Lars Lydersen

Biography

Lars Lydersen has a masters degree in electrical engineering and a PhD from the Norwegian University of Science and Technology. During his masters degree he studied 6 months at TU Delft. The PhD is titled "Practical security of quantum cryptography", and contains severeal both theoretical and experimental publications releated to imperfections in implementations of quantum cryptography. Most notably, the findings of security loopholes in two commercial quantum cryptography systems were published in Nature Photonics.

Presentation: Quantum cryptography and quantum hacking

In theory, quantum cryptography offers perfect security. However, in reality, implementations must use imperfect components. This may cause security loopholes in the implementation. Here we present the basic principles of quantum cryptography, and the current status of the search for implementation caused security loopholes.
