Dr. Cory is Professor of Chemistry at the University of Waterloo and researcher with the university's Institute for Quantum Computing. He is the CERC's chair in Quantum Information Processing. He is an experimental physicist working to develop spin-based quantum processors.

Research Interests

The aim of our group is to design, fabricate, and deploy quantum devices. We look to make quantum sensors and actuators that are coherent, controllable and have practical applications. To achieve this we explore hybrid quantum technologies that combine electron and nuclear spin with transport, optics and superconducting systems. Near term applications are focused on achieving molecule magnetic resonance spectroscopy of molecularly thick films.

The program demands advances in the theory and practice of coherent control. In particular we are interested in efficiently characterizing errors and then correcting/avoiding them. A new avenue is to gain an understanding of systems engineering in the quantum setting. This is essential for integrating our quantum devices into more complex systems.

The work is split between PI, IQC (where most of the labs are) and NIST (where we are building a quantum information theory enhanced neutron interferometer lab).
