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...
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...
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...
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...
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...
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...
