October 2017. Weve just returned from a security analysis trip to ITMO university in St. Petersburg. Our lab has previously done informal implementation security audit for commercial quantum cryptosystems from ID Quantique, QuantumCTek, and a prototype at the University of Calgary. Now the Russian subcarrier scheme is added to this list.
April 2017. In a carefully worded announcement, the Government of Canada indicates that Thomas Jenneweins quantum communication demonstrator satellite has been funded. This may make Canada the second country to develop such satellite (Chinas one is already in orbit). Our group has contributed to Thomas project over the past 4 years, and will try to continue doing so.
February 2017. Having single-photon detectors in space is no easy matter: they suffer from radiation in the solar wind, and gradually break down. See our twopreprints on mitigating radiation damage in avalanche photodiodes that should allow them to survive for several years in orbit.
January 2017. Congratulations to our PhD student Shihan Sajeed for winning an IQC achievement award, given for his work on identifying security flaws and loopholes in practical quantum communication systems and protocols.
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.
