Google 称在 Willow 芯片上把魔法态制备误差降低约 40 倍
Google Says It Just Cracked One of Quantum Computing's Biggest Bottlenecks
AI brief
In brief Google Quantum AI said Thursday that a technique called magic state cultivation cut errors about 40-fold on its Willow chip, producing magic states with 99.99% fidelity. Magic states are single-use resources needed to run useful quantum programs, and Google says some estimates put the cost of making them at up…
