Entanglement estimation from Bell inequality violation
Karol Bartkiewicz, Bohdan Horst, Karel Lemr +1
It is well known that the violation of Bell's inequality in the form given by Clauser, Horne, Shimony, and Holt (CHSH) in two-qubit systems requires entanglement, but not vice vers…
Two-qubit mixed states more entangled than pure states: Comparison of the relative entropy of entanglement for a given nonlocality
Bohdan Horst, Karol Bartkiewicz, Adam Miranowicz
Amplitude damping changes entangled pure states into usually less-entangled mixed states. We show, however, that even local amplitude damping of one or two qubits can result in mix…
Paradoxes of measures of quantum entanglement and Bell's inequality violation in two-qubit systems
Adam Miranowicz, Bohdan Horst, Andrzej Koper
We review some counterintuitive properties of standard measures describing quantum entanglement and violation of Bell's inequality (often referred to as "nonlocality") in two-qubit…
Comparison of the relative entropy of entanglement and negativity
Adam Miranowicz, Satoshi Ishizaka, Bohdan Horst +1
It is well known that for two qubits the upper bounds of the relative entropy of entanglement (REE) for a given concurrence as well as the negativity for a given concurrence are re…
