Hardy is (almost) everywhere: Nonlocality without inequalities for almost all entangled multipartite states
We show that all n-qubit entangled states, with the exception of tensor products of single-qubit and bipartite maximally-entangled states, admit Hardy-type proofs of non-locality without inequalities or probabilities. More precisely, we show that for all such states, there are local, one-qubit observables such that the resulting probability tables are logically contextual in the sense of Abrams...
متن کاملNonlocality for two particles without inequalities for almost all entangled states.
Bell's 1964 demonstration [1] that realistic interpretations of quantum theory must be nonlocal required the use of inequalities now universally known as Bell inequalities. Greenberger, Horne, and Zeilinger (GHZ) [2) caused much interest when they gave a proof of nonlocality but without using inequalities. Their proof, however, requires a minimum of three particles. A proof of nonlocality witho...
متن کاملIi. Nonlocality without Inequalities for Hardy States
Hardy’s proof of “nonlocality without inequalities” [1] provides the simplest demonstration of Bell’s theorem [2] that there is no local realistic theory reproducing all predictions of quantum mechanics. Curiously, while the maximum violation of Bell inequalities occurs for maximally entangled states [3], Hardy’s proof does not go through for maximally entangled states. Recently, Wu, Xie, Huang...
متن کاملNonlocality without inequality for almost all two-qubit entangled state based on Cabello’s nonlocality argument
Here we deal with a nonlocality argument proposed by Cabello which is more general than Hardy’s nonlocality argument but still maximally entangled states do not respond. However, for most of the other entangled states maximum probability of success of this argument is more than that of the Hardy’s argument.
متن کاملLadder proof of nonlocality without inequalities for maximally entangled states
The ladder proof of nonlocality without inequalities for two spin-12 particles proposed by Hardy et al. [1, 2] works only for nonmaximally entangled states and goes through for 50% of pairs at the most. A similar ladder proof for two spin-1 particles in a maximally entangled state is presented. In its simplest form, the proof goes through for 17% of pairs. An extended version works for 100% of ...
