Quantum devices are often touted as performing better than classical ones, but the impact can seem far from our everyday lives. Researchers have now demonstrated a quantum optical microphone that listeners say produces a clearer sound than a classical counterpart [1]. The microphone was tested under specific conditions (low volume and high noise), outside of which the quantum advantage would not be noticeable. Despite this limitation, the new quantum techniques could prove useful elsewhere: they could eventually be used to improve imaging of biological samples.

Many high-precision measurements, such as gravitational-wave detection, rely on interferometers that measure interference effects, such as fringes, that arise when photons are sent through two possible paths. Using pairs of quantum-mechanically entangled photons reduces the random fluctuations (shot noise) in such measurements, which increases the measurements sensitivity. However, some common techniques involve measuring both photons in an entangled paira slow selection process that limits the measurement rate to 1 Hz. If you want to use entangled photons to follow fast action, like single molecules moving inside a biological cell, that rate is far too slow.

Florian Kaiser from the University of Stuttgart, Germany, and his colleagues have come up with a way to boost the measurement rate for such quantum-optics experiments by 10,000 times. In their setup, the input laser light first goes through a nonlinear crystal that creates a stream of pairs of entangled photons that are then fed into the two paths (or arms) of their interferometer.

To avoid having to measure both photons at the outputs of the interferometer, the team added an optical component called a wavelength-selective wave plate, which rotates the polarization of the light passing through one of the interferometers arms. It turns out that this simple manipulation encodes the two-photon information (the quantum phase of the pair) in just one of the photons.

Once the information is transferred to single photons, measuring the interference signal becomes easy: just take the difference of the light intensity at the two outputsthe same method as in classical interferometry. The team showed that they could obtain quantum-enhanced signal-to-noise measurements with sampling rates as high as 100 kHz. This frequency is high enough to generate high-quality audio, which allowed the researchers to demonstrate their technique in a sound recording experiment. We wanted to check if humans can actually hear the quantum improvement, Kaiser says.

The researchers transformed their interferometer into an optical microphone by attaching one of the mirrors to a membrane that vibrates in response to sound waves. As the mirror moves back and forth, it changes the length of one of the interferometer arms, producing an observable variation in the light reaching the detectors. The team used the microphone in a standardized hearing test. Selected words were recorded with the microphone and played back to a set of human listeners, who were asked to identify the words. A similar test was done with a classical optical microphone, in which the same interferometer was used but without any entanglement of photons. The subjects had slightly better success recognizing the quantum-recorded words.

Kaiser is quick to admit that the test was rigged. Our microphone has a quantum advantage in an artificial situation that we created here, he says. That situation involved turning down the volume during the recording sessions so that the measurement shot noise would be high relative to other noise contributions. Kaiser compares the noise level to the garbled transmissions between a race car driver and the pit crew, where only about half of the words are understood correctly.

But even if the new quantum technique wont revolutionize audio recording, it may benefit other types of measurements, such as biological imaging. Kaiser explains that most cells behave abnormally or can be damaged under intense illumination. A quantum microscope using the researchers entanglement scheme could improve high-resolution imaging techniques by allowing them to perform well using fewer photons.

Within the context of developing practical sensors, this new work stands as an elegant demonstration of the quantum advantage by using quantum states of light that exhibit entanglement, says quantum-optics expert Laurent Labont from the University of Nice Sophia Antipolis in France.

Its a very novel and ingenious synthesis of quantum metrology concepts, says Bill Plick from the University of Dayton, Ohio, who studies the foundations of quantum mechanics. Though I dont think this work could be called perception of something fundamentally quantum, it does kind of give people a way to get their hands around quantum effects and see that they can have a recognizable impactwhich is really cool.

Aqemia Announces an Extension of Its First Collaboration With Sanofi About AI and Quantum Physics-driven Drug Discovery in Oncology - Business Wire

The relationship between the mind and the brain is a mystery that is central to how we understand our very existence as sentient beings. Some say the mind is strictly a function of the brain consciousness is the product of firing neurons. But some strive to scientifically understand the existence of a mind independent of, or at least to some degree separate from, the brain.

The peer-reviewed scientific journal NeuroQuantology brings together neuroscience and quantum physics a crossroads that some scientists have used to explore this fundamental relationship between mind and brain.

An article published in NeuroQuantologys September 2017 edition reviews and expands on current theories of consciousness that arise from this meeting of neuro and quantum sciences.

