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This paper has been withdrawn by the authors, due to a flaw in the proof of Theorem 1. This preprint is superseded by quant-ph/0610027, where a correct proof can be found.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…
Secrecy extraction from no-signalling correlations
Valerio Scarani, Nicolas Gisin, Nicolas Brunner +3
Quantum cryptography shows that one can guarantee the secrecy of correlation on the sole basis of the laws of physics, that is without limiting the computational power of the eaves…
Key Distillation and the Secret-Bit Fraction
Nick S. Jones, Lluis Masanes
We consider distillation of secret bits from partially secret noisy correlations P_ABE, shared between two honest parties and an eavesdropper. The most studied distillation scenari…
