Google Quantum AI 于 2026 年 10 月 15 日在《科学》杂志上宣布，其在 Willow 量子处理器上成功演示了魔术态培养技术。
Google Demonstrates Magic State Cultivation on Willow Processor to Cut Quantum Error Rates Google Quantum AI announced in the journal Science on October 15, 2026, that it successfully demonstrated magic state cultivation on its Willow quantum processor.
此前，制造纠错魔术态曾占用量子计算机高达 95% 的容量，成为一项重大工程瓶颈。
The breakthrough addresses a major engineering bottleneck where creating error-corrected magic states previously required up to 95 percent of a quantum computer's capacity.
研究人员通过过滤协议并在颜色码和表面码之间嫁接态，实现了错误率降低 40 倍，并产生了逻辑保真度达 99.99% 的 T 态。
Using a filtering protocol and grafting states between color codes and surface codes, researchers achieved a 40-fold reduction in errors and produced T-states with 99.99 percent logical fidelity.
谷歌指出，尽管在实现实际容错量子计算之前仍需进一步扩展，但该实验在物理硬件上验证了一种关键的理论方法。
Google noted that while further scaling is required before achieving practical fault-tolerant quantum computing, the experiment validates a key theoretical method on physical hardware.
