Three-party entanglement from positronium
A. Acin, J. I. Latorre, P. Pascual
The decay of ortho-positronium into three photons produces a physical realization of a pure state with three-party entanglement. Its quantum correlations are analyzed using recent…

Generalized Schmidt decomposition and classification of three-quantum-bit states
A. Acin, A. Andrianov, L. Costa +3
We prove for any pure three-quantum-bit state the existence of local bases which allow to build a set of five orthogonal product states in terms of which the state can be written i…
