### ON THE RELATIVITY OF THE MEASURE OF NONLOCALITY IN QUANTUM MECHANICS

#### Belinsky A.V., Shulman M.H.

A range of the relativistic clock paradox manifestations in Quantum Mechanics is considered. It is shown that all these phenomena can be explained using the united viewpoint. Really, for the moving photons the time currency is stopped and the travel length tends to zero. In other words, all the Universe “contracts” for them into the space-time point. So, the observed situation seems to be very different from this one in a laboratory reference frame. For example, any measurements on a pair of EPR-photons become exactly synchronized. Due the same reasons, some illusion of the causality violation may appear in the experiments wits the quantum eraser where one entangled photon detection is directed by another photon later manipulation. As we believe, the conventional opinion about quantum non-locality is not correct because of the non-locality measure turns out to be relative (not absolute) and depends on the reference frame choice, it may tend to zero. The more, such approach is correct for a massive particle (for example, electron), not for photon only. So, one could explain the “delayed choice”, Einstein-Podolsky-Rosen experiments, quantum teleportation, Tetrode’s paradox, “spooky action at a distance”, “direct action between particles”, instant quantum particle propagation via multiples trajectories, interaction-free measurement, passage from cause-effect link to correlations.
