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.
