  • November 2016. Watch video of Vadim’s up-to-date tutorial on security problems in quantum cryptography technology (1 h 31 min) from QCrypt conference.

  • Laser-damaged optical component. Image from article (PDF)  September 2016. Our experimental confirmation of laser-damage attack on two complete systems has been published. Read news on an earlier preprint, and the final journal article (PDF). Watch 12 min talk by Shihan Sajeed about this paper from QCrypt conference.

  • July 2016. Watch video of Vadim’s conference talk “Challenges to physical security of today’s quantum technologies” (35 min).

  • July 2016. “Detector-device-independent” quantum crypto is not secure against attacks on detectors. Watch 11 min talk by Anqi Huang about this paper from QCrypt conference.

  • January 2016. We have shown experimentally that a countermeasure against our blinding attacks by C. C. W. Lim et al. does not work.

  • November 2014. Video lectures by Vadim Makarov introduce you into our field of research. Watch the basics & technology of quantum cryptography (50 min, 2014), or an extended lecture course (about 3 hours, 2014): introduction to quantum cryptography, quantum hacking part 1, quantum hacking part 2. For a more general perspective, see Michele Mosca’s public lecture Cybersecurity in a quantum world: will we be ready?

  • 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.

  • Cover of Phys. Rev. Lett. vol. 112, no. 7 (PDF)  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, see pictures below). 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 lab’s modest contribution to this experiment was to provide special low-noise single-photon detectors, used in Bob on Tenerife. See press about this experiment.

  • June 2012. Vadim Makarov’s lecture on quantum hacking may be a good introduction to this topic, if you have an hour to watch it:
    Table of contents for this video:
    00:00 Introduction to quantum key distribution technology (prior basic knowledge of quantum cryptography is recommended)
    14:26 Introduction to quantum hacking
    21:58 Bugs in random number generator; the need to trust the manufacturer
    30:55 Double clicks
    33:53 Trojan-horse attack
    42:51 Overview of recent attacks
    44:57 Detector attacks; eavesdropping demonstrations; faking the Bell inequality
    1:10:55 Communicating with the manufacturers; countermeasure development
    A similar lecture is given annually at ID Quantique winter school on practical quantum communications.

  • February 2012. Vadim Makarov and the quantum hacking lab have moved from Norway to the Institute for Quantum Computing (IQC), Waterloo, Canada. Our goal is to create the world first security testing and certification facility for quantum cryptographic equipment. During the first year of operation, experiments were housed in the old IQC building (RAC1), while our permanent 70 m2 laboratory in the brand new Quantum-Nano Centre on the campus of the University of Waterloo was awaiting installation of air conditioners, blackout curtains and shelving:
