Magic state distillation (MSD) is the leading approach for producing the non-Clifford resources required for universal fault-tolerant quantum computation, but most analyses assume ideal projective stabilizer measurements. This assumption is questionable on near-term hardware, where measurement fidelity is limited and large quantum error-correcting codes are unavailable, and MSD exhibits a measurement-strength threshold distinct from the previously known threshold on input-state error.
