Reply to Hiley and Callaghan on the Reality/Surrealism of the Bohm Trajectories Conference Paper uri icon


  • In the paper by Englert, Scully, Süssmann and Walther [ESSW], entitled "Surrealistic Bohm Trajectories", it is shown that the physically appealing aspects of Bohm Trajectories are negated when which-path detectors are involved. As Hiley and Callaghan[HC] note, "[this has] formed a rich area for investigating the puzzling behaviour of particles undergoing quantum interference." At the present conference (Quantum Theory: reconsideration of foundations - 3, Växjö Universitet) and in a related preprint HC state that "Here trajectories actually cross because there is no coherence between the separate components of the mixed state". We respond to the criticism of HC via a simple example showing that the analysis of ESSW stands; and show where we disagree with HC. © 2006 American Institute of Physics.
