Bringing the Magic: Google Breaks Open a Bottleneck in Quantum Computing
Google, Thursday, October 15th, 2026
Google Quantum AI shows magic state cultivation working on its Willow processor, cutting errors about 40x.
Google Quantum AI reports that magic state cultivation works in practice on its Willow processor, reducing errors roughly 40x compared with running without it.
The result, published in Science, targets a long-recognized bottleneck: producing the high-quality, error-corrected magic states needed for universal quantum computing, which has been considered extremely resource-heavy.
Google calls the demonstration a crucial step toward scaling quantum computers to practical use.
