QUROPE Quantum Information Processing and Communication in Europe

In our new group at the University of Siegen (Germany) we are looking for a motivated PhD student in the field of quantum information theory. The research topics include:

• theory of multiparticle entanglement
• entanglement measures
• foundations of quantum mechanics, e.g. the Kochen-Specker theorem

Applicants are expected to have a master / diploma in physics, experience in theoretical physics and interest in foundational questions of quantum mechanics.

A PhD position is open in the atom optics group in Hamburg, Germany for studying the interaction of a Bose-Einstein condensate in an optical high finesse (> 500.000) cavity operating in the regime of resolved recoil sidebands.

We are investigating a range of systems in order to produce a robust quantum memory. For example, we recently showed how to store a quantum state in a nuclear spin for over three seconds [1], in a solid state system. We are now looking at ways of extending this coherence time, and at making the memory more versatile [2].

In this project, we aim to design improved quantum memories in both single spins and spin ensembles. There will be opportunities for collaboration with experimentalists both locally, and at the University of Oxford and Princeton.

This theoretical project is about the quantum properties of nanomaterials, which have atom-like discrete quantum energy levels. Examples of such systems include semiconductor quantum dots and molecular materials. We will be interested in how an optical driven field can create quantum coherence in these solid-state systems and how long this coherence can be maintained. We will go on to look at how energy can transfer between connected nano-materials and whether this influences the efficiency of the process.

One can regard quantum entanglement as the fundamental resource needed in order to execute quantum algorithms. Certain kinds of entangled states exist which are universal resources, in the sense that any quantum algorithm can be performed simply by performing a prescribed series of quantum measurements. Moreover, even the entangled state itself can by created by making measurements [1].

We have an opening for a PhD position in our High Finesse Cavity project, where we study the interaction of a BEC with a single mode of an optical resonator with half a million finesse and few kHz linewidth. We are looking for someone with a master or diploma degree in AMO-physics, interested in front line fundamental research.

The selected candidate shall benefit from international collaborations with theoretical and experimental groups.
Conditions: the candidates must have a Master or equivalent Diploma degree by the application deadline (15 Dec. 2010).
