China’s Zuchongzhi 3.0 Quantum Processor ‘Outpaces’ Google Willow by Million Times

  • Chinese researchers from the University of Science and Technology of China (USTC) have unveiled the Zuchongzhi 3.0, a superconducting quantum processor with 105 qubits, surpassing Google Willow by a million times.
  • The Zuchongzhi 3.0 operates quadrillion times faster than the world's fastest supercomputer and achieves results that would take classical supercomputers over 6.4 billion years to replicate.
  • The processor showcases advancements in coherence time, gate fidelities, and readout accuracy, with a coherence time of 72 microseconds, single-qubit gate fidelity of 99.90%, two-qubit gate fidelity of 99.62%, and readout fidelity of 99.13%.
  • The research team plans to expand integration capabilities and has achieved previous successes with the Zuchongzhi-2 and Jiuzhang photonic systems.
