The evolution of the expectation values of one- and two-point scalar field operators and of positive localization operators generated by an instantaneous point-source is non-local. Non-locality is attributed either to zero-point vacuum fluctuations, or to non-local operations or to the microcausality principle being not satisfied.

Abstract
The evolution of the expectation values of one- and two-point scalar field operators and of positive localization operators generated by an instantaneous point-source is non-local. Non-locality is attributed either to zero-point vacuum fluctuations, or to non-local operations or to the microcausality principle being not satisfied.
