Fault-Tolerant Quantum Gates with Defects in Topological Stabiliser Codes
Paul Webster, Stephen D. Bartlett
Braiding defects in topological stabiliser codes has been widely studied as a promising approach to fault-tolerant quantum computing. Here, we explore the potential and limitations…

Braiding defects in topological stabiliser codes of any dimension cannot be universal
Paul Webster, Stephen D. Bartlett
Braiding defects in topological stabiliser codes has been widely studied as a promising approach to fault-tolerant quantum computing. We present a no-go theorem that places very st…

Locality-Preserving Logical Operators in Topological Stabiliser Codes
Paul Webster, Stephen D. Bartlett
Locality-preserving logical operators in topological codes are naturally fault-tolerant, since they preserve the correctability of local errors. Using a correspondence between such…
