair.)

The weird thing about being blocked by Trump is that I can no longer look at his tweets, unless I open an incognito browser that was probably intended for porn, not statements from the president. This has worrisome constitutional implications. TheKnight First Amendment Institute has argued that Trump is violating people's right to free speech when he blocks them on Twitter.The Institute has threatened to file a lawsuit. "If theres any kind of forum the government is operating for expression, it may not discriminate on the basis of viewpoint," a senior fellow at the Institute told Wired.

Meanwhile, I now have no idea whether Trump has tweeted in the last hour. Is this whatfreedom feels like?

Actually, you know what? J. K. Rowling, if you're reading this, can you DM Trump's tweets to me, too?
