WebCHSH Inequality In addition to Bell's original inequality, the form given by John Clauser, Michael Horne, Abner Shimony and R. A. Holt, (the CHSH form) is especially important, as it gives classical limits to the expected correlation for the above experiment conducted by Alice and Bob: where C denotes correlation.

WebMar 17, 2024 · One of the most important Bell inequalities is the Clauser–Horne–Shimony–Holt (CHSH) inequality [ 10] for two-qubit systems. In [ 11] Horodeckis have presented the necessary and sufficient condition of violating the CHSH inequality by an arbitrary mixed two-qubit state. WebApr 6, 2024 · The fact that we violated the CHSH inequality in our real device is of significance. Just a decade ago such an experiment would have been of great impact. …
WebOct 21, 2015 · Combined with measured read-out fidelities, the generated entangled state is thus expected to violate the CHSH–Bell inequality with S = 2.30 ± 0.07.

WebA Bell test, also known as Bell inequality test or Bell experiment, is a real-world physics experiment designed to test the theory of quantum mechanics in relation to Albert Einstein's concept of local realism.
WebAug 24, 2015 · For more than 80 years, the counterintuitive predictions of quantum theory have stimulated debate about the nature of reality. In his seminal work, John Bell proved that no theory of nature that obeys locality and realism can reproduce all the predictions of quantum theory. Bell showed that in any local realist theory the correlations between … WebCHSH Inequality In addition to Bell's original inequality, the form given by John Clauser, Michael Horne, Abner Shimony and R.
