Entanglement Distribution in Pure-State Quantum Networks
S. Perseguers, J. Wehr, A. Acin +2
We investigate entanglement distribution in pure-state quantum networks. We consider the case when non-maximally entangled two-qubit pure states are shared by neighboring nodes of…

Entanglement of positive definite functions on compact groups
J. K. Korbicz, J. Wehr, M. Lewenstein
We define and study entanglement of continuous positive definite functions on products of compact groups. We formulate and prove an infinite-dimensional analog of Horodecki Theorem…

Hilbert's 17th problem and the quantumness of states
J. Korbicz, J. I. Cirac, J. Wehr +1
A state of a quantum systems can be regarded as {\it classical} ({\it quantum}) with respect to measurements of a set of canonical observables iff there exists (does not exist) a w…
