Improved Methods for Determining Quantum Error Correcting Code Performance and Fault Tolerance
Michael Mullan, Matthew Weippert, Winton Brown
One of the central challenges in quantum error correction is determining the performance of a code in the low-error regimes needed to implement utility-scale computations. While pe…
Randomized Benchmarking with Restricted Gate Sets
Winton G. Brown, Bryan Eastin
Standard randomized benchmarking protocols entail sampling from a unitary 2 design, which is not always practical. In this article we examine randomized benchmarking protocols base…
Experimentally accessible witnesses of many-body localisation
M. Goihl, M. Friesdorf, A. H. Werner +2
The phenomenon of many-body localised (MBL) systems has attracted significant interest in recent years, for its intriguing implications from a perspective of both condensed-matter…
Short random circuits define good quantum error correcting codes
Winton Brown, Omar Fawzi
We study the encoding complexity for quantum error correcting codes with large rate and distance. We prove that random Clifford circuits with gates can be used to e…
Decoupling with random quantum circuits
Winton Brown, Omar Fawzi
Decoupling has become a central concept in quantum information theory with applications including proving coding theorems, randomness extraction and the study of conditions for rea…
Scrambling speed of random quantum circuits
Winton Brown, Omar Fawzi
Random transformations are typically good at "scrambling" information. Specifically, in the quantum setting, scrambling usually refers to the process of mapping most initial pure p…
