Key research interests:

Tim Spiller is a Technical Consultant in the HP Labs Mathematics, Cryptography and Security Research group. His main QIPC research interest is quantum hardware theory, examples being superconducting circuits, magnetic systems and electrons on superfluid helium. Other related interests include quantum trajectories and general quantum phenomena in condensed matter systems.

Adrian Kent is a Visiting Academic Researcher in the HP Labs Mathematics, Cryptography and Security Research group, on leave from a Royal Society University Research Fellowship at DAMTP, University of Cambridge. His research covers a broad area from the foundations of quantum theory and quantum information theory to devising new unconditionally secure cryptographic protocols and other technological applications. A major current interest is developing a more systematic understanding of quantum cryptography and of relativistic cryptography; that is, characterising the cryptographic tasks which can be implemented securely by relying on quantum theory, special relativity, or both.

William Munro is a research engineer within the HP Labs Mathematics, Cryptography and Security group. His interest covers a range of topics from quantum hardware theory (in particular solid state and optical implementations), quantum communication and cryptography through to the foundational tests of quantum theory. His current interests include: quantum tomography (an essential reconstruction tool for a few qubit quantum computer), decoherence free spaces and their application to practical QIP as well as multiparticle tests of quantum mechanics.
