TOPIC: Quantum information processing with cold Fermi gases in the fast pairing regime

Abstract
It is widely recognized that the main difficulty in designing devices which could process information using quantum states is related to the decoherence of local excitations about a ground state. A solution to this problem was proposed by Kitaev, relying on (non-local) topological excitations, carrying fractional electronic charge. However, a practical implementation of this proposal using specific Landau levels in fractional quantum Hall systems has proven elusive. We propose a different physical system (based on cold Fermi atoms) where non-abelian anyonic excitations can be realized and manipulated, and whose implementation might be achieved with the current technology.
