Google says the Willow chip reduced the preparation error rate of Magic States by approximately 40 times through the Cultivation method; the related research was published in Science. The research has not yet met the practical engineering conditions required to crack Bitcoin wallets.
BlockBeats reported that Google Quantum AI released research related to the Willow chip, stating that the new technique reduces errors by approximately 40 times and achieves an accuracy of 99.99%, though its effectiveness at scale remains to be verified.
VeloNews, citing “Coin Blogs,” reported that Google verified in quantum computing that “magic state cultivation” can reduce the error rate by 40 times. This claim has no corroborating original announcement or independent source.
