Annihilating and creating nonlocality without entanglement by postmeasurement information

چکیده
Nonlocality without entanglement (NLWE) is a nonlocal quantum phenomenon that arises in separable state discrimination. We show the availability of postmeasurement information about prepared subensemble can affect occurrence NLWE discriminating non-orthogonal nonentangled states. provide two-qubit ensemble consisting four nonorthogonal pure states and annihilate NLWE. also another create Our result useful method to share or hide using

متن کاملNonlocality without nonlocality∗
Bell’s theorem is purported to demonstrate the impossibility of a nonlocal “hidden variable” theory underpinning quantum mechanics. It relies on the well-known assumption of ‘locality’, and also on a little-examined assumption called ‘statistical independence’ (SI). Violations of this assumption have variously been thought to suggest “backward causation”, a “conspiracy” on the part of nature, o...

Département de l’Informatique, UQO, Case postale 1250 ,succursale Hull, Gatineau. Quebec, Canada J8X 3X 7 Abstract. Quantum nonlocality is presented often as the most remarkable and inexplicable phenomenon known to modern science which was confirmed in the experiments proving the violation of Bell Inequalities (BI). It has been known already for a long time that the probabilistic models used to...
متن کاملMore nonlocality with less entanglement
Recent numerical investigations [K. Pál and T. Vértesi, Phys. Rev. A 82, 022116 (2010)] suggest that the I3322 inequality, arguably the simplest extremal Bell inequality after the CHSH inequality, has a very rich structure in terms of the entangled states and measurements that maximally violate it. Here we show that for this inequality the maximally entangled state of any dimension achieves the...
متن کاملA Closer Connection Between Entanglement and Nonlocality
Entanglement, first introduced by Einstein, Podolsky, and Rosen [1], and Schrödinger [2] in 1935, can arise when two quantum systems are produced from a common source, for instance, when two particles are produced with opposite spin in a decay process. Mathematically, this means that the state of the quantum system cannot be written as a mixture of product states of its constituent subsystems. ...
