Chsh test
WebIn the case of polarisation entangled photon pairs (as emitted from the quED ), the so-called “CHSH” inequality is often chosen. Classical (“local realistic”) theories predict that a certain value “S” has an upper bound of 2 … WebOct 19, 2012 · A mathematical tour de force has recently provided a robustness bound for the Mayers–Yao test . To our knowledge, no robust bound is available for the CHSH test, a situation that plagues the applicability of the corresponding device-independent assessment of entanglement of a source and a measurement .

WebAs with the CHSH test, there are four subexperiments in which each polariser takes one of two possible settings, but in addition there are other subexperiments in which one or …
They derived the CHSH inequality, which, as with John Stewart Bell 's original inequality, [2] is a constraint on the statistical occurrence of "coincidences" in a Bell test which is necessarily true if there exist underlying local hidden variables, an assumption that is sometimes termed local realism. See more In physics, the CHSH inequality can be used in the proof of Bell's theorem, which states that certain consequences of entanglement in quantum mechanics cannot be reproduced by local hidden-variable theories. … See more The usual form of the CHSH inequality is where a and a′ are detector settings on side A, b and b′ on side B, the four combinations being tested in … See more The original 1969 derivation will not be given here since it is not easy to follow and involves the assumption that the outcomes are all +1 or −1, never zero.

Recently we developed a framework for building large self-tests by repeating a smaller self-test many times in parallel. However, the framework did not apply to the CHSH test, which tests a maximally entangled pair of qubits.
