Abstract
A computer-implemented method for use in decoding syndromes of a quantum error correction code, the syndromes comprising measurement data from a quantum computer comprising a plurality of syndrome qubits and a plurality of data qubits. The method comprises: processing the syndromes to identify defects; recording, in a data structure, respective locations for each defect; and determining a respective radius, for each respective defect, of a ball surrounding the respective location of the respective defect, and recording each respective radius with its respective location in the data structure, wherein each respective radius is determined by iteratively increasing a length of the respective radius until each respective radius defines a ball touching or overlapping at least one other ball surrounding another of the respective locations, such that each respective location belongs to a cluster consisting of an even number of the locations of the defects; wherein the data structure thereby enables decoding of the quantum error correction code.
