Description
Topologically ordered phases of matter have recently
become a focus of much attention, both theoretical and
experimental. In two spatial dimensions such phases may
support anyons – quasiparticles that are neither bosons nor
fermions. Moreover, anyons with non-Abelian statistics can
occur, particularly in the fractional quantum Hall regime.
In this talk, I will focus on solid state interferometers
designed to detect such exotic statistics. I will discuss recent
experiments in the the quantum Hall regime at 5/2 filling
where the evidence for the existence of non-Abelian anyons
may have in fact been observed for the first time. I will also
mention potential applications of such interferometeric
schemes for topological quantum computation.
