The Quantum Internet Systems Lab
Transporting quantum information across Canada...
The Quantum Internet Systems Laboratory advances next-generation technologies for quantum communication and quantum cryptography. Our research explores both applied and fundamental aspects of quantum photonics and quantum optics.
What We Do
The Quantum Internet Systems Lab studies practical quantum photonics and quantum optics solutions to address real-world challenges. By merging cutting-edge information technologies with the principles of quantum physics, our team builds advanced quantum networking infrastructure and tools that strengthen the security and reliability of quantum networks, with a vision of enabling global quantum communications.
Research Activities
- Vancouver Quantum Networking testbed (Q-Van), studying quantum secure communications, quantum networked qubits and entanglement distribution over deployed fibre, free-space and satellites.
- Designing and experimentally demonstrating quantum photonic devices for advanced communication and computing.
- Advancing ultra-long-distance quantum communication systems through terrestrial, HAP, and satellite technologies.
- Developing entangled photon sources for various quantum protocols.

Past Research Highlights
- Mission white-paper for QEYSSat 2.0 - to achieve quantum teleportation accross Canada (CJP2024).
- QKD with an airborne quantum receiver (QST 2017).
- Physics World Top Ten results of 2017 for the demonstration of three-photon quantum interferences.
- Heralding of single photons (PRL 2015).
- Pioneering direct generation of three photon entangled states from cascaded parametric down conversion. (Nature 2010) Which led to the direct generation of three-photon entanglement in:
- energy-time (Nature Physics 2012)
- and polarization GHZ (Nature Photonics 2024)
- and Fransen-type interference (PRL 2017).
- Proposal for quantum enhanced telescopes (PRL 2012).
Our group is also part of the Institute for Quantum Computing, University of Waterloo.
