A new EPR-Bohm experiment with reversible measurements.
[Preprint]
Abstract
It is usually thought that the EPR-Bohm experiment, unlike the Bell-type experiments, cannot be used to demonstrate the existence of nonlocal correlations that leads to potential incompatibility of quantum theory and special relativity. In this paper, I propose a variant of the original EPR-Bohm experiment, a new EPR-Bohm experiment with reversible measurements. It is argued that in this experiment, the correlation between the results of spacelike separated measurements depends on the temporal order of these measurements in a single-world unitary quantum theory. This violates special relativity, which requires that relativistically non-invariant relations such as the temporal order of spacelike separated events have no physical significance. Moreover, when assuming measurement results are Lorentz invariant, the temporal order dependent correlation further requires the existence of a preferred Lorentz frame. Finally, I analyze possible implications of these results for certain single-world unitary quantum theories.
