Quantum information theory is currently a rapidly developing, high profile cross-disciplinary field. This proposal is directed towards the development of fundamental theoretical properties of quantum information which underlie many aspects of quantum communication and quantum computation.We will study the compressibility properties of sources of mixed quantum states and relationships between classical and quantum information resources. A recent resurgence of international effort on these questions has produced some breakthroughs (by the PI and others) especially a new approach by Koashi and Imoto, relating these questions to a fundamental study of state transformations. The optimal compression of pure quantum states has been largely understood since 1995 but the case of mixed states remains unresolved. We plan to develop these initiatives building on our substantial existing work. We will extend these ideas to further areas such as multiple source coding and wider applications of a study of allowable quantum state transformations.The breakthroughs above took place in 2000 and 2001 so this proposal has an urgent timeliness. The PI is uniquely placed to take advantage of these developments in view of his seminal work in the area and recent contributions.
