Abstract
An experiment has been carried out to test a prediction of the deBroglie guided wave theory for photons. According to this theory, there exist electromagnetic waves as well as photons, with the former acting as guide for the latter. The wave not only determines the probability for the detection of a photon, but it also has an independent physical reality which can result in photodetection, As a result the guided wave theory predicts an interference effect when two photons pass through an interferometer with a particular geometry and one measures the rate of simultaneous detections by two photodetectors in coincidence as a function of optical path difference, By contrast, quantum mechanics predicts no interference under the same conditions. The experimental results clearly violate the prediction of the guided wave theory, but are in agreement with quantum mechanics.
