Quantum Cryptography: from Theory to Practice

Abstract

Quantum cryptography can, in principle, provide unconditional security guaranteed by the law of physics only. Here, we survey the theory and practice of the subject and highlight some recent developments.

Changed the wording to emphasize the importance of using a proper definition of security. 7 pages, prepared for a special issue of "Physics in Canada"
