The Cryptography group at the University of Tartu, Estonia, is looking
for a researcher (postdoc) in cryptography, preferably with strengths
on one of the following topics:

Postdoctoral Fellowships at the Institute for Quantum Computing

The Institute for Quantum Computing is inviting applications for postdoctoral positions in all aspects of quantum information processing, bridging areas from fundamental theory to physical implementations.

Research Associate in Quantum Coherence in Non-equilibrium Light Matter Systems

UCL, Physics and Astronomy

Salary (inclusive of London allowance) £32,375 - £39,132 per annum

Start: as soon as possible

Duties and Responsibilities:

The main aim of this project is to explore novel emergent phenomena in far from equilibrium quantum systems with a particular focus on light-matter systems such as microcavity polaritons, quantum spins, circuit and cavity QED systems. There are two Research Associates positions available on this project.

Applications are invited for a 2-3 years long postdoctoral position to work with Dr. Andrzej Dragan on the interdisciplinary field of relativistic quantum information. The research is aiming at exploiting relativity to improve quantum information tasks and studying quantum information protocols in the presence of gravity. Candidates must be motivated, confident and creative. They must have a PhD in physics and experience with quantum theory and relativity. Knowledge of quantum information and quantum optics is also desirable.

Description of the research: The research concerns with the theoretical study of the dynamical Casimir and Casimir-Polder effect, in particular the possibility of detecting these effects using Rydberg atoms, which are characterized by high polarizabilities and appropriate transition frequencies. More specifically, we plan to study the dynamics and the excitation probability of Rydberg atoms with high principal quantum number (n>50) trapped near an oscillating plate, or a plate whose refractive index is periodically changed (dynamical mirror).

A theoretical post-doctoral position is available for up to 30 months to investigate the "bad emitter regime" of cavity quantum electrodynamics, with the aim to develop a new generation of quantum devices exploiting decoherence for single photon or indistinguishable photon generation at room temperature. This regime where decoherence mostly affects the quantum emitter and not the optical resonator is completely specific to solid-state artificial atoms and cavities.

A post-doctoral position is available for up to 30 months to develop theoretical approaches in the growing field of thermodynamics of quantum information. The purpose of the work is to suggest and model experiments in close connection with experimental groups, with special emphasis on circuit QED and opto-mechanics of hybrid systems.

Applicants should have brought contributions in one or more of the following areas:
- theory of quantum optics
- theory of circuit QED
- theory of opto-mechanics
- foundations of quantum physics and quantum information

Highly motivated candidates, with a strong research background in theoretical quantum optics, are sought to join a CQT group lead by Dimitris G. Angelakis. The current group consists of four postdocs, two PhD students and a number of visitors. The research to be undertaken lies in the interface of quantum optics, condensed matter and QIP with emphasis in the simulation of quantum many body effects with atomic, photonic and polaritonic systems.

Applications are invited for a Postdoctoral Research Assistant position in the quantum information group of Professor Vlatko Vedral within the Oxford Martin School Programme on Bio-Inspired Quantum (www.oxfordmartin.ox.ac.uk/institutes/quantum). The selected researcher will collaborate with experimental groups within the Oxford Martin School consortium.

We are looking for a suitably qualified, self-driven individual to carry out independent research with focus on non-equilibrium phenomena in open and closed (quantum) systems. This research is part of the ERC Starting Grant 2013 project ESCQUMA that aims at exploring the equilibrium and out-of-equilibrium physics of many-body systems formed by atomic gases of highly excited atoms – so-called Rydberg atoms. The researcher will be an integral part of a team conducting research on this new physical system in search for novel collective phenomena and technological applications.
