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…
The cost of universality: A comparative study of the overhead of state distillation and code switching with color codes
Michael E. Beverland, Aleksander Kubica, Krysta M. Svore
Estimating and reducing the overhead of fault tolerance (FT) schemes is a crucial step toward realizing scalable quantum computers. Of particular interest are schemes based on two-…
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…
Noncommuting conserved quantities in quantum many-body thermalization
Nicole Yunger Halpern, Michael E. Beverland, Amir Kalev
In statistical mechanics, a small system exchanges conserved quantities---heat, particles, electric charge, etc.---with a bath. The small system thermalizes to the canonical ensemb…
