WebGisin (1991) showed that all the entangled pure states of two qubits violate a single Bell's inequality, namely the Clause-Horne-Shimony-Holt (CHSH) inequality (Clauser et al. , 1969), with two di erent measurement settings for each observer. This equivalence between entanglement and nonlocality for pure states is referred to as Gisin's theorem. WebOct 1, 2004 · We present a theorem that all generalized Greenberger-Horne-Zeilinger states of a three-qubit system violate a Bell inequality in terms of probabilities. All pure entangled states of a three-qubit system are shown to violate a Bell inequality for probabilities; thus, one has Gisin's theorem for thre …

WebApr 14, 2010 · Gisin's theorem assures that for any pure bipartite entangled state, there is violation of the inequality of Bell and of Clauser, Horne, Shimony, and Holt, revealing its contradiction with local realistic model. Whether a similar result holds for three-qubit pure entangled states remained unresolved. We show analytically that all three-qubit pure … WebOct 24, 2024 · The theorem is named after physicists and mathematicians Nicolas Gisin, Lane P. Hughston, Richard Jozsa and William Wootters, though much of it was established decades earlier by Erwin Schrödinger. The result was also found independently by Nicolas Hadjisavvas building upon work by Ed Jaynes, [4] [5] while a significant part of it was … WebFeb 12, 2008 · Abstract. We prove that there are tripartite quantum states (constructed from random unitaries) that can lead to arbitrarily large violations of Bell inequalities for dichotomic observables. As a consequence these states can withstand an arbitrary amount of white noise before they admit a description within a local hidden variable model. option yahoo
