Classification: CPC H  G | IPC G  H

Claim 0:
1. A computer-implemented method for decoding syndromes of a quantum error correction code, the syndromes comprising measurement data from a quantum computer, the method comprising:
receiving syndrome measurement data comprising a plurality of quantum error correction rounds performed on a plurality of qubits;
identifying a plurality of non-overlapping first blocks within the syndrome measurement data, wherein:
each first block has:
a first central block of quantum error corrections rounds; and
a first buffer block of quantum error correction rounds, wherein the first buffer block surrounds the first central block, and

each first block is surrounded by an interstitial region of quantum error correction rounds;

identifying the location of a first set of errors in the plurality of qubits by decoding each first block to provide respective decoded first central blocks and respective decoded first buffer blocks;
outputting the location of the first set of errors contained within each decoded first central block.
