Timelike Nonseparability and Retrocausation
Olivier Costa de Beauregard
Abstract
Renewed interest in the quantum zigzagging causality model is highlighted by an ingenious proposal by Suarez (quant-ph/9801061) to test the timelike aspect of nonseparability. Taking advantage of a work by Froehner I argue that the Dirac representation of a state, has the Bayesian-like connotation of best estimate given the Hilbert frame chosen. As a measurement perturbs uncontrollably a system it is (Hoekzema's wording) a retroparation. My bet is that Suarez' sources and sinks of paired particles operating inside the coherence length of the laser beam will evidence retrocausation.
