Entanglement, in which two quantum systems can exhibit correlations that are greater than the limit allowed by classical physics, is one of the most intriguing predictions of quantum mechanics. Entanglement between remote atoms or ions is a key resource for quantum computing, and plays a central role in the proposed NQIT Q20:20 machine.
We propose two schemes for entangling remote atoms: one probabilistic and one deterministic. In the probabilistic scheme, two distant atoms each emit a photon which are combined at the two input ports of a 50:50 beamsplitter. If the photons are detected at different output ports, then the atoms are projected into an entangled state. In place of a simple beam splitter, we also anticipate using more complex photonic networks [A. Holleczek, PRL 117, 023602 (2016)] in combination with active optical photon switching and routing. In the deterministic scheme, an atom emits a single photon which is reabsorbed by a second atom by running the emission process in reverse [J. Dilley, PRA 85, 023834 (2012)]. In doing so, the state of the first atom is entangled with that of the second. In both schemes, a high-finesse optical cavity is used to enhance the light-atom interactions.
Currently, we have two optical cavity experiments with random atom loading. The first phase of the project will be to build an optical dipole trap to permanently hold single atoms in the cavities. The feasibility of this approach has recently been demonstrated [D. Stuart, arXiv:1708.06672], and suitable fibre-tip and FIB-milled cavity mirrors are at present under development. The second phase will be to generate and quantify the entanglement between the two remote atoms using full Bell-state tomography.
This is a highly challenging experimental project which will push the limits of laser and optical technology. It would suit a student with experience in atomic and laser physics and a keen interest in exploring quantum phenomena experimentally. EPSRC eligibility criteria apply for this project, therefore only UK students witha funding status of "Home" are eligible for the position.
The research team of Dr Kuhn does encompass two postdocs and four graduate students which operate three laboratories dedicated to cavity-qed and atom-photon coupling in cavities at the Physics department of the University of Oxford. The work space is well equipped, comprising four vacuum chambers for studying atom-photon coupling in cavities, a large number of ECDL and fibre lasers for atom manipulation, a frequency comb for synchronously stabilising all laser and cavity frequencies, and a large battery of single-photon counters. The project builds on the current work by other graduate students in our group, atom-cavity coupling and strong cavity coupling.
The new student will directly contribute towards achieving cavity-mediated remote entanglement. The deterministic entanglement scheme will be done in close collaboration with Almut Beige’s theory group in Leeds, who have developed a complete quantum description of the field inside a cavity, as well as devised cavity-cavity coupling protocols. All necessary apparatus exists within NQIT, including high-finesse cavities, vacuum chambers, and all necessary lasers for trapping and driving the photon production process. Close support on a day-to-day basis will be provided by at least one Oxford PDRA for the duration of the project.

A maternity cover position is available for an experienced communications expert who is keen to lead the communications strategy for a high profile flagship research project led by the University of Oxford.
The size and complexity of this strategically critical award presents a rare opportunity for someone looking to embrace fast moving communications challenges in a world leading research environment, together with management of a wide and varied programme of internal and public facing events. Effective communication with consortium members, partners, stakeholders and the public is crucial to the Hub’s mission and this role is vital to the delivery of these objectives.
The Networked Quantum Information Technology Hub (NQIT) Hub builds on the world’s most advanced quantum technologies to develop practical technologies in entirely new sectors. It is funded by a £38m grant awarded to a consortium of nine universities and is supported by a number of commercial and governmental partners. As part of EPSRC’s £270m National Quantum Technologies Programme, the Hub has an international profile and corresponding responsibilities to achieve the highest levels of success. More information can be found at nqit.ox.ac.uk.
Applicants should either possess a sciences degree or evidence of the ability to engage rapidly and effectively with unfamiliar technical material. Understanding of quantum information and previous experience of working in a university environment are not essential as this role also has an industry focus. However, excellent communication skills gained with a variety of media and evidence of successful oral and written presentation of technical material are essential. Candidates will be expected to have demonstrable experience in the ability to liaise effectively with wide range of people including the general public, internal staff, industrial collaborators and funding agencies.
Please direct enquiries about the role to Frances Sweeney (firstname.lastname@example.org).

An NQIT EPSRC DTP Studentship is available working in the Photonic Nanomaterials Group in the Department of Materials, University of Oxford, supervised by Professor Jason Smith.
This project will involve coupling diamond colour centres in single crystal membranes into optical microcavities to build efficient interfaces between coherent spin states and an optical network.
Our apparatus is now at the stage where we have demonstrated the first cavity-enhanced photon emission from a zero phonon line of a nitrogen vacancy centre in a diamond membrane. Further work is required to improve the quality of the colour centres in the membranes. The project will involve investigation of NV centres in membranes of different crystal orientations and using different material growth conditions.
Please contact Professor Jason Smith for more information.
