The Quantum Chernoff Bound
K. M. R. Audenaert, J. Calsamiglia, Ll. Masanes +4
We consider the problem of discriminating two different quantum states in the setting of asymptotically many copies, and determine the optimal strategy that minimizes the total pro…
Optimal discrimination of mixed states: the quantum Chernoff bound
J. Calsamiglia, Ll. Masanes, R. Munoz-Tapia +2
This paper has been withdrawn by the authors, due to a flaw in the proof of Theorem 1. This preprint is superseded by quant-ph/0610027, where a correct proof can be found. Thanks t…
How to hide a secret direction
E. Bagan, J. Calsamiglia, R. Demkowicz-Dobrzanski +1
We present a procedure to share a secret spatial direction in the absence of a common reference frame using a multipartite quantum state. The procedure guarantees that the parties…
