PhD Studentship in Entanglement between Binary Quantum Systems, University of Sussex, UK

Publish Date: Jul 17, 2015

Deadline: Aug 31, 2015

About PhD Studentships

We are pleased to offer this fully-funded PhD studentship, available in the Department of Physics at the University of Sussex.

Entanglement between binary quantum systems is at the heart of quantum information processing.

In this project, we implement a probabilistic entanglement scheme, which does not require a direct interaction of the ions. The method is based on the entanglement of ions by interference of their fluorescence light. The ions are coupled simultaneously to the same optical cavity. This has the advantage of greatly enhanced collection efficiency of the emitted photons, compared with other schemes which use spontaneous emission in free space. At the same time, the cavity provides interference of amplitudes for photon emission events. To mitigate the effect of limited detection efficiency and detector dark counts we use a novel scheme which relies on the coincident detection of two orthogonally polarised photons.

This approach to pairwise entangle ion in the cavity, it can also be employed to fuse the entangled pairs to form large multi-ion entangled states (cluster states).

The project will be supervised by Dr Matthias Keller. For more information about the project please visit or contact Dr Keller.

Type of award

Postgraduate Research

Award amount

£14057 (2015-16) per annum tax-free bursary and waiver of UK/EU fees each year for 3.5 years. Full-time study


Applicants must hold, or expect to hold, a UK Bachelor degree in Physics at first or upper second class, and/or a UK Master's degree in Physics, or equivalent non-UK qualifications. A good standard of written and spoken English is essential.

The costs covered are for UK and EU student fees only of £4068 p.a. Overseas (ex-EU) students can apply but must have a plan for raising the addition sums required for the higher fees of £17850 p.a

Application procedure

Apply through the Sussex on-line system

State in the Funding Information section of the application form that you would like to apply for this studentship, giving the title of the project as above.

Applications should include a CV, as well as transcripts of marks obtained on your degree(s) and the names and contact details of two academic referees. Please also include a statement explaining your suitability for the project.


Early application is advised. The studentship will be allocated as soon as a suitable candidate is found. The very latest we can accept an application is 31st August 2015, but the position is likely to be filled before this date.

Start date at Sussex: 17th September 2015

First payment of the award bursary: 1st October 2015

Further information

This is a full-time studentship. With agreement of the supervisor the student may take on a limited amount of teaching, for which additional payment will be made.

The award includes an additional training grant of £1250 p.a. for short courses, books, travel, conferences etc.
