The rapid development of noisy intermediate-scale quantum devices has made it an exciting time to study their resilience to gate errors and faulty measurement readouts. It is well known that certain quantum error correction codes can be used to ameliorate these undesirable effects. Some of these codes, such as topological codes in two dimensions, provide a robust way to store quantum information and perform computations fault-tolerantly up to a finite threshold in the error probability. Importantly, they are also robust to faulty measurements if the correction procedure is applied multiple times. Our proposal investigates the connection of adding this time variable to other quantum codes in one dimension higher, and vice-versa.
