Rescaling multipartite entanglement measures for mixed states
Oliver Viehmann, Christopher Eltschka, Jens Siewert
A relevant problem regarding entanglement measures is the following: Given an arbitrary mixed state, how does a measure for multipartite entanglement change if general local operat…
Multipartite-entanglement monotones and polynomial invariants
Christopher Eltschka, Thierry Bastin, Andreas Osterloh +1
We show that a positive homogeneous function that is invariant under determinant-1 stochastic local operations and classical communication (SLOCC) transformations defines an N-qubi…
Polynomial invariants for discrimination and classification of four-qubit entanglement
Oliver Viehmann, Christopher Eltschka, Jens Siewert
It is well known that the number of entanglement classes in SLOCC (stochastic local operations and classical communication) classifications increases with the number of qubits and…
