(FORTUNE) – 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.
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.
