I am now a Professor of Quantum Technology at the University of Strathclyde, based in Physics having rejoined the Computational Nonlinear & Quantum Optics group on 1st Nov 2021.

I am researching into many aspects of quantum computation, from understanding how the quantum speed up is achieved to comparisons of analog and digital versions of quantum computers. Much of my work involves classical numerical simulation, calculating the entanglement in quantum registers and investigating the properties of quantum versions of random walks.

If you want to know more specifically what I do you can search for my papers on the preprint arXiv or ORCID listing or Google Scholar.

The Collaborative Computational Project on Quantum Computing (CCP-QC) is a network to bring together computational scientists with experts in quantum computing. Please join the mailing list if you are interested.

I also lead an ExCALIBUR cross-cutting project QEVEC on integrating quantum and high performance computing.

My talk from QSQW 2020 is now online: How to compute with quantum walks also downloadable, slides, and properly catalogued (DOI) in the CIRM library. Links to more of my talks online here.

Along with Sir Peter Knight FRS and Professor Andrew Daley, I organised a Royal Society Theo Murphy international scientific meeting: Continuous-time quantum computing and simulation: perspectives and challenges 2-3 October 2019 at the Kavli Royal Society Centre, Chicheley Hall.

My foundations of computer science work can be explored in an edited special issue on Heterotic Computing published online in Phil. Trans. Roy. Soc. A. You can read a blog post with more information. A related paper is available open access in Proc. Roy. Soc. A - When does a physical system compute?

From 2014 to 2021 I was a Reader in Computational Quantum Information Theory at Durham University in the Quantum Light and Matter Research Section in the Department of Physics, and the Joint Quantum Centre (Durham and Newcastle), funded under the EPSRC Quantum Technologies theme by an EPSRC Established Career Fellowship in Hybrid Quantum-Classical Computation (Aug 2014 - Jul 2019).

From 2004 to 2014, I was in the School of Physics and Astronomy at the University of Leeds in the (former) Quantum Information group. I was funded by a Royal Society University Research Fellowship until September 2012, and promoted to Reader in Quantum Computational Physics in 2011.

Before this I was part of the Quantum Information and Quantum Optics Theory Group at Imperial College. My colleagues there are almost normal people... Before coming to Imperial (April 2000), I was in the Computational Nonlinear & Quantum Optics group at Strathclyde University working on quantum measurement.

I finished my PhD at Edinburgh in July 1999, in the Soft condensed matter group. It was an investigation of the basic dynamics of phase separation when a binary fluid mixture is quenched to region where the two fluids prefer to be separated - spinodal decomposition. For more details, you can read a poster that I prepared for the MolSim 99 online conference (April 1999).

Before my PhD, I used to work for GreenNet, a non-profit Internet service provider (now over thirty years old!) and member the Association for Progressive Communications. I have also done work for Oxfam and Amnesty International. Prior to joining GreenNet I lived in Glasgow and was an active campaigner for Scottish CND.

I have a fine gallery of photos and links to photos from various holidays, conferences, trips, hill-walks etc. (click to enlarge; link leads to past photo of the moment)

If you are looking for the old web pages of the 15th UK and European Meeting on the Foundations of Physics
I rescued them and put them here. Note that recordings of some of the talks are still available on the website. -->
