Tunable photon-assisted bleaching of three-level systems for noise filtration

Chun-Hsu Su, Andrew D. Greentree, Raymond G. Beausoleil +4

Electromagnetically-induced transparency (EIT) exploits quantum coherence to burn subnatural linewidth holes within a spectral line. We investigate the less explored properties of…

Anyonic Quantum Walks

Gavin K. Brennen, Demosthenes Ellinas, Viv Kendon +3

The one dimensional quantum walk of anyonic systems is presented. The anyonic walker performs braiding operations with stationary anyons of the same type ordered canonically on the…

Universal quantum computation using the discrete time quantum walk

Neil B. Lovett, Sally Cooper, Matthew Everitt +2

A proof that continuous time quantum walks are universal for quantum computation, using unweighted graphs of low degree, has recently been presented by Childs [PRL 102 180501 (2009…

Computation and Dynamics: Classical and Quantum

Vladimir V. Kisil

We discuss classical and quantum computations in terms of corresponding Hamiltonian dynamics. This allows us to introduce quantum computations which involve parallel processing of…

Engineering complex topological memories from simple Abelian models

James R. Wootton, Ville Lahtinen, Benoit Doucot +1

In three spatial dimensions, particles are limited to either bosonic or fermionic statistics. Two-dimensional systems, on the other hand, can support anyonic quasiparticles exhibit…

Measuring atomic NOON-states and using them to make precision measurements

David W. Hallwood, Adam Stokes, Jessica J. Cooper +1

A scheme for creating NOON-states of the quasi-momentum of ultra-cold atoms has recently been proposed [New J. Phys. 8, 180 (2006)]. This was achieved by trapping the atoms in an o…
