Entanglement with experimentalists and theorists
25th May Dr. Erika Andersson Heriot Watt University

With the exception of quantum key distribution, experiments in quantum information science are far behind theoretical work. It is important to try to bridge this gap. I will start by briefly describing two fruitful collaborations between theorists and experimentalists. First, together with the Optics group at Glasgow University, we have recently been able to obtain violations of Bell inequalities in 11 x 11 dimensions using the orbital angular momentum of light. This demonstrates that light with orbital angular momentum can provide high-dimensional entangled states for quantum information. Using high-dimensional entanglement, it may also be feasible to close the detection loophole. The second topic is a realisation of a quantum walk using a compact and scalable fibre loop setup, in collaboration with the University of Erlangen. Quantum walks have been shown to speed up search problems and to play a role as a computational primitive. The fibre loop setup, due to its flexibility, provides a rich playground for investigations of the physics of quantum walks. A theoretical proposal which we hope would be feasible to implement is a scheme to entangle nanocantilevers using interaction mediated by a Bose-Einstein condensate. If the main decay channel is through the condensate, then an initially separable state of the combined system would relax towards a state where the two nanocantilevers are entangled.

First year seminar
6th June (10am group meeting time) Christoph Vaillant Durham University AtMol

Calculations of exited state lifetimes in atoms provide a rich testing ground for our understanding of multielectron effects. We specifically examine the calculations of natural lifetimes along the perturbed singlet 5snd series of strontium, and the calculations of widths in high angular momentum autoionising states

Rydberg Lithium interacting with weak electric fields
8th June Dr. Derek Richards The Open University

Resheduled next term
15th June Prof. Stefan Maier Imperial College London

Topological defects in multi-component Bose-Einstein condensates
23rd June Dr. Peter Mason Université Pierre et Marie Curie

I will look at the ground state and topological defects of two coupled nonlinear Schrodinger equations modelling rotating two component condensates in terms of the different physical parameters. We  I will introduce a nonlinear sigma model which allows for a description of the system in terms of a single equation with a 'pseudospin'.'
