APTF (titular Full Professor)
I am Professor of Physics, working within the Department of Atomic and Laser Physics on Nuclear Magnetic Resonance (NMR) Quantum Computation, and Fellow and Tutor in Physics at Brasenose College. I originally studied Chemistry at Oxford, and have also studied applications of NMR in Chemistry and Biochemistry. In 1997 I switched to Physics, performing the first NMR implementation of a quantum algorithm, and have remained largely in this area ever since.
My research is principally concerned with the implementation of small quantum computers using nuclear magnetic resonance (NMR) techniques. I currently have a special interest in developing logic gates which are robust against systematic hardware errors, using the ideas of composite and shaped pulses developed in NMR. Previously I have worked on applications of geometric phases to robust logic, the use of para-hydrogen to prepare pure spin states in NMR experiments, and the use of ideas from quantum cellular automata to implement quantum information processing in systems with only limited control.
Beyond this I have a historic interest in the development of NMR techniques to study chemical and biochemical systems. More recently I have been interested in the use of ideas from quantum information processing to understand spin-sensing chemical reactions.
I am currently Head of Teaching within the Physics Department, and as such am ultimately responsible for coordinating all departmental teaching and teaching support, although many day-to-day matters are delegated.
I lecture the first year optics course and part of the fourth year advanced option paper on quantum information processing, which I was originally responsible for coordinating. I was previously head of the first year electronics teaching lab. At Brasenose College I give tutorials in first year mechanics and relativity, second year quantum mechanics, and third year atomic physics, as well as coordinating all other college teaching in physics as well as admissions and general oversight of the subject.
Within the department I have taken a special interest in admissions, and was largely responsible for designing the current admissions process. In my college I took a special interest in investment policy and governance reform. I have also been a member of the Steering Committee of Conference of Colleges.
For although light oftenest behaves as a wave, it can be looked on as a mote, the "lightbit". We have already said by the way that a mote of stuff can behave not only as a chunk, but as a wave. Down among the unclefts, things do not happen in steady flowings, but in leaps between bestandings that are not forbidden. The knowledge-hunt of this is called "lump beholding".
