A decoding algorithm for CSS codes using the X/Z correlations

arXiv:1401.6975 · doi:10.1109/ISIT.2014.6874997

Abstract

We propose a simple decoding algorithm for CSS codes taking into account the correlations between the X part and the Z part of the error. Applying this idea to surface codes, we derive an improved version of the perfect matching decoding algorithm which uses these X/Z correlations.
