Researchers at the University of Science and Technology of China (USTC), recently published a paper that outlined their efforts to execute a random circuit sampling (RCS) test on their 105 qubit Zuchongzhi 3.0 quantum processor unit (QPU). The paper, appearing in the APS Physical Review Letters, reported that the QPU achieved 106 samples in just a few hundred seconds, a task cited as infeasible on the most powerful classical supercomputers today and that USTC researchers claimed would require the US DOE’s Frontier HPC approximately 5.9×109 years to replicate. This follows a similar Google announcement made late last year that their 105 qubit Willow QPU performed a similar RCS test in under five minutes, which Google researchers said would have taken one of the fastest supercomputers 1025 years, a number that greatly exceeds the age of the universe.
