Hoi-Kwong Lo received his Ph.D. in Physics from Caltech in 1994. After working at the Institute for Advanced Study, Princeton, Hewlett-Packard Labs, Bristol, UK and MagiQ Technologies, Inc., New York, NY, he joined the University of Toronto as an Associate Professor in Department of Electrical and Computer Engineering and the Department of Physics in 2002 and was promoted to Full Professorship in 2009. He moved to the Physics Department of NUS in 2025 as a Professor of Physics and Provost’s Chair Professor (2025-2028).
He is a Fellow of the American Physical Society, an Optica Fellow, and an IEEE Fellow. He has won various awards including the CAP-INO Medal for Outstanding Achievement in Applied Photonics (2022), the IEEE Photonics Society Quantum Electronics Award (2023), and the QCMC International Quantum Award (2024).

Hoi Kwong Lo Group
Our long-term goal is to build the future quantum internet. The Quantum Internet will allow secure communication with information-theoretic security, scaling quantum computing power, clock synchronization and distributed quantum sensing, among other applications. With the rise of quantum computing, the Quantum Internet is an indispensable category of quantum technologies.
More concretely, we work on the theory and experiment of quantum communication, quantum networks and quantum cryptography. Our medium-term goals include building novel quantum networks with untrusted relays, finding side-channels and mitigation techniques, building quantum repeater graph states towards the quantum internet, and using photonics graph states for quantum sensing and quantum computing.
We are seeking highly motivated Ph.D. students, Research Fellows and Senior Research Fellows to join our team. If you are interested, please visit https://www.physics.nus.edu.sg/faculty/lo-hoi-kwong/ or contact Hoi-Kwong directly.
