Why repetition codes matter The focus on repetition codes isn't arbitrary. While other quantum error-correcting codes, like surface codes, have only achieved small distances and relatively high ...

Minimum-weight perfect matching (MWPM) algorithms are commonly used to tackle the decoding problem in quantum error correction.

Technical Terms Error-Correcting Output Codes (ECOC): A framework used to decompose multi-class classification problems into multiple binary classification tasks through a coding matrix.
