A homological upper bound on critical probabilities for hyperbolic percolation
Nicolas Delfosse, Gilles Zémor
We study bond percolation for a family of infinite hyperbolic graphs. We relate percolation to the appearance of homology in finite versions of these graphs. As a consequence, we d…
Wigner function negativity and contextuality in quantum computation on rebits
Nicolas Delfosse, Philippe Allard Guerin, Jacob Bian +1
We describe a universal scheme of quantum computation by state injection on rebits (states with real density matrices). For this scheme, we establish contextuality and Wigner funct…
A note on the minimum distance of quantum LDPC codes
Nicolas Delfosse, Zhentao Li, Stéphan Thomassé
We provide a new lower bound on the minimum distance of a family of quantum LDPC codes based on Cayley graphs proposed by MacKay, Mitchison and Shokrollahi. Our bound is exponentia…
A decoding algorithm for CSS codes using the X/Z correlations
Nicolas Delfosse, Jean-Pierre Tillich
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 de…
