High-threshold magic state distillation with quantum quadratic residue codes

Quantum Physics 2026-03-20 v1

Abstract

We present applications of quantum quadratic residue codes in magic state distillation. This includes showing that existing codes which are known to distill magic states, like the 55-qubit perfect code, the 77-qubit Steane code, and the 1111-qutrit and 2323-qubit Golay codes, are equivalent to certain quantum quadratic residue codes. We also present new examples of quantum quadratic residue codes that distill qubit TT states and qutrit Strange states with high thresholds, and we show that there are infinitely many quantum quadratic residue codes that distill TT states with a non-trivial threshold. All of these codes, including the codes with the highest currently known thresholds for TT state and Strange state distillation, are unified under the umbrella of quantum quadratic residue codes.
