Quantum cryptography is arguably the fastest growing area in quantum information science.
Novel theoretical protocols are designed on a regular basis, security proofs are constantly …

In principle, quantum key distribution (QKD) offers information-theoretic security based on
the laws of physics. In practice, however, the imperfections of realistic devices might …

Finally, here is a modern, self-contained text on quantum information theory suitable for
graduate-level courses. Develo** the subject'from the ground up'it covers classical results …

All our former experience with application of quantum theory seems to say that what is
predicted by quantum formalism must occur in the laboratory. But the essence of quantum …

One of the best signatures of nonclassicality in a quantum system is the existence of
correlations that have no classical counterpart. Different methods for quantifying the …

Quantum cryptography exploits principles of quantum physics for the secure processing of
information. A prominent example is secure communication, ie, the task of transmitting …

We review the theory of entanglement measures, concentrating mostly on the finite
dimensional two-party case. Topics covered include: single-copy and asymptotic …

Quantum Information Theory is an area of physics which studies both fundamental and
applied issues in quantum mechanics from an information-theoretical viewpoint. The …

Heisenberg's uncertainty principle forms a fundamental element of quantum mechanics.
Uncertainty relations in terms of entropies were initially proposed to deal with conceptual …

The uncertainty principle, originally formulated by Heisenberg, clearly illustrates the
difference between classical and quantum mechanics. The principle bounds the …