Dr. Dirk K.F. Meijer, a professor at the University of Groningen in the Netherlands, hypothesizes that consciousness resides in a field surrounding the brain, a field which lies in another dimension. It shares information with the brain through a concept known as quantum entanglement, among other processes. This has certain similarities with a black hole.

This field may be able to pick up information from the Earths magnetic field, dark energy, and other sources. It then transmits wave information into the brain tissue, that is instrumental in high-speed conscious and subconscious information processing,wrote Dirk.

In other words, the mind is a field that exists around the brain; it picks up information from outside and communicates it into the brain at an extremely fast speed.

He described this field alternately as a holographic structured field, a receptive mental workspace, a meta-cognitive domain, and the global memory space of the individual.

Theres an unsolved mystery in neuroscience called the binding problem.Different parts of the brain handle different tasks: some work on processing color, some on processing sound, etc. But thisall somehow comes together as a unified perception, or consciousness.

Information merges and interacts in the brain more quickly than can be explained by current understandings of neural transmissions in the brain.It thus seems the mind is more than just neurons firing in the brain.

Neuroscientists are still searching for a mechanism behind this binding of disparate parts of the brains information processing. Meijerhas turned to quantum entanglement and tunneling for part of the answer.

Quantum entanglement is where particles appear to be connected despite vast distances between them. When actions are performed on one of the particles, corresponding changes are observed on the others simultaneously and instantaneously.

Quantum tunneling is a phenomenon where a particle tunnels through a barrier it shouldnt be able to according to classical physics.

These quantum phenomena allow for processes so rapid exceeding the speed of lightthey cant be explained with classical physics. So they could help explain ultra-fast subconscious mental processes.

If a mind or mental field could interact with the brain this way, that could be a step toward explaining the rapidity of mental processes.Meijer also used the wave-particle fluctuation of matter in quantum physics to explain the relationship between the mental field and brain. The idea is that particles, such as electrons and photons, exist as waves of probability, but also exist as particles in the event of those probabilities collapsing.

Similarly, Meijer said the mental field is both non-material and, simultaneously, part of the physical brain: The proposed mental workspace is regarded to be non-material, but in relation to the individual brain, entertains a non-dual wave/particle relation according to quantum physical principles: it is directly dependent on the brain physiology but not reducible to it.

The mind and the brain, said Meijer, are connected. They are unified, yet separate. Such an apparent paradox is a signature of quantum physics.

He hypothesizes that the mental field lies in another dimension: That we cannot directly perceive this information aspect is traditionally ascribed to a hidden fourth spatial dimension which cannot be observed in our 3-D world, but can be mathematically derived.

This fourth spatial dimension isnt time. Rather, it is a concept of space-time which includes four spatial dimensions, plus time a 4+1 space-time structure.

He cited studies that have suggested this concept of dimensions could reconcile the mismatches between traditional physics and quantum physics that plague scientists today.

Thus, the mind would exist in the fourth spatial dimension.

Meijer envisions a sort of screen or boundary between the outside world and the individual mental field. He likens this boundary to the event horizon of a black hole.

It is assumed that information entering a black hole from the outside is not lost, but rather is being projected on its outer screen, called the event horizon, Meijer wrote.

Consciousness is a boundary condition between a singularity (black hole) and space within the brain, he added, noting that the event horizon separates a mental model of reality for internal use in each individual from all that exists outside of it. Yet it is connected to a universal information matrix.

This dynamic holographic boundary collects information from inside the brain as well as from the information fields in which our brain is permanently embedded, he told The Epoch Times. In this manner, it is implicitly connected to a universal information matrix.

The geometrical shape known as a torus is well suited for the nature and functions Meijer attributes to this mental field.

A torus is described by the Merriam Webster dictionary as a doughnut-shaped surface generated by a circle rotated about an axis in its plane that does not intersect the circle.

Meijer presented various reasons related to physics theories for this shape. One is related to a theory of how electrical activity in the brain oscillates.

The torus structure is found in physics from the microscale, to the extreme macroscale of black holes, and the universe as a whole, Meijer explained. It could be instrumental in dynamically integrating information in the mind and brain.

Our paper, may directly contribute to an answer on the famous question of [cognitive scientists and philosopher David] Chalmers : how can something immaterial like subjective experience and self-consciousness arise from a material brain?Meijer wrote.

The ability of the mental field to pick up information from other fields, as conceived by Meijer, could also explain some anomalous phenomena, such as extrasensory perception, he noted.

In his view, consciousness can be regarded as the most basic building block of nature and consequently is present at all levels of the fabric of reality.

Since quantum physics emerged, scientists have been exploring its ability to explain consciousness, which Meijers work fits into.

