WebOct 3, 2024 · The schematic setup, as shown in figure 1, is composed of two parts: the heralded entangled source and the CHSH test. The experiment setup for CHSH test consists of a polarization modulator (PM), a polarization beam splitter (PBS) and two detectors in Alice's side and similarly for Bob. The PM is used to choose different … WebMay 4, 2024 · A Bell test with CHSH score β ≈ 2. 7242 and a herald- ing probability p click ≈ 2 . 9 × 10 − 4 , or β ≈ 2 . 7424 with p click ≈ 2 . 6 × 10 − 5 .
WebJan 24, 2024 · Minimum value β θ t of the expectation value of the generalized CHSH operators B θ leading to a nontrivial self-testing bound (F ≥ 1 / 2) as a function of the parameter θ. For θ = π / 4, B π 4 corresponds to the CHSH operator and the trivial self-testing bound is β π 4 t ≈ 2.11 in agreement to the results of Refs. [12, 14]. WebNov 8, 2024 · The most simple way is to use the CHSH inequality to check if the two particles share some kind of non-classical correlations. Conversely, P&M protocols (e.g., …
Weblogically independent. A setting might be A = Bell test angle of 0, 22.5°, 45°, 67.5° or 90°. Counts in each setting category are measured, and an inequality involving set-combinations is stated as a test metric. There are many different examples of Bell inequalities (e.g., the ‘CHSH’ inequality for Clauser’s test). Webuses rest of the bits to perform CHSH test and calculates S. if S is approx 2rt2, no evedropping as occured by the CHSH inequality; we can add in an evedropper Eve who will be able to measure n/4 of Alice's qubits; we calculate the S value from CHSH and Alice and Bob use it to determine if there is an evedropper present; BB84 entangled
