China develops quantum computer amid tech race with US
Chinese scientists say they have developed the world's fastest quantum computer, capable of performing calculations that a regular computer would take billions of years to solve.
The leading quantum research group published its findings about the quantum computer in the journal Science on Thursday.
Chief professor behind the study, Lu Chaoyang, said the team achieved the breakthrough by manipulating photons, particles of light.
The breakthrough represents a quantum computational advantage, also known as quantum supremacy, in which no traditional computer can perform the same task in a reasonable amount of time and is unlikely to be overturned by algorithmic or hardware improvements, according to the research.
It also said the prototype was 100 trillion times faster than Japan’s Fukagu supercomputer, launched in June.
Last year, Google announced that it had built a computer capable of performing a computation in 200 seconds that would take the fastest supercomputers 10,000 years.
Chinese scientist said that their computer is 10 billion times faster than Google’s Sycamore machine.
No quantum computer is yet ready to do useful work in the world.
The Asian power, which is in a technological race with the US to achieve quantum supremacy, is building a $10 billion National Laboratory for Quantum Information Sciences.
