Abstract
Scalable, parallelizable quantum error correction on surface codes can be performed using a decoder graph. Overlapping decoder graph windows can be generated using the decoder graph. First corrections can be independently determined for each of the overlapping decoder graph windows. First core corrections can be retained for core regions of each of the overlapping decoder graph windows. Non-overlapping decoder graph windows can be generated using the decoder graph. The temporal boundaries of the non-overlapping decoder graph windows can be the temporal boundaries of the corrected core regions of the overlapping decoder graph windows. Second corrections can be independently determined for each of the non-overlapping decoder graph windows based on the temporal boundaries of the corrected core regions. The first core corrections and the second corrections can be combined to form a complete set of corrections for the decoder graph.
