Decoding non-Abelian topological quantum memories
James R. Wootton, Jan Burri, Sofyan Iblisdir +1
The possibility of quantum computation using non-Abelian anyons has been considered for over a decade. However the question of how to obtain and process information about what erro…
A simple decoder for topological codes
James R. Wootton
Here we study an efficient algorithm for decoding the topological codes. It is based on a simple principle, which should allow straightforward generalization to complex decoding pr…
Enhanced thermal stability of the toric code through coupling to a bosonic bath
Fabio L. Pedrocchi, Adrian Hutter, James R. Wootton +1
We propose and study a model of a quantum memory that features self-correcting properties and a lifetime growing arbitrarily with system size at non-zero temperature. This is achie…
Novel Topological Phases and Self-Correcting Memories in Interacting Anyon Systems
James R. Wootton
Recent studies have shown that topological models with interacting anyonic quasiparticles can be used as self-correcting quantum memories. Here we study the behaviour of these mode…
An efficient Markov chain Monte Carlo algorithm for the surface code
Adrian Hutter, James R. Wootton, Daniel Loss
Minimum-weight perfect matching (MWPM) has been been the primary classical algorithm for error correction in the surface code, since it is of low runtime complexity and achieves re…
