Constant-overhead quantum error correction with thin planar connectivity
Maxime A. Tremblay, Nicolas Delfosse, Michael E. Beverland
Quantum LDPC codes may provide a path to build low-overhead fault-tolerant quantum computers. However, as general LDPC codes lack geometric constraints, naïve layouts couple many d…
Bounds on stabilizer measurement circuits and obstructions to local implementations of quantum LDPC codes
Nicolas Delfosse, Michael E. Beverland, Maxime A. Tremblay
In this work we establish lower bounds on the size of Clifford circuits that measure a family of commuting Pauli operators. Our bounds depend on the interplay between a pair of gra…
Improved quantum error correction using soft information
Christopher A. Pattison, Michael E. Beverland, Marcus P. da Silva +1
The typical model for measurement noise in quantum error correction is to randomly flip the binary measurement outcome. In experiments, measurements yield much richer information -…
Toward a Union-Find decoder for quantum LDPC codes
Nicolas Delfosse, Vivien Londe, Michael Beverland
Quantum LDPC codes are a promising direction for low overhead quantum computing. In this paper, we propose a generalization of the Union-Find decoder as adecoder for quantum LDPC c…
