1. A computer-implemented method for decoding syndromes of a quantum error correction code, the method comprising:
receiving syndrome data for a plurality of quantum error correction rounds performed on a plurality of qubits;
identifying a plurality of first windows each comprising a respective first subset of rounds of the syndrome data, wherein each first window has a respective first central block of rounds of the syndrome data surrounded by one or more respective first buffer blocks of rounds of the syndrome data;
decoding each first window to obtain a first committed correction for each respective first central block;
identifying a plurality of second windows each comprising a respective second subset of rounds of the syndrome data, wherein each second window comprises at least part of at least one first buffer block; and
decoding each second window to obtain a second committed correction for each second window.
