Efficient Decoders for Qudit Topological Codes
Hussain Anwar, Benjamin J. Brown, Earl T. Campbell +1
Qudit toric codes are a natural higher-dimensional generalization of the well-studied qubit toric code. However standard methods for error correction of the qubit toric code are no…
Entropic Barriers for Two-Dimensional Quantum Memories
Benjamin J. Brown, Abbas Al-Shimary, Jiannis K. Pachos
Comprehensive no-go theorems show that information encoded over local two-dimensional topologically ordered systems cannot support macroscopic energy barriers, and hence will not m…
Topological Entanglement Entropy with a Twist
Benjamin J. Brown, Stephen D. Bartlett, Andrew C. Doherty +1
Defects in topologically ordered models have interesting properties that are reminiscent of the anyonic excitations of the models themselves. For example, dislocations in the toric…
