Concurrence of mixed multi-partite quantum states
Florian Mintert, Marek Kus, Andreas Buchleitner
We propose generalizations of concurrence for multi-partite quantum systems that can distinguish qualitatively distinct quantum correlations. All introduced quantities can be evalu…
Concurrence of mixed bipartite quantum states in arbitrary dimensions
Florian Mintert, Marek Kus, Andreas Buchleitner
We derive a lower bound for the concurrence of mixed bipartite quantum states, valid in arbitrary dimensions. As a corollary, a weaker, purely algebraic estimate is found, which de…
Global entangling properties of the coupled kicked tops
Rafal Demkowicz-Dobrzanski, Marek Kus
We study global entangling properties of the system of coupled kicked tops testing various hypotheses and predictions concerning entanglement in quantum chaotic systems. In order t…