Another theory called orchestrated objective reduction, or Orch-OR, was developed by physicist Sir Roger Penrose and anesthesiologist Dr. Stuart Hameroff, which on Hameroffswebsite hedescribesthusly: It suggests consciousness arises from quantum vibrations in protein polymers called microtubules inside the brains neurons.

Like Meijer, Penrose and Hameroff believethere is a connection between the brains biomolecular processes and the basic structure of the universe. They have also called for a major change in how scientists view consciousness.

Hameroff said in an interview with the blog Singularity: Most scientists cant explain consciousness in the brain, so they cant say that consciousness out of the brain is impossible.

Update:Dr. Dirk Meijer has provided The Epoch Times with an update on his paper, clarifying that quantum tunneling and entanglement are not the most likely methods of information transfer between the mental field and the brain. These two phenomena have been shown to provide only a correlation between two particles, not necessarily information transfer (although that may prove to be the case with further research).

Rather, quantum wave resonance is a more likely mechanism of extremely rapid information processing in the brain. This means, instead of signals being sent between neurons in the brain, a wave pattern that encompasses all neurons, as well as the mental field, transmits the information instantaneously.

Picture a vibration wave going up and down in a consistent pattern and running all through your brain and even outside of it. That pattern communicates information that can be understood by vibratory receptors in your brain. All of this is happening in a dimension and at a microscopic level not directly perceptible through conventional scientific instrumentation at our disposal today, yet can be inferred through physical and mathematical modeling.

Scientist Reveals 'Quantum Entanglement' May Explain the Mind Existing as a Field Separate From the Brain - The Epoch Times

Doctor Strange in the Multiverse of Madness, theatrically released in early May, develops the concept of the multiverse in the Marvel Cinematic Universe (MCU) by establishing how different universes interact with each other. As with most good science fiction, it represents a combination of both fiction and science in this case, quantum physics.

In quantum physics, multiverse hypotheses suggest that Earths universe may be one of many. Dr. Tony Crider, an astrophysics professor from Elon University, clarifies that theres no evidence of a multiverse yet, only untested models.

Multiple hypotheses about parallel universes exist, but Dr. Crider narrows it down to the three most prevalent, distinct and different models: Bubble Universes, Extra Dimensions and Many-Worlds models. The Many-Worlds model relates to the MCU most directly.

In classical physics, existing laws allow scientists to predict the outcome of certain situations. When a ball is thrown into the air with a certain amount of force, scientists can calculate how high it will go and when it will come back down.

However, this predictability does not work for the smaller scale of quantum physics. On a quantum level, each action can have many outcomes, and each potential outcome has a certain probability of happening.

Dr. Chris Richardson, another astrophysics professor at Elon University, explains that, in the Many-Worlds model, All of these different possible outcomes do occur, but only one of them occurs in our universe. All of the other possible outcomes occur in different universes.

In the Many-Worlds model, the universe diverges every time a decision is made, so that there are an infinite number of possible universes that can differ based on the smallest detail. For example, if a car has the option to turn left or right at an intersection, the Many Worlds model holds that the car turns in both directions a divergence into two different universes.

These universes can differ in the slightest way, such as the subtle difference in the direction that the car is turning, but eventually, over time, they can grow to become more distinct from one another.

In Doctor Strange in the Multiverse of Madness, theres a Doctor Strange in every universe, all variants of Stephen Strange played by Benedict Cumberbatch. The existence of the different versions of superhero Doctor Strange establishes that the car accident that caused Doctor Stranges injury and subsequent journey to study the mystic arts likely occurred in each universe.

Therefore, the divergence between those universes transpired after the accident at different points in time. Understanding the physics behind Doctor Strange in the Multiverse of Madness is not paramount, but establishing that concepts in science fiction, such as the multiverse in the MCU, are based on genuine science promotes an interest in science and makes the story more believable. By making the plot more credible, the film itself becomes more incredible.

The Martian, a film released in 2015 based on a book of the same name, follows the journey and trials of a human mission on Mars. Though the trip itself is aspirational and fictional, the film pulls from some scientific discoveries and hypotheses. Mark Watney can grow crops in the soil on Mars, which aligns with scientific evidence that the soil on Mars may even be more suitable for crops than Earths soil. Using human waste as fertilizer would make Watneys crops richer, which is also seen in the film.

Other science fiction evokes scientific discoveries as well. Prior to the Moon landing in 1969, multiple science fiction narratives and films from decades earlier imagined journeys to the Moon. The silent film Frau im Mond (Woman in the Moon) from 1929 presented whats considered the first relatively well-known science fiction narrative that introduced traveling to the Moon by rocket.

