Event-by-Event Simulation

Quantum interference



Within the framework of quantum theory, it seems impossible to explain how the individual events that are registered by detectors conspire to form interference patterns, as observed in some of the most fundamental experiments in quantum physics such as
  • The double slit experiment with single electrons (A. Tonomura, The Quantum World Unveiled by Electron Waves, World Scientific, Singapore, 1998)
  • The single photon interference experiment (P. Grangier, G. Roger, and A. Aspect, "Experimental evidence for a photon anticorrelation effect on a beam splitter: A new light on single-photon interferences," Europhys. Lett. 1, 173-179 (1986), see also http://marcus.whitman.edu/~beckmk/QM/).
  • Single-photon interference experiments with a Fresnel biprism (Jacques V. et al., Eur. Phys. J. D 35, 561 (2005)).

The prevailing logic in quantum theory is to postulate that these phenomena cannot be explained. Instead of searching for possible explanations, it has become popular to prove all kinds of "no-go theorems" that purport to support this postulate. Although some of these theorems do not have the status of a mathematical theorem at all, it has become fashionable to believe that they are theorems. However, any respectable mathematical theorem is only valid under the conditions stated. Although quantum theory and probability theory are very useful to describe many of the phenomena that we observe in carefully designed experiments, the idea that Nature itself cares about mathematical conditions that we impose and mathematical theorems  that we, humans, invent would put us humans in a very privileged position.

The software on this website demonstrates that locally connected networks of processing units with a primitive learning capability (DLMs) are sufficient to simulate, event-by-event, the single-photon beam splitter and Mach-Zehnder interferometer experiments, double-slit experiments with photons, and many other quantum phenomena.

The simulation of the quantum processes is formulated in terms of events, messages and units that process these events and messages. The parts of the processing units and network map one-to-one on the physical parts of the experimental setup and no reference is made to any concept of quantum theory. Yet, these systems generate events such that their distribution is indistinguishable from the one given by quantum theory.
