Abstract
A computing system comprises a quantum computing device including a plurality of logical qubits that each include a respective plurality of physical qubits; and a controller. The controller is configured to determine an error metric value of a qubit error metric for a logical qubit of the plurality of logical qubits at least in part by: at the logical qubit, performing a Pauli measurement sequence including a plurality of Pauli measurements; and computing the error metric value based at least in part on respective results of the plurality of Pauli measurements. Computing the error metric value includes computing respective assignment error probabilities of the Pauli measurements; and/or computing respective mutual unbiasedness values of pairs of non-commuting Pauli measurements that are adjacent in the Pauli measurement sequence. The controller is further configured to output the error metric value.