The film was predated by Le Voyage Dans la Lune (A Trip to the Moon) in 1902, which was seen by a smaller audience and was inspired by novels by both Jules Verne and H.G. Wells. Science fiction often creatively imagines what could be possible with some scientific evidence.

Frau im Mond and Le Voyage Dans la Lune prove that the fantasy of going to the Moon began decades before the space race. At the time, it seemed impossible to land humans on the Moon, but in 1961, President John F. Kennedy announced the United States ambition to send an American to Earths natural satellite.

With The Martian, the writers imagined a future with the resources for space travel to Mars that is safe for humans. The imagined future is growing closer, as some scientists believe humans may land on Mars as early as the 2030s. Earlier this year, Elon Musk had considered a mission to Mars in 2029.

Yet, while based on scientific theory, science fiction remains just that: fiction. Science fiction stories are often illogical and depart from science to enhance the plot. The ability to walk between parallel universes that America Chavez (Xochitl Gomez) shows off in Doctor Strange in the Multiverse of Madness is improbable, if not impossible.

Dr. Crider contradicts the logic behind the Sacred Timeline from Loki, by explaining that the Copernican Theory establishes that every time that you think that youre special, you should recognize that youre not. Despite the relations between the multiverse as seen in Doctor Strange in the Multiverse of Madness and the Many-Worlds theory, other MCU films and television shows appear less able to follow the model.

What If presents the closest resemblance to the Many-Worlds model, as one slight alteration in the timeline creates an entirely different world and story, but both Loki and Spider-Man: No Way Home have the same characters from different universes looking physically different.

How does Peter Parker exist in different universes with the same relatives but look completely different and age at a different rate? How does Lokis character have a crocodile variant?

Following the Many Worlds theory, all variants of Parker and all variants of Loki should appear in the same form, but the differences in appearance establish that science fiction is first and foremost fiction. Even with a scientific basis, the writers create a narrative that is marketable to an audience over one that follows scientific theories.

The multiverse that exists in Doctor Strange in the Multiverse of Madness and in the MCU relates to actual scientific models about parallel universes, but the films and television shows distance themselves from science by presenting narratives that align more with the writers visions and the audiences desires. The best science fiction is often linked to actual scientific theories because science provides ideas that writers can enhance to create stories that people want to read and see.

Where will the MCU go next? The MCUs next steps are anyones guess as audiences cannot predict the direction of the future of the MCU any more than scientists can predict the future of multiverse modeling. Fans can only be sure that the multiverse will continue to play a role in future MCU films.

The Multiverse in 'Doctor Strange' Has a Basis in Quantum Physics - Study Breaks

Sometimes the discovery of new physics demands insane levels of energy. Big machines. Fancy equipment. Countless hours of sifting through reams of data.

And then sometimes the right combination of materials can open a doorway to invisible realms in a space little bigger than a tabletop.

Take this new kind of relative to the Higgs boson, for example. It was found lurking in a room temperature chunk of layered tellurium crystals. Unlike its famous cousin, it didn't take years of smashing up particles to spot it, either. Just a clever use of some lasers and a trick for unweaving their photon's quantum properties.

"It's not every day you find a new particle sitting on your tabletop," saysKenneth Burch, a Boston College physicist and the lead co-author of the study announcing the discovery of the particle.

Burch and his colleagues caught sight of what's known as an axial Higgs mode, a quantum wiggle that technically qualifies as a new kind of particle.

Like so many discoveries in quantum physics, observing theoretical quantum behaviors in action get us closer to uncovering potential cracks in the Standard Model and even helps us hone in on solving some of the remaining big mysteries.

"The detection of the axial Higgs was predicted in high-energy particle physics to explain dark matter," says Burch.

"However, it has never been observed. Its appearance in a condensed matter system was completely surprising and heralds the discovery of a new broken symmetry state that had not been predicted."

It's been 10 years since the Higgs boson was formally identified amid the carnage of particle collisions by CERN researchers. This not only ended the hunt for the particle but loosely closed the final box in the Standard Model the zoo of fundamental particles making up nature's complement of bricks and mortar.

With the Higgs field's discovery, we could, at last, confirm our understanding of how components of the model gained mass while at rest. It was a huge win for physics, one we're still using to understand the inner mechanics of matter.

While any single Higgs particle exists for barely a fraction of a second, it's a particle in the truest sense of the word, blinking briefly into reality as a discrete excitation in a quantum field.

