Recycling of quantum information: Multiple observations of quantum systems
Peter Rapcan, John Calsamiglia, Ramon Munoz-Tapia +2
Given a finite number of copies of an unknown qubit state that have already been measured optimally, can one still extract any information about the original unknown state? We give…

The quantum Chernoff bound as a measure of distinguishability between density matrices: application to qubit and Gaussian states
J. Calsamiglia, R. Munoz-Tapia, Ll. Masanes +2
Hypothesis testing is a fundamental issue in statistical inference and has been a crucial element in the development of information sciences. The Chernoff bound gives the minimal B…
