- westurner 2y agoScholarlyArticle: "Establishing a New Benchmark in Quantum Computational Advantage with 105-qubit Zuchongzhi 3.0 Processor" (2025) https://arxiv.org/abs/2412.11924 https://arxiv.org/abs/2412.11924 NewsArticle: "Superconducting quantum processor prototype operates 10^15 times faster than fastest supercomputer" https://phys.org/news/2025-03-superconducting-quantum-processor-prototype-faster.html https://phys.org/news/2025-03-superconducting-quantum-proces... : > The quantum processor achieves a coherence time of 72 μs, a parallel single-qubit gate fidelity of 99.90%, a parallel two-qubit gate fidelity of 99.62%, and a parallel readout fidelity of 99.13%. The extended coherence time provides the necessary duration for performing more complex operations and computations. [...] > To evaluate its capabilities, the team conducted an 83-qubit, 32-layer random circuit sampling task on the system. Compared to the current optimal classical algorithm, the computational speed surpasses that of the world's most powerful supercomputer by 15 orders of magnitude. Additionally, it outperforms the latest results published by Google in October of last year by 6 orders of magnitude, establishing the strongest quantum computational advantage in the superconducting system to date.
