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.
Further details from Dr Axel Kuhn.
We are pleased to announce the opening of a full-time post-doctoral position at Oxford University as part of the EPSRC-funded Networked Quantum Information Technologies (NQIT) Hub. The aim of the Hub is to take some of the UK’s world-leading experimental work in ion traps and photonic networks and translate it into quantum computing technology through a highly ambitious and multidisciplinary programme.
The role is within the theory group of Dr Jonathan Barrett, focusing on the areas of small-scale quantum computing, secure communications, and the verification of quantum technology. The research includes the development of algorithms that can run on a small-scale quantum device, protocols for verifying that a quantum device is behaving as advertised even when held by an adversary, and/or device-independent protocols for cryptographic tasks such as key distribution and randomness generation. The work will support the overall theory, design, and applications development for quantum computing systems developed within the NQIT hub.
You will have, or shortly be expecting to obtain, a doctoral degree in Computer Science, Physics, Mathematics, or a related discipline. You should also have a proven record of research, including strong publications, in at least one of the areas of quantum communication, quantum cryptography or quantum algorithms; a willingness to collaborate with experimental groups; excellent scientific writing ability and good communication skills; willingness to travel internationally.
The post is fixed-term until 30 November 2019.
The closing date for applications is 12 noon on 11 April 2018

The project unites two distinct areas of quantum information processing, single ions stored in radiofrequency traps, and single photons in optical fibres. In both fields, there have been spectacular advances recently. Strings of ions are presently the most successful implementation of quantum computing, with elementary quantum algorithms and quantum simulations realized. Photons are used to distribute entanglement over ever increasing distances. The principal challenge in the field is to enhance quantum processing power by scaling up current devices to larger quantum systems. We are pursuing the of the most promising strategies, distributed quantum computation, in which multiple small-scale ion processors are interlinked by exchanging photonic quantum bits via optical fibres. It requires an efficient quantum interface between ions and photons, mapping ionic to photonic quantum states and vice versa. To maximise fidelity and the success rate of the scheme, the interaction of ions and photons must take place in an optical cavity with high finesse, a technology in which the Ion Trap Cavity-QED and Molecular Physics group in Sussex has a leading role.
The aim of this project is to investigate, optimise and evaluate schemes to generate entangled states between trapped ions and photons in different implementations such as polarisation, time bin or phase decoding. For this, cavity assisted Raman transitions will be employed to transfer the ion’s state onto the photon in a deterministic way. The project is mainly experimental and will be conducted in the research labs in Sussex, the theoretical study of the schemes and possible developments of novel schemes will be pursued in collaboration with Peter Horak, University of Southampton.

We recently invented a method quantum gates with trapped ions are executed by the application of voltages to a microchip in the presence of a few global radiation fields analogous to the operation of transistors in a classical computer. We have already accomplished two-qubit quantum gates with fidelities close to the fault-tolerant threshold. We are now working towards increasing two-qubit gate fidelities above 99.9% and reduce gate times down between 10 - 100 μs. In order to achieve that, we are raising magnetic field gradients on the chip while increasing parameter fluctuation resilience and resilience to noise via a number of coherent control methods such as double dressing. We are also developing subsystems for this purpose such as stable voltage sources, microwave amplification and current sources together with industrial collaborators. The aim of this project is to combine the work of our industry collaborators with coherent control methods to obtain ultimate gate fidelities and gate speeds.

We are looking for a Postdoctoral Research Assistant in the Predictability of Weather and Climate group within the sub-Department of Atmospheric, Oceanic and Planetary Physics (AOPP). The post will be available for three years from Jan 1st 2018.
This post fits within a general research programme developing imprecise weather and climate models. In particular, the post will complement and extend a European Research Council Advanced grant trying to estimate the information content in the hundreds of millions of variables in a weather forecast model. By restricting data transport inside a computer to the bits that contain real information, it is hoped to be able to develop much more efficient numerical weather and climate models.
More specifically, we are looking for a postdoctoral researcher who can explore the notion of imprecise computing for weather and climate related code in one of two possible types of innovative computing hardware:
- Field Programmable Gate Array (FPGA) computers
- Noisy quantum computers
For either of these, it is not necessary that the applicant has a knowledge of weather or climate model code.
For the FPGA work we will be seeking to extend the work of Duben et al (2015) and Jeffress et al (2017):
to study the implementation in hardware of arbitrarily reduced precision in simplified weather\climate models.
For the quantum computing work, we will be taking an even more idealised and exploratory approach – are there any situations where noisy quantum computers could be utilised in finding approximate solutions to the types of calculation used in a weather or climate model? Are there situations where these approximate solutions could have some value?

Applications are invited for a Postdoctoral Research Assistant in Ion Trap Quantum Computing. The post is available initially for a fixed-term duration of 2 years, with the possibility of extension depending on funding.
Oxford is leading a multi-institution £38M EPSRC-funded “Hub” for Networked Quantum Information Technologies (www.nqit.ox.ac.uk). A central goal of this 5-year project is the development of a small prototype quantum information processor, consisting of trapped-ion qubits linked by photonic interconnects. The Oxford Ion Trap QC group has recently demonstrated the longest-lived single-qubit memory, the most precise single-shot qubit readout, and the highest-fidelity single- and two-qubit quantum logic gates, in any physical system, with all these elementary operations significantly surpassing recent estimates of the quantum computing “fault-tolerant threshold”.
We seek highly-motivated and technically-skilled individuals to join the team which is building the prototype device. As well as driving forward the development of this complex ion trap quantum network, duties will include preparing reports, presentations and scientific papers, and assisting with the supervision of graduate students.
Applicants should possess, or be close to obtaining a doctorate in physics or a related field and ideally a strong background in experimental quantum optics or atomic physics.
Previous experience in the field of ion or atom trapping will be highly desirable.
Candidates will be expected to demonstrate a good understanding of the relevant basic theory, skills in data analysis and numerical modelling, and a strong research track record.
The postholder will have the opportunity to teach.
Please direct enquiries about the role to Dr David Lucas (firstname.lastname@example.org).
