Chinese scientists achieve quantum computing advantage

A research team including renowned Chinese quantum physicist Pan Jienwei announced Friday a significant breakthrough in computing, achieving a quantum computing advantage. This was reported by Radio China.
The team created a prototype of a quantum computer called “Jiujan,” through which a maximum of 76 photons were detected. The study, which used a sample of gaus boson (GBS), a classic simulation algorithm, to provide a highly effective way to demonstrate quantum computing acceleration when solving some well-defined tasks, was published on the website of the journal Science (Science).

This achievement means that China has implemented the first major stage on the road to full-scale quantum computing — a quantum computing advantage, also known as “quantum supremacy.”

No traditional computer can perform the same task over a reasonable period of time, and acceleration is unlikely to be caught up by classic algorithmic or hardware improvements, according to the team.

Quantum computing is still at an initial level of research, but is considered key to radically improving the speed and processing power of computers, allowing them to simulate huge systems and process large-scale data, boosting achievements in physics, chemistry, biology and other areas. Chinese science teams are making serious efforts to break into this field, competing on internet giants such as Google, Microsoft and Amazon for a leading role in this technology.
