Google Quantum AI 首次在 Willow 处理器上演示 magic state cultivation，逻辑保真度达 99.99%
Google Quantum AI 团队首次在物理硬件上演示 magic state cultivation，在 Willow 处理器上相比此前方法实现 40x 错误率降低，达到 99.99% 的 SOTA 逻辑保真度。该成果今日发表于 Science，是迈向实用化纠错量子计算机的一步。
Some magical progress towards "magic state" in quantum!
Our @GoogleQuantumAI team has demonstrated "magic state cultivation" on physical hardware for the first time. The result is a 40x error reduction on our Willow processor vs. previous methods, achieving a state-of-the-art 99.99% logical fidelity.
It's another step towards useful, error-corrected quantum computers to help solve the hardest problems. The result is published in Science today, watch the video below to see how it works
