The CHSH inequality is a statement about a linear combination of expectation values of different products of observables. It is not a statement about the outcome of a single measurement. Thus, violation of the CHSH inequality can only be inferred in a statistical sense after performing many repetitions of the experiment.

WebThe CHSH experiments slow the generation of photon pairs from one BBO so that at least 25ns separates the pairs in time. That seems to make the state of the polarization known, not indeterminate. When one of the detectors is set to match vertical polarization, one of its counters registers vertical polarization and the other registers ... In practice most actual experiments have used light, assumed to be emitted in the form of particle-like photons (produced by atomic cascade or spontaneous parametric down conversion), rather than the atoms that Bell originally had in mind. The property of interest is, in the best known experiments, the polarisation direction, though other properties can be used. Such experiments fall into two … highland burial parkWebA Typical CHSH Experiment. In practice most actual experiments have used light rather than the electrons that Bell originally had in mind. The property of interest is, in the best known experiments (Aspect, 1981-2), the polarisation direction, though other properties can be used.

WebWe briefly recall the setting for the Bell–CHSH experiment. Section 2 provides a more detailed account. A famous application of nonlocality is to construct an 1-2 oblivious transfer protocol between two distant agents (A)lice and (B)ob. Alice and Bob each hold a box. Alice’s box might, for example, contain one half of a singlet state of spin– 1 2 particles, … Webin our experiment by recording the number of coincident signal/idler photon pairs detected at the APDs when the polarizers are aligned to the different combinations of angles. Using this, we must choose angles for which it is possible to violate Bell’s inequality. The CHSH inequality uses a correlation of the probabilities defined as follows:

WebRalph CNOT Gate. We start by describing the circuit as defined by the paper above- it is a circuit on six modes (labelled from 0 to 5 from top to bottom) consisting of five beam splitters. Modes 1 and 2 contain the control system while modes 3 and 4 encode the target system. Modes 0 and 5 are unoccupied ancillary modes.
