Quantum entanglement
All our former experience with application of quantum theory seems to say: {\it what is predicted by quantum formalism must occur in laboratory}. But the essence of quantum form...

We prove continuity of quantum conditional information $S(\\rho^{12}| \\rho^2)$\nwith respect to the uniform convergence of states and obtain a bound which is\nindependent of th...
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 a method of direct estimation of important properties of a shared bipartite quantum state, within the ``distant laboratories'' paradigm, using only local operations a...
