Abstract
Systems and methods for performing fault-tolerant post-selection (FTPS) on an encoded logical qubit. An FTPS controller receives syndrome graph data related to an encoded logical qubit. The encoded logical qubit includes a plurality of physical qubits encoded with a quantum error correcting code. The FTPS controller determines a respective magnitude for one or more logical gaps from the syndrome graph data, and determines an error metric based on the magnitudes of the logical gaps. The error metric is compared to a quality threshold, and depending on whether the quality threshold is met, the FTPS controller provides instructions to a quantum computing system to either keep or discard the logical qubit.
