From Bell’s Theorem to Secure Quantum Key Distribution
The first step in any quantum key distribution (QKD) protocol consists of sequences of measurements that produce correlated classical data. We show that these correlation data m...

Here we present experimental realizations of two new entanglement detection methods: a three-measurement Bell inequality inequivalent to the Clauser-Horne-Shimony-Holt inequalit...
Distillability, Bell Inequalities, and Multiparticle Bound Entanglement
We study the relation between violation of Bell inequalities and\ndistillability properties of quantum states. Recently, D\\"ur has shown that\nthere are some multiparticle boun...
Quantum Correlations and Secret Bits
It is shown that (i) all entangled states can be mapped by single-copy measurements into probability distributions containing secret correlations, and (ii) if a probability dist...
Multipartite Bound Information Exists and Can Be Activated
We prove the conjectured existence of bound information, a classical analog of bound entanglement, in the multipartite scenario. We give examples of tripartite probability distr...
Coincidence Bell Inequality for Three Three-Dimensional Systems
We construct a Bell inequality for coincidence probabilities on a three three-dimensional (qutrit) system. We show that this inequality is violated when each observer measures t...
Optimal estimation of two-qubit pure-state entanglement
We present optimal measuring strategies for the estimation of the\nentanglement of unknown two-qubit pure states and of the degree of mixing of\nunknown single-qubit mixed state...
