Spotlight on quantum cryptography

(Nanowerk News) A guest editor on a recent issue of the New Journal of Physics, the Institute for Quantum Computing’s (IQC) Norbert Lütkenhaus explored the recent developments in quantum cryptography technology in an editorial written jointly with Andrew Shields (Toshiba Research).
Quantum cryptography and quantum key distribution (QKD) technologies are becoming more widely secured tools for cryptographic services. Recent developments have uncovered a substantial increase in the secure bit rate of QKD, and its extension to ever longer fibre- and air-based links and the emergence of metro-scale trusted networks. Numerous start-ups and recognized companies are further exploring this field with the objective of global-scale communications using quantum repeaters or Earth-satellite links.
Currently, IQC has a strong active group in QKD technologies at its location at the University of Waterloo that offers a unique opportunity to link researchers with internationally leading expertise in classical cryptography, and in experimental and theoretical quantum cryptography. IQC is therefore one of the world-wide leading research centres serving as a contact point to industrial partners who hold interest in quantum technology.
The full editorial, "Focus on Quantum Cryptography: Theory and Practice" is available on the New Journal of Physics website.
