“…The waves not only yield the probabilities for detecting photons, but they are supposed to have a certain physical reality, to the extent that an "empty" wave can cause photodetection. A number of experiments for testing the predictions of the guided-wave theory have been suggested, 7,8 but the one recently proposed by Croca et al 4 appears simpler and more conclusive than others. From their analysis, Croca et al conclude that the proposed experiment should result in observable interference effects in two-photon coincidence counting according to the de Broglie theory, but not according to quantum theory.…”

A two-photon interference experiment has been carried out, based on an idea recently proposed by Croca, Garuccio, Lepore, and Moreira. The experiment is designed to test a prediction of the de Broglie guided-wave theory, according to which the waves have a physical reality in addition to yielding photon detection probabilities. The results clearly contradict the de Broglie theory, but are consistent with conventional quantum mechanics.

“…In laser physics the same conclusion has been drawn (Mückenheim et al 1988), which seems to show the non-reality of the idea of empty waves with a velocity faster than light as they have been postulated by de Broglie and Einstein (see, e.g., Loschak 1984). A related proposal for an interferometer experiment was made by Croca et al (1988) to test this idea for neutrons. A second beam from an independent source should be fed into an interferometer loop and the residual interference pattern should be measured in a coincidence mode.…”

In this new edition we have retained the overall structure of the original book. It now consists of 12 chapters. We have shifted some material from later chapters to the first chapter. In particular, we have described gravitationally induced quantum interference (COW experiment) and early experiments on spin rotation, spinors, and spin-related phases in Chapter 1. These results have gotten broad attention in recent years and are now described in various standard physics textbooks. This change in format was done with a view of the close connection of these experiments with the atom interferometry field and with the modern ideas on entanglement now permeating all of the modern quantum mechanical literature.Neutron interferometry is a mature technique in experimental physics. The use of the perfect silicon crystal interferometer to accurately measure scattering lengths of many isotopes is given in Chapter 3. Very accurate measurements of the neutron scattering lengths of the proton, deuteron, and He-3 have been carried out in recent years. These results confine the parameters in various theoretical models of few-body nuclear physics.Chapter 4 is retitled "Coherence and Decoherence," so as to include many new topics connected to the current emphasis in certain areas of physics related to how coherent quantum systems decohere and evolve into systems described by classical Lagrangian and Hamiltonian mechanics. The quantum concepts of entanglement, contexuality, squeezing, Wigner functions, interactions of quantum systems with the environment, post selection experiments, measures of distinguishability, intensity-intensity correlations, and Bell's inequalities are the general topics of this expanded chapter. "Contexuality and Kochen-Specker Phenomena" are discussed in a new Chapter 7.Our original Chapter 8 dealing with forthcoming and more speculative experiments is now Chapter 10. Some of those experiments have advanced considerably over the intervening 12 years since the publication of the 1st edition. Experiments related to searches for non-Newtonian gravity at short distances have been pursued in various confined geometries, such as transmission through narrow slits. Related ideas, called "bouncing ball" experiments, have successfully observed quantized states of ultra-cold neutrons in the Earth's gravity. An experiment designed to observe the Anandan acceleration has not yet been attempted. The observation of relativistic proper time effects, as suggested in Chapter 8, occurs at the level of 10 -9 . Suggested observation of such effects in atom beam interferometry, related to a gravitational redshift, has generated interesting, but controversial papers. Perhaps there is a way to pursue such effects with neutron interferometry utilizing the Pendellösung interference fringes, as discussed in this chapter on "Gravitational, Inertial, and Motional Effects." A feasible time-dependent Fizeau experiment is described to study new motional effects and for the cooling of neutron beams.Various new techniques and experiments of...
