David Cory is a physical chemist working to develop quantum devices for sensing and computation. Earlier sensors have found applications in fields as varied as cancer diagnostics, materials processing for tires, improved sensitivity for oil exploration, and a sensor for dark matter searches. Two startups recently spun out of the lab develop quantum sensors with medical, biochemical and materials applications.
He held the Canada Excellence Research Chair in Quantum Information Processing and is currently the principal investigator for the Canada First Research Excellence Fund in Transformative Quantum Technologies.

David Cory and his research team explore the experimental challenges of building small quantum processors. This is a diverse work place with researchers from engineering, science, and math working together. Our quantum processors are based on nuclear spins, electron spins, neutrons, persistent current superconducting devices and optics. Most experiments involve the use of hybrid systems composed of several types of quantum bits in an effort to push overall performance. A common theme in our studies is to engineer efficient, high fidelity, coherent control of open quantum systems.
David Cory teaches both undergraduate and graduate courses. Course offerings have included topics in quantum information processing and quantum mechanics.