There are, however, other circumstances in which particles can bestow mass. A break in the collective behavior of a surge of electrons called a charge density wave, for example, would do the trick.

This 'Frankenstein's monster' version of Higgs, called a Higgs mode, can also appear with traits that aren't seen in its less patchwork cousin, such as a finite degree of angular momentum (or spin).

A spin-1 or axial Higgs mode not only does a similar job to the Higgs boson under very specific circumstances, it (and quasiparticles like it) could provide interesting grounds for studying the shadowy mass of dark matter.

As a quasiparticle, the axial Higgs mode can only be seen emerging from the collective behaviors of a crowd. Spotting it requires knowing its signature amid a wash of quantum waves and then having a way to sift it out of the chaos.

By sending perfectly coherent beams of light from two lasers through such material and then watching for telltale patterns in their alignment, Burch and his team uncovered the echo of an axial Higgs mode in layers of rare-earth tritelluride.

"Unlike the extreme conditions typically required to observe new particles, this was done at room temperature in a table top experiment where we achieve quantum control of the mode by just changing the polarization of light," says Burch.

It's possible there could be plenty of other such particles emerging from the tangle of body parts making up exotic quantum materials. Having a means of easily catching a glimpse of their shadow in the light of a laser could reveal a whole litany of new physics.

This research was published in Nature.

Researchers Discovered a New Kind of Higgs Relative in The Unlikeliest of Places - ScienceAlert

Global Mobility Call brought together more than 4,500 on-site attendees and 13,000 online attendees from 40 countries, with more than 1.3 million views of the live programme. In addition, 250 journalists have covered the more than 100 multi-sector dialogues, where over 300 panelists, representatives from public and private sectors, entrepreneurs, academics and experts have presented proposals, ideas, reports and reflections on the rapid processes of changes in mobility.

Among the main conclusions was the need to carry out national and international projects that promote digitalisation, decarbonisation, connectivity, intermodal and multimodal transport, industrial transformation, urban design, improvement of rural transport, funding and professional services.

The President of the Spanish Government, Pedro Snchez, closed the Global Mobility Call by stating that this forum "is the best example of the capacity for resilience, ambition to transform, the essential collaboration between the public and private sectors, the strength of companies and of Spanish society as a whole. Both private and public sectors share a special ability to face difficulties and adapt to new scenarios".

He has underlined that the uncertainties provoked by the war "should not delay" the sustainable mobility transformation.

In closing the event, the President of the Executive Committee of IFEMA MADRID, Jos Vicente de los Mozos, explained that these days at Global Mobility Call have shown "the inspiration and the keys to enter into business of enormous proportions, for which priority is to access recovery funds", while the event has generated "content and professional networking, which will translate into a real boost for sustainable mobility".

"We have to process the vast content and contacts of highest interest which have been produced during these days. It will be our job to organise and make this important legacy available to the different sectors and the thousands of professionals who have participated in Global Mobility Call", he said.

Global Mobility Call has responded to the need to bring together all mobility actors at a time of profound transformation. The need to act on both climate and energy crises, seizing the opportunity provided by the EUR 800 billion NextGenerationEU European recovery funds, has made Global Mobility Call an unprecedented opportunity to shape the future of a decarbonised, safe, digitised mobility, which respects the planet and the people's health, aligned with the Sustainable Development Goals, the Paris Agreement and the European Green Pact.

Among the panellists, Jeffrey Sachs, American economist and specialist in sustainable development, called for further digital development of mobility and insisted that this be approached as an integrated ecosystem of sectors, just as Global Mobility Call does.

Clotilde Delbos, CEO of Mobilize, stressed the need to work towards providing users with mobility services tailored to their needs.

Michio Kaku, physicist and futurist, predicted how the quantum physics of the future will generate computers that will connect to the brain and the robotisation of the automotive industry.

Adina Vlean, European Commissioner for Transport, highlighted the opportunity presented by the Next GenerationEU Funds to boost projects in many of Europe's mobility sectors. It was also stressed that it is important to make this coincide with the drive for energy transition, to make Europe less dependent on fossil fuels.

Monica Araya, Climate Mobility Advisor and member of the ClimateWorks & Partners' Steering Committee suggested incorporating into the sustainable mobility agenda the questions of generating employment, fostering talent and economic value, at a time when countries are trying to remain within supply chains, and society is very anxious about the climate crisis and the retraining of labour in many sectors.

Urban planner and MIT professor Carlo Ratti called for reflection on deep structural changes in the mobility of people, jobs and products, at a time of disruption accelerated by the Covid crisis and war.
