Abstract. This paper presents an analysis of decoherence resulting from the physically real nonunitarity, or ‘objective reduction,’ that occurs in the Transactional Interpretation (TI). Two distinct aspects of t […]

Reply to Aurelien: No, RTI has emphatically nothing to do with Bohr or the Copenhagen interpretation, which I criticize and reject here:https://arxiv.org/abs/1601.07545
If you read my publications, you will find that I assign objective physical reality to quantum states and the advanced states. You seem to be implicitly assuming that for something…[Read more]

To Shan: That is correct. The collapse occurs with respect to projection operators (outer products), not with respect to kets. That is, from absorber response to each component we get two weighted projection operators:Psi1><Psi1 and Psi2><Psi2, where each is weighted by the Born Rule based on the prepared state. So if the prepared state was…[Read more]

Dear Aurelien, RTI does not require any preferred foliation; it does not require any future boundary condition. It is not a hidden variable approach nor does it rely on a notion that measurement outcomes are ‘already there’ in the future–i.e. it is not a block world ontology. I understand that the original TI may have seemed to imply that, but…[Read more]

Thanks Shan. In RTI the quantum state Psi> is fully ontic. But the advanced state <Psi is also fully ontic, so RTI is a different animal from the usual ‘quantum interpretation.’ This is why it is not subject to the dilemma you pose. It has real ontic collapse, but the collapse is not with respect to just a forwardpropagating quantum state. In…[Read more]

Thanks Aurelien, I am indeed aware of the Sutherland model and you are correct that it is covariant, except perhaps for the final boundary condition which has to be defined in a particular frame (but it’s a matter of debate as to whether that ‘really’ fixes a preferred frame). Other than the final B.C., the model preserves full Lorentz covariance.…[Read more]

Ruth Kastner replied to the topic Quantum theory is incompatible with relativity: A proof beyond Bell's theorem in the forum 2019 International Workshop: Beyond Bell's theorem 3 years, 7 months ago
I’m afraid this is not the correct conclusion. While RTI is certainly not the usual ad hoc collapse theory, it certainly is a nonunitary objective reduction theory (see below). So it cannot be subject to your argument concerning unitaryonly theories. There is real dynamical reduction in TI–it just does not take the form that you’ve assumed…[Read more]

But the existence of the observed correlation does not compel the idea that there is some sort of collapse signal that ‘travels faster than light.’ You might be supposing that such a ‘collapse signal’ is needed to enforce the correlation, but that is not the case in TI, where the correlation is enforced through the combination of the quantum state…[Read more]
