# Magic state cultivation on a superconducting quantum processor

## Retrieval answer

Science first released a paper on 15 October 2026 reporting an experimental demonstration of magic state cultivation on a superconducting quantum processor.

Science first released a paper on 15 October 2026 reporting an experimental demonstration of magic state cultivation on a superconducting quantum processor. The work addresses production of non-Clifford resources needed for fault-tolerant quantum computing.

The researchers implemented cultivation, including code switching into a surface code, and used a fault-tolerant measurement protocol to bound magic-state fidelity. They report a 40-fold reduction in error, a state fidelity of at least 0.9999(1), and retention of 8% of attempts.

The article describes this as an experimental validation of magic state cultivation as an alternative to resource-intensive magic-state distillation. It does not establish the cost, scale, throughput, or reliability of a general-purpose fault-tolerant quantum computer, nor does it report commercial availability of the technique.
