Bell's instantaneous action at a distance

摘要

In a paper published in 1964, John Bell claimed to prove that measurements made on pairs of particles in an entangled quantum state could influence each other instantaneously, regardless of the distance separating them. This claim and its proof are known as "Bell's theorem." It was based on apparent conflicts between correlations predicted by quantum mechanics and those based on his theoretical model of local measurements. An earlier critique of Bell's theorem by this author has been expanded and clarified to include Bell's original argument and the more recent concept of "experiments not performed" as examples. It is shown here that the apparent conflicts in both cases are caused by improper mathematical treatment of the hidden variables when multiple measurements are considered. Consequently, Bell's postulated instantaneous interaction and its possible violation of relativity are not justified. An experiment is suggested that could test the existence of the instantaneous interaction between the measurements postulated by Bell.
