Abstract:

A method to simulate the dynamics of anyons through the Jaynes-Cummings model is presented. The simulation of anyons with m/2, m/3, m/4 statistics and transmution of statistics of the system from Fermi to Bose, through the anyonics statistics was also shown. The entanglement of the system eigenstates which provides a two-dimensional confinement in the effective evolution of the system plays an important role. It is also shown that it is possible to transmute the statistics of the system continuall7 from ferminons to bosons for particular parameters.

Abstract:

We present an idealized model involving interacting quantum dots that can support both the dynamical and geometrical forms of quantum computation. We show that by employing a structure similar to the one used in the Aharonov-Bohm effect we can construct a topological two-qubit phase-gate that is to a large degree independent of the exact values of the control parameters and therefore resilient to control errors. The main components of the set-up are realizable with present technology.
