Abstract
I consider some promising future directions for quantum information theory that could influence the development of 21st century physics. Advances in the theory of the distinguishability of superoperators may lead to new strategies for improving the precision of quantum-limited measurements. A better grasp of the properties of multi-partite quantum entanglement may lead to deeper understanding of strongly-coupled dynamics in quantum many-body systems, quantum field theory, and quantum gravity.

© 2000 Taylor & Francis Ltd. Received 7 April 1999. Available online: 03 Jul 2009. My work on the applications of quantum information theory to quantum-limited measurements has been in collaboration with Andrew Childs and Joe Renes [6]. I'm very grateful to Hideo Mabuchi for stimulating my interest in that subject, and to Dave Beckman and Chris Fuchs for their helpful suggestions. I have also benefitted from discussions about precision measurement with Constantin Brif, Jon Dowling, Steven van Enk, Jeff Kimble, Alesha Kitaev, and Kip Thorne. I thank Michael Nielsen for emphasizing the relevance of quantum information in quantum critical phenomena, Ian Affleck for enlightening correspondence about conformal field theory, Anton Kapustin for a discussion about Ref. [37], Dorje Brody for informing me about Ref. [35], and Curt Callan for encouragement. Finally, I am indebted to Ike Chuang for challenging me to speculate about the future of quantum information theory.
