讲座内容简介

      It has been debated whether quantum mechanics and special relativity are incompatible. Bell's theorem is an important cornerstone, but it does not give us a definite positive answer due to the existence of theoretical loopholes; there are unitary quantum theories which evade Bell's theorem and claim that they are compatible with special relativity. In this talk, I will address the important issue of whether unitary quantum theories are compatible with special relativity. I propose a new Gedanken experiment, a variant of EPR-Bohm experiment with a superobserver who can undo a measurement. In this experiment, there is a stronger correlation than the correlation investigated in Bell's theorem. Based on an analysis of the correlations in different Lorentz frames, I prove that unitary quantum theories are incompatible with special relativity, and in order to avoid the incompatibility, there must exist a preferred Lorentz frame in these theories. This closes the major theoretical loopholes of Bell's theorem, including relationalism, retrocausality, and superdeterminism.
