a, b Success decay curves from performing 5-qubit (blue), 10-qubit (orange), and 15-qubit (green) QIRB on ibmq_algiers. Experiments were performed with (a) and without (b) dynamical decoupling (DD) on idling qubits during MCMs. c Even with DD, the observed QIRB error rate (rΩ) and the MCM error rate (εMCM) are much larger than predicted by IBM's reported measurement error data, suggesting significant MCM-induced crosstalk errors that are not mitigated by DD. All error bars are 1σ bootstrapped error bars.
