Magic state cultivation is a quantum error correction technique that Google Quantum AI has demonstrated on its Willow superconducting processor. Magic states are the resource needed to implement non-Clifford gates for fault-tolerant quantum computing, and producing them with low error has traditionally been costly in qubits and operations. Cultivation aims to prepare them at lower overhead.
According to a creator summary of the announcement, the demonstration cut errors roughly 40x and reached about 99.99% fidelity. These figures come from secondary coverage and were not confirmed on the fetched official page, which lists the work only as a recent post titled "Magic State Cultivation on our Willow processor". The approach could reduce the hardware needed for large-scale quantum computers, though larger-scale demonstrations are still required.
This is a research result, not a product. It is not an API, model or downloadable tool. Access to Willow hardware is offered only through programs such as Google's Willow Early Access Program, which is a call for proposals.
