An Entropy Inequality

Meik Hellmund, Armin Uhlmann

Let $S (ρ) = - T r (ρ lo g ρ)$ be the von Neumann entropy of an $N$ -dimensional quantum state $ρ$ and $e_{2} (ρ)$ the second elementary symmetric polynomial of the eigenvalues of $ρ$ . We pr…

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…
