Error Mitigation Via Emulated Measurement of Stabilizers

ORAL

Abstract

While closed-loop control is the ideal for quantum error correction, open-loop techniques are more accessible given current technologies. Dynamical decoupling is the go-to error mitigation technique, but many of the noise mechanisms encountered in experimental implementations, such as microwave cross-talk or coherent gate errors, are not amenable to simple dynamical decoupling schemes. An alternative technique for these errors is to emulate measurement of stabilizer operators via the stochastic application of gates from the set of stabilizers. We demonstrate the error-mitigating effects of this emulated quantum measurement protocol on a small superconducting qubit processor.
