SECURITY OF QUANTUM KEY DISTRIBUTION [PDF]
International Journal of Quantum Information, 2008 Quantum Information Theory is an area of physics which studies both fundamental and applied issues in quantum mechanics from an information-theoretical viewpoint. The underlying techniques are, however, often restricted to the analysis of systems which satisfy a certain independence condition.
