Patrick did his PhD at the University of California, Berkeley on the topic of optically induced alignment of electron and nuclear spins in semiconductors. Subsequently, he switched fields to quantum foundations and quantum information theory in his postdoctoral research with Robert Griffiths at Carnegie Mellon University. He continued along these lines while working with Stephanie Wehner at the National University of Singapore. Patrick’s research in Singapore especially focused on entropic formulations of Heisenberg’s uncertainty principle, and how such formulations relate to wave-particle duality in interferometers. A representative publication can be found at:
Patrick’s current research at Waterloo focuses on the security of quantum key distribution (QKD). He is currently developing a numerical approach for calculating secret key rates that is both efficient (computationally fast) as well as robust, in the sense that it can handle arbitrary QKD protocols even with device imperfections. The ultimate aim of this project is to develop a user-friendly software that will allow researchers to easily explore novel protocol ideas and analyze their performance. See http://arxiv.org/abs/1510.01294 for more details on this project.
