Review article on entanglement theory
Entanglement is a key resource in quantum information tasks and much effort is being expended in its theoretical and experimental exploration. As a consequence, the quantitative exploration of entanglement as a resource is a central concern of quantum information science. Basic questions such as the characterization, the manipulation, and the quantification of entangled states are addressed in this endeavour. Their answers establish the theory of entanglement and are of interest to theorists and experimentalists alike.
Over the last years the theory of entanglement has grown enormously and many fundamental properties are now well established. Unfortunately, the forest of publications is becoming increasingly dense and frightening for novice and expert alike. QIP IRC partners Martin Plenio and Shashank Virmani from the Institute for Mathematical Sciences at Imperial College http://www.imperial.ac.uk/quantuminformation have recently finished a comprehensive tutorial overview on the subject, presenting the basics and offering many useful explicit formulae.
The article, soon to be published in Quantum Information and Computation, is also available at http://xxx.arxiv.org/abs/quant-ph/0504163
