- September 2014. Video lectures by Vadim Makarov introduce you into our field of research. You can watch a long lecture course (about 3 hours) filmed in 2014: Introduction to quantum cryptography, Quantum hacking part 1, Quantum hacking part 2. If you dont have three hours, feel free to watch older but shorter (hour-and-something) lecture filmed in 2012.
- September 2014. We congratulate our collaborator Feihu Xu with the Best Student Oral Presentation prize he won at QCrypt 2014. Our group has contributed to the paper he presented at the conference.
- Postdoc position in our group is available. You will primarily do research in our lab, but at the same time be in a very lively quantum information environment consisting of 20+ groups in both theory and experiment. You can also expect higher salary than Canadian average for postdocs. If you have several journal publications in quantum cryptography or closely related field, you may qualify. Contact Vadim.
| ||February 2014. We have shown that security loopholes in quantum communication systems can be created on-demand, by laser damage. Our article is featured in Physics Synopsys, and on the cover of Physical Review Letters. Read the article (PDF).|
- August 2013. Huff... QCrypt the 3rd international conference on quantum cryptography, hosted at IQC this year, is over. It was a heavy task for our institute and our students to house it.
- January 2013. Our laboratory has been the first at the Institute for Quantum Computing to move to the new Mike & Ophelia Lazaridis Quantum-Nano Centre building. We are located in room QNC 3303 (and will relocate to QNC 3301 once additional construction there is complete). We have to say the building is fantastic, and the wait has been worth it.
- September 2012. Quantum teleportation experiment over record 143 km distance has been published in Nature (also available in free preprint). Here you can see
shooting bright green alignment beams at each other. The actual quantum states being teleported are carried by red single photons along the same path, and are invisible to the eye. Our labs modest contribution to this experiment was to provide special low-noise single-photon detectors, used in Bob on Tenerife. See press about this experiment.

The main direction of research for the Quantum hacking lab is testing practical security of quantum communication systems, finding and demonstrating new loopholes, and helping to develop and test countermeasures. For example, quantum cryptography is absolutely secure in theory. However, practical implementations often deviate from the theory description, which leaves loopholes for eavesdropping. By openly publishing all our results, we ensure hardening of quantum communication technology against all possible attacks. This work will also contribute to certification standards for quantum communication equipment.

We also do some single-photon detector development for ultra-long-distance quantum communications, e.g., via satellite.
