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. WebApr 6, 2024 · The above inequality is called CHSH after Clauser, Horne, Shimony, and Holt, and it is the most popular way of presenting the original inequality from Bell. The …
WebThe CHSH inequality is S = E ( a, b) − E ( a, d) + E ( c, b) + E ( c, d) ≤ 2. It, like Bell’s inequality, is valid for all values from – 1 to + 1. To avoid having 2 a ’s, separate letters … WebMar 6, 2024 · Tsirelson's inequality, discovered by Boris Tsirelson in 1980, [16] states that for any quantum strategy S for the CHSH game, the bias β CHSH ∗ ( S) ≤ 1 2. Equivalently, it states that success probability ω CHSH ∗ ( S) ≤ cos 2 ( π 8) = 1 2 + 1 2 2 for any quantum strategy S for the CHSH game. In particular, this implies the ...
WebThe most complete study of Bell inequalities is for the case (n, m, v) = (n, 2, 2). n-particle generalizations of the CHSH inequality were first proposed by Mermin (Mermin, 1990), and Belinskii and Klyshko (Belinskii & Klyshko, 1993), and have been extended by Werner and Wolf (Werner & Wolf, 2000), and Zukowski and Brukner (Zuckowski & Brukner ...
