The Degree of Quantum Contextuality in Terms of Concurrence for the KCBS Scenario

نویسندگان

چکیده

Quantum contextuality is the key concept which explains fact that result of a measurement not independent context in it found. It observed to be an intrinsic feature, i.e., neither entanglement nor spatial separation required. In this work, we revisit previous studies state property called self-entanglement. Using fact, explicitly show correlation between quantum and concurrence KCBS scenario, simplest approach observing contextuality. We also derive equation for maximal violation scenario given find linear relation them. relation, how violations CHSH inequalities are related arbitrary entanglement. Moreover, discuss special cases entanglement, non-entanglement have found lower local bound.
