Single-Shot Decoding and Fault-tolerant Gates with Trivariate Tricycle Codes
Abraham Jacob, Campbell McLauchlan, Dan E. Browne
While quantum low-density parity check (qLDPC) codes are a low-overhead means of quantum information storage, it is valuable for quantum codes to possess fault-tolerant features be…
Unlocking early fault-tolerant quantum computing with mitigated magic dilution
Surabhi Luthra, Alexandra E. Moylett, Dan E. Browne +1
As quantum computing progresses towards the early fault-tolerant regime, quantum error correction will play a crucial role in protecting qubits and enabling logical Clifford operat…
Online Gaussian elimination for quantum LDPC decoding
Sam J. Griffiths, Asmae Benhemou, Dan E. Browne
Decoders for quantum LDPC codes generally rely on solving a parity-check equation with Gaussian elimination, with the generalised union-find decoder performing this repeatedly on g…
Automorphism Ensemble Decoding of Quantum LDPC Codes
Stergios Koutsioumpas, Hasan Sayginel, Mark Webster +1
We introduce AutDEC, a fast and accurate decoder for quantum error-correcting codes with large automorphism groups. Our decoder employs a set of automorphisms of the quantum code a…
Engineering Quantum Error Correction Codes Using Evolutionary Algorithms
Mark Webster, Dan Browne
Quantum error correction and the use of quantum error correction codes is likely to be essential for the realisation of practical quantum computing. Because the error models of qua…
