Abstract
A computing system including one or more processing devices configured to identify one or more severe hook faults in a stabilizer channel. Identifying the severe hook faults includes receiving a circuit channel check matrix, the columns of which indicate values of checks associated with elementary faults of the stabilizer channel. Identifying the severe hook faults further includes receiving a phenomenological channel check matrix as a sub-matrix of the circuit channel check matrix, receiving a logical effect matrix, and receiving a weight vector that indicates probability weights of the elementary faults. Based at least in part on the circuit channel check matrix, the logical effect matrix, the phenomenological channel check matrix, and the weight vector, identifying the severe hook faults further includes computing column indices of columns of the circuit channel check matrix that correspond to the severe hook faults. The processing devices output an indication of the severe hook faults.
