Kennedy, DeSalvo, Foss-Feig, Caroline, Borgna, Brad IssueVolume: 2026-06-17 Abstract: Quantum computers require both high-fidelity operations and large qubit numbers to surpass classical capabilities1. Trapped-ion platforms have demonstrated the highest gate fidelities of any modality2,该项研究成果发表在2026年6月17日出版的《自然》杂志上, J. P.,才能超越经典计算能力, 量子计算机需要同时具备高保真度操作和大量量子比特, Arkinstall, 本期文章:《自然》:Online/在线发表 近日, none of which are fundamentally limited and probably able to be improved. These component infidelities are predictive of system-level performance in both random Clifford circuits and random circuit sampling (RCS), Robert D., Drotar,为量子计算机的保真度和复杂度确立了新的前沿, Mayer, Evans。
