Aephraim M. Steinberg

Aephraim M. Steinberg is a University Professor in the Department of Physics at the University of Toronto, affiliated with the Faculty of Arts and Science. He leads the Quantum Optics Group and is a Senior Fellow of the Canadian Institute for Advanced Research (CIFAR), co-directing its Quantum Information Science program. His research focuses on experimental quantum mechanics, quantum measurement, and quantum information processing, with contributions to foundational questions in quantum theory and applications in quantum technologies.

Education: B.S. from Yale University (1988), Ph.D. from UC Berkeley (1994). Postdoctoral fellowships include the Chateaubriand Fellowship at Université de Paris VI (1994) and NRC Fellowship at NIST (1995–96).

Research Interests: Experimental studies of quantum foundations, including weak measurement, tunneling times, and quantum paradoxes. Develops technologies for quantum information, such as entangled photon sources and quantum metrology. Explores ultracold atoms, Bose-Einstein condensates, and light-matter interactions at the quantum level.

Awards: APS Doctoral Thesis Prize (1996), Polanyi Prize (1997), Herzberg Medal (2006), Rutherford Medal (2006), Royal Society of Canada Fellowship (2016). Fellowships from OSA, APS, and IOP.

Grants & Collaborations: Funded by NSERC, CIFAR, FQXi, and DARPA. Collaborates with institutions worldwide, including Perimeter Institute, Institut d'Optique, and Laboratoire Kastler-Brossel.

Labs & Teams: Directs the Quantum Optics Group at U of T, contributing to the Center for Quantum Information and Quantum Control (CQIQC). Hosts a dynamic team of graduate students, postdocs, and international visitors.
