Physical Review Journal Club: Superconducting Quantum Computing Beyond 100 Qubits

In the relentless pursuit of quantum computational advantage, a significant advancement is the development of Zuchongzhi 3.0. This superconducting quantum computer prototype, comprising 105 physical qubits, achieves high operational fidelities, with single-qubit gates, two-qubit gates, and readout fidelity at 99.90%, 99.62%, and 99.13%, respectively. Experiments with an 83-qubit, 32-cycle random circuit sampling on the Zuchongzhi 3.0 highlight its superior performance on tasks estimated to be infeasible on the most powerful classical supercomputers.

This leap in processing power places the classical simulation cost 6 orders of magnitude beyond Google’s SYC-67 and SYC-70 experiments, firmly establishing a new benchmark in quantum computational advantage.
