Magic State Cultivation
A technique that uses properties of quantum error-correcting codes to prepare high-quality magic states directly on physical hardware. Compared with conventional magic state distillation methods, it is more efficient and can reduce resource overhead and improve logical fidelity.
Timeline (last 90 days)
Google Quantum AI achieved magic state cultivation on physical hardware for the first time on the Willow processor, reducing the error rate by a factor of 40 and reaching a logical fidelity of 99.99%.
Google's magic state cultivation technique exploits the properties of quantum error-correcting codes to directly cultivate high-quality magic states on physical hardware, rather than purifying them through multiple rounds of distillation.
There is still a gap between laboratory demonstrations and truly solving real problems; magic state cultivation needs to be verified on more qubits and in more complex algorithms, and the overall resource overhead still needs further optimization.
