- Race toward radical leaps in computing power heating up
- Another front in the wide-ranging U.S.-China tech contest
Chinese scientists claim to have built a quantum computer that is able to perform certain computations nearly 100 trillion times faster than the world’s most advanced supercomputer, representing the first milestone in the country’s efforts to develop the technology.
The researchers have built a quantum computer prototype that is able to detect up to 76 photons through Gaussian boson sampling, a standard simulation algorithm, the state-run Xinhua news agency said, citing research published in Science magazine. That’s exponentially faster than existing supercomputers.
While still in its infancy, quantum computing is seen as the key to radically improving the processing speed and power of computers, enabling them to simulate large systems and drive advances in physics, chemistry and other fields. Chinese researchers are competing against major U.S. corporations from Alphabet Inc.’s Google to Amazon.com Inc. and Microsoft Corp. for a lead in the technology, which has become yet another front in the U.S.-China tech race.
