Three-tangle for mixtures of generalized GHZ and generalized W states
Christopher Eltschka, Andreas Osterloh, Jens Siewert +1
We give a complete solution for the three-tangle of mixed three-qubit states composed of a generalized GHZ state, a|000>+b|111>, and a generalized W state, c|001>+d|010>+f|100>. Us…

Broken Symmetries in the Entanglement of Formation
F. Benatti, H. Narnhofer, A. Uhlmann
We compare some recent computations of the entanglement of formation in quantum information theory and of the entropy of a subalgebra in quantum ergodic theory. Both notions requir…
