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…
Union-Find Decoders For Homological Product Codes
Nicolas Delfosse, Matthew B. Hastings
Homological product codes are a class of codes that can have improved distance while retaining relatively low stabilizer weight. We show how to build union-find decoders for these…
Short Shor-style syndrome sequences
Nicolas Delfosse, Ben W. Reichardt
We optimize fault-tolerant quantum error correction to reduce the number of syndrome bit measurements. Speeding up error correction will also speed up an encoded quantum computatio…
Optimization of the surface code design for Majorana-based qubits
Rui Chao, Michael E. Beverland, Nicolas Delfosse +1
The surface code is a prominent topological error-correcting code exhibiting high fault-tolerance accuracy thresholds. Conventional schemes for error correction with the surface co…
