'''Magic state distillation''' is a protocol in quantum error correction that converts multiple noisy copies of a non-Clifford state into a smaller number of higher-fidelity copies, enabling fault-tolerant implementation of gates like the T gate. Because the Clifford group can be implemented transversally on many quantum codes, but the T gate cannot, magic state distillation bridges the gap between the operations that are easy to protect and the operations that are necessary for universal quantum computation. The protocol is the dominant source of overhead in most fault-tolerant quantum computing architectures, and the resource requirements of [[Quantum Gate Synthesis|quantum gate synthesis]] are often expressed entirely in terms of the number of ''magic states'' consumed.

The core idea, developed by Bravyi and Kitaev, uses a Clifford circuit to detect errors in encoded magic states by measuring stabilizers. A distillation circuit that takes n noisy states and outputs k cleaner states achieves a quadratic suppression of error per level, but the constant factors are severe: each level of distillation requires roughly 15 times as many input states as it produces. The resulting resource estimates mean that a single T gate in a high-precision quantum algorithm may require thousands of physical qubits dedicated to magic state production, making the protocol the binding constraint on scalable quantum computing.
