DESCRIPTION:[b]Speaker: Ben Brown [/b](​IBM).\n\n[b]Abstract:[/b]\nIn semi

 rl=https://arxiv.org/abs/0707.1889]arXiv:0707.1889[/url])\, whereby logic
  gates of a quantum computer are conducted by creating\, braiding and fus
 ing anyonic particles on a two-dimensional plane. Furthermore\, he showed
  the proposal is inherently robust to local perturbations ([url=https://a
 rxiv.org/abs/cond-mat/0010440]arXiv:cond-mat/0010440[/url]\, [url=https:/
 /arxiv.org/abs/quant-ph/9707021]arXiv:quant-ph/9707021[/url]\, [url=https

 /abs/1001.4363]arXiv:1001.4363[/url]) when anyons are created as quasipar
 ticle excitations of a topologically ordered lattice model prepared at ze
 ro temperature. Over the decades following this proposal there have been 
 considerable technological developments towards the construction of a fau
 lt-tolerant quantum computer. Rather than maintaining 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 el
 ements to identify and subsequently correct for deviations from the ideal
  state. We present an error-correction scheme that enables us to carry ou
 t robust universal quantum computation by braiding anyons. We show that o
 ur scheme can be carried out on a suitably large device with an arbitrari
 ly small failure rate assuming circuit elements are below some threshold 
 level of local noise. The error-corrected scheme we have developed theref
 ore enables us to carry out fault-tolerant topological quantum computatio
 n using modern quantum hardware that is now under development.
