Atom-photon interfaces for fibres and photonic chips

Efficient atom photon interfaces are the basis for quantum computers, fibre networks or miniaturised quantum sensors. Photons are ideal systems to create entangled states or to carry quantum information, while atoms are well suited for information storage or to mediate interactions between photons.

We are looking for a highly motivated and talented PhD student willing to join the QCAT Quantum Technologies Research Group led by Dr. habil. Magdalena Stobinska and her team undertaking the research project entitled “Integrated optics in time-frequency domain: a new versatile platform for quantum technologies”, funded by the Foundation for Polish Science. It aims at research in the field of theoretical condensed matter as well as theoretical and experimental quantum optics.

We are seeking two talented and motivated PhD students to work in the field of quantum information theory in the group led by Remigiusz Augusiak. These positions will be based at the Center for Theoretical Physics of the Polish Academy of Sciences in Warsaw (Poland) and are funded by the Foundation for Polish Science within the First Team programme.

These are two scholarships to start preferably from June 2018.

Closing date: 17 May 2018. Selected applicants will be invited for an interview which will be held either at the institute or via Skype.

Currently we have open one Postdoctoral fellow position and two PhD positions.

STOCKHOLM UNIVERSITY, DEPARTMENT OF PHYSICS

We are searching for a talented and motivated PhD student who is interested in experimental quantum optics and quantum information with trapped ions. The research will focus on the investigation of trapped strontium Rydberg ions.

Trapped Rydberg ions are a novel system for quantum technologies. By laser light, the ions’ outermost electrons are excited to high-lying orbitals. Such Rydberg ions are million times bigger than ions in the ground state, and due to their size, they obtain very peculiar properties.

Candidates are sought for a PhD position in Theoretical Physics at l'Institut de Nanosciences de Paris (Sorbonne université) to be supervised by Dr Alex Chin. The project involves the simulation and theory of open quantum systems, with a focus on using new Tensor Network methods as a way to access the non-perturbative, real-time physics of excitons interacting with molecular vibrations in organic semiconductors and supramolecular nanostructures (see pdf at URL above).

There are different deadlines for each of the positions

Multiphoton quantum interference is one of the most intriguing phenomena in quantum physics, and is at the very heart of quantum computing and metrology technologies. However, the post-classical sensing and computational capabilities of multiphoton networks are yet far from being fully explored in practical experimental scenarios.

This theoretical project aims to develop scalable sensing and computational techniques based on the use of optimal linear interferometers with experimentally available photonic input states. The main idea is to exploit the full quantum information encoded in the interferometric evolution of the input photonic quantum states by employing novel measurement techniques (e.g. iterative interferometric dynamics, conditional dynamics, multiplexing and correlation measurements sensitive to the photonic inner and spatial modes).

Start date: 1 October 2018 or 1 February 2019
Application deadline: 7 May 2018
Supervisors: Dr V Tamma, Dr H Yu (Univeresity of Portsmouth), Prof G Adesso (University of Nottingham)
