Benchmarking mid-circuit measurement and reset

ORAL

Abstract

Mid-circuit measurement and reset is a crucial primitive in quantum error correction but so far there have been few demonstrations and even fewer methods proposed to benchmark performance. We present a new method, based on randomized benchmarking, to estimate performance of mid-circuit measurement and reset that quantifies the effects on the target qubit as well as any crosstalk errors on nearby qubits. We use the method to benchmark mid-circuit measurement and reset on Honeywell System Model H0 and find measurement and reset on the target qubit have high fidelity with low crosstalk errors on nearby qubits thanks to a new micromotion hiding technique, which is presented independently.
