Quantum CryptographyAt Los Alamos we have rather a different perspective - in some ways - to those working in a strictly university environment. We have to do things that are more application oriented in the long run, and quantum cryptography is an application that, at least from the point of view of physics, is feasible today.

Introductionogies. If an atom is used as a physical bit then quantum mechanics shows that apart from the two distinct electronic states the atom can be also prepared in a coherent superposition of the two states. This means that the atom is both in state 0 . state 1. In general, a quantum two-state system, call

The Role of Europeeen shared between work in Europe and USA. Experimental work has developed in the 1990s in parallel in USA and Europe, with significant teams in the USA, for example at Los Alamos and MIT, but with centres of experimental and theoretical work developing in Europe at, for example, Geneva, Innsbruck,
