We thank Constantin Brif;
Jon Dowling;
Steven van Enk;
Jeff Kimble;
Alesha Kitaev;
and Kip Thorne for instructive discussions about quantum measurement. We are especially grateful to Hideo Mabuchi for introducing us to this fascinating subject;
to Chris Fuchs for sharing his insights into state distinguishability;
and to Dave Beckman for discussions on improving the superdense coding method by applying a driving field. Thanks to Barry Simon for useful comments on the theorem in Appendix A;
and for persuading us that it is not completely trivial. We also thank C. Woodward for helpful correspondence. A. M. C. and J. R. received support from Caltech’s Summer Undergraduate Research Fellowship (SURF) programme;
and A. M. C. received a fellowship endowed by Arthur R. Adams. This work has been supported in part by the Department of Energy under Grant No. DE-FG03-92-ER40701;
and by DARPA through the Quantum Information and Computation (QUIC) project administered by the Army Research Office under Grant No. DAAH04-96-1-0386;
