Causal Loops and Collapse in the Transactional Interpretation of Quantum Mechanics

Abstract

Cramer's transactional interpretation of quantum mechanics is reviewed, and a number of issues related to advanced interactions and state vector collapse are analyzed. Where some have suggested that Cramer's predictions may not be correct or definite, I argue that they are, but I point out that the classical-quantum distinction problem in the Copenhagen interpretation has its parallel in the transactional interpretation.Comment: Minor changes, plus a significant correction in the caption of Fig. 2; forthcoming in Physics Essay
