Quantum optical signal states that exhibit Heisenberg’s uncertainty principle, such as coherent and squeezed states, have many applications in communications, computation, sensing and metrology. The Experimental Quantum Communications Group at the Department of Physics, Univeristy of York is carrying out work on coherent optical signals for quantum communications, over optical fibre and free-space channels, for the generation of unconditionally secure keys for cryptographic purposes. Despite many advantages over single-photon based communications, such as tolerance to spurious photonic noise, current research in quantum coherent communication is limited in reach to distances of a few hundred kilometers, and to low detection bandwidth of a few hundred MHz. This PhD project is seeking to address these limitations.
We are seeking a PhD candidate with suitable undergraduate training in physics, engineering, computer science or related subjects who are keen to research experimental aspects of quantum coherent communications. They will be working on improving both the current transmission distance as well as detection bandwidth limit of quantum coherent communication, primarily for free-space channels such as satellite-to-ground, but also for long-distance fibre channels.
The successful applicant will be part of a vibrant team of experimentalists with skills and expertise ranging from quantum information, quantum communication, quantum optics, electronics, programming, networking, hardware and software development, etc.
This studentship is experimental, and therefore will be primarily lab-based. However, some theoretical analysis, as well as simulation studies will be required in support of the experimental research. This position will be based at the University of York, with opportunities to support field-trials and pilots in other parts of the UK.
This fully-funded studentship is available immediately and will be kept open until filled. For informal enquiries please contact Dr. Rupesh Kumar ([Email Address Removed])
