Topological quantum computation

The aim of the seminar is to give an introduction to topological quantum computation. We start by explaining how two logical qubits can be encoded in a torus due to degenerate physical qubits configurations. The physical stability of such systems are the main motivation for its use in quantum computation, this issue is related to error detection and correction at physical level. Possible gates and state measurement can be implemented trough the use of anyons and vortexes and the respective braiding. We also give a brief overview of topological and conformal field theories and discuss the possibility of its use for quantum computation.
