Nonlocality of a single particle.
There has been a great deal of debate surrounding the issue of whether it is possible for a single photon to exhibit nonlocality. A number of schemes have been proposed that claim to demonstrate this effect, but each has been met with significant opposition. The objections hinge largely on the fact that these schemes use unobservable initial states and so, it is claimed, they do not represent e...
متن کاملNonlocality of a Single Photon Revisited Again.
Recently, Hardy[1] argued that the nonlocality of the quantum theory can be demonstrated for a single particle. The nonlocality means the impossibility of constructing a local hidden variable theory reproducing the predictions of quantum theory. However, Bohm[2] had constructed such a theory, i.e., hidden variable theory local at the one particle level, and therefore, Hardy's claim cannot be tr...
متن کاملComment on "Nonlocality of a single photon"
Tan, Walls, and Collett propose an experiment involving a single photon incident on a half-silvered mirror which may be detected in either of two homodyne detectors, each including a local oscillator [1]. They conclude that the quantum prediction for the intensity correlation coefficient involving four photodetectors "may not be explained classically using a particle, wave, or hiddenvariables t...
متن کاملThree-particle GHZ correlations without nonlocality
The formalism employing local complex amplitudes that resolved the Einstein-Podolsky-Rosen puzzle (C. S. Unnikrishnan, quant-ph/0001112) is applied to the three-particle GHZ correlations. We show that the GHZ quantum correlations can be reproduced without nonlocality. We have recently shown that quantum correlations can be reproduced starting from local probability amplitudes, by calculating th...
متن کاملHow a single particle simultaneously modifies the physical reality of two distant others: a quantum nonlocality and weak value study
The concept of wave-particle duality, which is a key element of quantum theory, has been remarkably found to manifest itself in several experimental realizations as in the famous double-slit experiment. In this specific case, a single particle seems to travel through two separated slits simultaneously. Nevertheless, it is never possible to measure it in both slits, which naturally appears as a ...
