WebApr 7, 2024 · For the purposes of deciding whether or not a channel is CHSH-breaking, the unitaries U i and U o above can be absorbed by the state and measurements in the CHSH Inequality respectively. Hence, the CHSH-breaking conditions only need to be derived for diagonal . A special class of quantum channels called unital channels have the property … WebIn the past decades, many experiments have been designed to test the Bell’s inequality or Clauser-Horne-Shimony-Holt inequality [1,6{8,10]. Today, the two inequalities are of great impor-tance to quantum information and computation [3,4,11,12]. Very recently, we [5] have shown the math contradictions in Bell’s argument for his inequality.

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. Experimental verification of the inequality being violated is seen as confirmation that nature … 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 separate subexperiments. The terms E(a, b) … See more Many Bell tests conducted subsequent to Alain Aspect's second experiment in 1982 have used the CHSH inequality, estimating the terms using (3) and assuming fair … See more In experimental practice, the two particles are not an ideal EPR pair.

In addition to Bell's original inequality, [3] the form given by John Clauser, Michael Horne, Abner Shimony and R. A.
