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