Chinese quantum computer ‘sets record’ in processing test

Developers say the Zuchongzhi device can do in just over an hour a task that supercomputers would take years to achieve. Results surpass those produced by Google’s Sycamore processor in an experiment two years ago, they say. — SCMP

Scientists in China have claimed another benchmark in computing, saying their quantum device takes just 72 minutes to do a task that would take the most powerful supercomputer at least eight years.

In a non-peer-reviewed paper released late last month, the team led by Pan Jianwei, a physicist from the University of Science and Technology of China in Hefei, said the Zuchongzhi quantum processor set a record to challenge “classical computing”.
