A Quick Glance at Quantum Cryptography

Design of low power random number generators for quantum-dot cellular automata

Quantum-dot cellular automata (QCA) are a promising nanotechnology to implement digital circuits at the nanoscale. Devices based on QCA have the advantages of faster speed, lower power consumption, and greatly reduced sizes. In this paper, we are presented the circuits, which generate random numbers in QCA.  Random numbers have many uses in science, art, statistics, cryptography, gaming, gambli...

Free the Quarks

QCD, is the theory of quarks and gluons and their interactions. Its equations are simple enough to fit on the back of an envelope. After a quick glance you might conclude that QCD is not very different from the theory of electricity and magnetism called quantum electrodynamics, or QED, which describes the behavior of electrons — for example, those in the beams within any television set or compu...

The technical newsletter of RSA Laboratories , a division of RSA Data Security

Professor Gilles Brassard, Université de Montréal, is interested in all aspects of cryptology but perhaps his best-known contribution is as a co-developer of Quantum Cryptography. He can be contacted at [email protected]. This essay was written while the author was on sabbatical at the University of Wollongong, Australia. Research supported in part by Canada’s NSERC and Québec’s FCAR. T...
