Error Mitigation Via Emulated Measurement of Stabilizers

Error mitigation techniques are critical for quantum information processing in the era of Noisy Intermediate-Scale Quantum technology. Strategies for mitigating coherent errors are of particular interest, since infidelity grows linearly with incoherent errors but can grow quadratically with coherent errors. Randomized compiling has been gaining traction as a technique that mitigates coherent errors by rendering them incoherent. In this work, we discuss an alternative error mitigation technique called Quantum Measurement Emulation (QME) which addresses coherent errors in logical qubits by emulating the measurement of stabilizer operators via stochastic gate application. We show how QME leads to a first-order insensitivity to coherent errors and describe how it compares to randomized compiling.
