Maximal Bell’s Inequality Violation for Non Maximal Entanglement
نویسنده
چکیده
Bell’s inequality violation (BIQV) for correlations of polarization is studied for a product state of two two-mode squeezed vacuum (TMSV) states. The violation allowed is shown to attain its maximal limit for all values of the squeezing parameter, ζ. We show via an explicit example that a state whose entanglement is not maximal allow maximal BIQV. The Wigner function of the state is non negative and the average value of either polarization is nil. PACS : 2.0; 03.65.Bz

Degree of entanglement for two qubits
We demonstrate that any pure bipartite state of two qubits may be decomposed into a superposition of a maximally entangled state and an orthogonal factorizable one. Although there are many such decompositions, the weights of the two superposed states are, remarkably, unique. We propose a measure of entanglement based on this decomposition. We also demonstrate that this measure is connected to t...
متن کاملOptimization of Bell’s Inequality Violation For Continuous Variable Systems
Two mode squeezed vacuum states allow Bell’s inequality violation (BIQV) for all non-vanishing squeezing parameter (ζ). Maximal violation occurs at ζ → ∞ when the parity of either component averages to zero. For a given entangled two spin system BIQV is optimized via orientations of the operators entering the Bell operator (c.f. S. L. Braunstein, A. Mann and M. Revzen: Phys. Rev. Lett. 68, 3259...
متن کاملQuantum Entanglement under Lorentz Boost
In order to understand the characteristics of quantum entanglement of massive particles under Lorentz boost, we first introduce a relevant relativistic spin observable, and evaluate its expectation values for the Bell states under Lorentz boost. Then we show that maximal violation of the Bell’s inequality can be achieved by properly adjusting the directions of the spin measurement even in a rel...
متن کاملEntanglement estimation from Bell inequality violation
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 versa, i.e., there are entangled states which do not violate the CHSH inequality. Here we compare some standard entanglement measures with violations of the CHSH inequality (as given by the Horodecki measure) for two-qubi...
متن کاملQuantum Nonlocality and Inseparability
wK = 1. A necessary condition for separability is derived and is shown to be more sensitive than Bell’s inequality for detecting quantum inseparability. Moreover, collective tests of Bell’s inequality (namely, tests that involve several composite systems simultaneously) may sometimes lead to a violation of Bell’s inequality, even if the latter is satisfied when each composite system is tested s...
