I continue to get claims that the Transactional Formulation of quantum mechanics (now called RTI) isn't really a "theory" because it doesn't lead to "empirically testable differences" from conventional quantum theory. So I thought I'd share an email reply to someone who recently made this claim: But RTI does lead to empirically testable differences with … Continue reading RTI is a different theory from conventional quantum mechanics; it passes empirical tests routinely failed by the conventional theory →

There has recently been renewed discussion of an experiment involving nested interferometers (presented by Danan et al, 2013). This experiment has been used by those authors (and others) to argue for the correctnesss of a formulation of quantum theory known as the "Two State Vector Formalism: (TSVF). In this paper, I take a close look … Continue reading Where Photons Have Been: nowhere without all of their wavefunctions →
