IBM has some new options for businesses wanting to experiment with quantum computing. <\/p>\n
Quantum computers, when they become commercially available, are expected to vastly outperform conventional computers in a number of domains, including machine learning, cryptography and the optimization of business problems in the fields of logistics and risk analysis. <\/p>\n
Where conventional computers deal in ones and zeros (bits) the processors in quantum computers use qubits, which can simultaneously hold the values one and zero. Thisto grossly oversimplifyallows a quantum computer with a 5-qubit processor to perform a calculation for 32 different input values at the same time. <\/p>\n
On Wednesday, IBM put a 16-qubit quantum computer online for IBM Cloud platform customers to experiment with, a big leap from the five-qubit machine it had previously made available. The company said that machine has already been used to conduct 300,000 quantum computing experiments by its cloud service users. <\/p>\n
But thats not all: IBM now has a prototype 17-qubit system working in the labs, which it says offers twice the performance of the 16-qubit machine. <\/p>\n
Quantum computing performance is hard to compare. Much depends on the quality of the qubits in the processor, which rely on shortlived atomic-level quantum phenomena and are thus somewhat unstable. <\/p>\n
IBM is proposing a new measure of quantum computing performance that it calls quantum volume, which takes into account the interconnections between the cubits and the reliability of the calculations they perform. <\/p>\n
The companys quantum computing division, IBM Q, has set its sights on producing a commercial 50-qubit quantum computer in the coming years. <\/p>\n
