Decoherence in the Transactional Interpretation

Abstract. This paper presents an analysis of decoherence resulting from the physically real non-unitarity, or ‘objective reduction,’ that occurs in the Transactional Interpretation (TI).  Two distinct aspects of the decoherence process are identified and disambiguated; specifically, (i) the resolution of the basic measurement interaction with respect to the observable under study, and (ii) the effect on the measured system of… Read more →

Topic for 2018 Int’l Workshop on Quantum Foundations

I would like to discuss the Relativistic Transactional Interpretation, specifically the explicit derivation of the Born Rule for radiative processes as presented in my recent paper with John Cramer ( It appears clear that TI and RTI provide a physical account of measurement as well as a physical derivation of the Born Rule. Previous objections to TI (such as that… Read more →

Submission: Quantifying Absorption in the Transactional Interpretation

R. E. Kastner, John G. Cramer  3 Feb. 2018 Abstract: The Transactional Interpretation offers a solution to the measurement problem by identifying specific physical conditions precipitating the non-unitary `measurement transition’ of von Neumann. Specifically, the transition occurs as a result of absorber response (a process lacking in the standard approach to the theory).  The purpose of this Letter is to make… Read more →

Addendum to Quantum Wave Function Collapse of a System Having Three anti Commuting Elements

Abstract : We indicate a new way in the solution of the problem of the quantum measurement . In past papers we used the well-known formalism of the density matrix using an algebraic approach in a two states quantum spin system S, considering the particular case of three anticommuting elements. We demonstrated that, during the wave collapse, we have a… Read more →

Particle or wave: there is no evidence of single photon delayed choice

Michael Devereux (Los Alamos National Laboratory) Wheeler supposed that the way in which a single photon is measured in the present could determine how it had behaved in the past. He named such retrocausation delayed choice. Over the last forty years many experimentalists have claimed to have observed single-photon delayed choice. Recently, however, researchers have proven that the quantum wavefunction of a single photon… Read more →
