Threshold effect for probabilistic entanglement swapping

Entanglement breaking channels and entanglement sudden death
(American Physical Society, 2016-07)
The occurrence of entanglement sudden death in the evolution of a bipartite system depends on both the initial state and the channel responsible for the evolution. An extreme case is that of entanglement breaking channels, ...
Quantum entanglement of helium-like systems with varying-Z: Compact state-of-the-art CI wave functions
(Iop Publishing, 2015-07-17)
In this work we have performed state-of-the-art configuration-interaction (CI) calculations to determine the linear and von Neumann entanglement entropies for the helium-like systems with varying nuclear charge Z in the ...
Why entanglement of formation is not generally monogamous
(2013-03-13)
Unlike correlation of classical systems, entanglement of quantum systems cannot be distributed at will: if one system A is maximally entangled with another system B, it cannot be entangled at all with a third system C. ...

Entanglement universality of two-qubit X-states
(Elsevier B.V., 2014-12-01)
We demonstrate that for every two-qubit state there is a X-counterpart, i.e., a corresponding two-qubit X-state of same spectrum and entanglement, as measured by concurrence, negativity or relative entropy of entanglement. ...
