DESCRIPTION:[b]Speaker: Ben Brown [/b](​IBM).\n\n[b]Abstract:[/b]\nIn semi
 nal work Alexei Kitaev proposed topological quantum computing\, whereby l
 ogic gates of a quantum computer are conducted by creating\, braiding and
  fusing anyonic particles on a two-dimensional plane. Furthermore\, he sh
 owed the proposal is inherently robust to local perturbations when anyons
  are created as quasiparticle excitations of a topologically ordered latt
 ice model prepared at zero temperature. Over the decades following this p
 roposal there have been considerable technological developments towards t
 he construction of a fault-tolerant quantum computer. Rather than maintai
 ning some target ground state at zero temperature\, a modern approach is 
 to actively correct the errors a target state experiences\, where we use 
 noisy quantum circuit elements to identify and subsequently correct for d
 eviations from the ideal state. We present an error-correction scheme tha
 t enables us to carry out robust universal quantum computation by braidin
 g anyons. We show that our scheme can be carried out on a suitably large 
 device with an arbitrarily small failure rate assuming circuit elements a
 re below some threshold level of local noise. The error-corrected scheme 
 we have developed therefore enables us to carry out fault-tolerant topolo
 gical quantum computation using modern quantum hardware that is now under
  development.
