Quantum computing with the fractional quantum Hall effect quasiparticles

Abstract: Topological quantum computation with anyons has been suggested as a way of implementing intrinsically fault-tolerant quantum computation. In the talk, I will discuss a proposal to implement the basic elements of the anyonic computation in systems of antidots in the two-dimensional electron liquid in the FQHE regime. The suggested scheme is based on the adiabatic transfer of FQHE quasiparticles in the antidot systems, and uses their fractional statistics to perform quantum logic. Also discussed will be the dephasing by the edge excitations and dc transport properties of the edge states.
