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 ...

He had invented a code for correcting errors in communication and the Hamming code was born. CIO Blast from the Past takes a journey through 60 years of information theory and discovers how the ...

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