The Pfaffian state is an attractive candidate for the observed quantized Hall plateau at a Landau-level filling fraction nu=5/2. This is particularly intriguing because this state has unusual topological properties, including quasiparticle excitations with non-Abelian braiding statistics. In order to determine the nature of the nu=5/2 state, one must measure the quasiparticle braiding statistics. Here, we propose an experiment which can simultaneously determine the braiding statistics of… Expand

Anyonic braiding in optical lattices
This work explicitly work out a realistic experimental scheme to create and braid the Abelian topological excitations in the Kitaev model built on a tunable robust system, a cold atom optical lattice, and demonstrates how to detect the key feature of these excitations: their braiding statistics.

Demonstrating anyonic fractional statistics with a six-qubit quantum simulator.
An experimental demonstration of the fractional statistics of anyons in the Kitaev spin lattice model using a photonic quantum simulator and a phase shift of pi related to the anyon braiding is observed, confirming the prediction of the denominator statistics of Abelian 1/2 anyons. Expand
Detecting non-Abelian statistics in the nu = 5/2 fractional quantum hall state.
An interferometric experiment to detect non-Abelian quasiparticle statistics--one of the hallmark characteristics of the Moore-Read state expected to describe the observed fractional quantum Hall effect plateau at nu = 5/2 is proposed. Expand

Competing ν = 5/2 fractional quantum Hall states in confined geometry
Using measurements of tunneling between edge states, it is suggested that both the Abelian and non-Abelian states can be stable in the same device but under different conditions, and suggests that there is an intrinsic non- Abelian 5/2 ground state but that the appropriate confinement is necessary to maintain it.
