How could the detection of an interference pattern be affected by photons which do not enter the interferometer?
Belinskii A.V.
A three-photon interference experiment is proposed. In this experiment the contrast would be controlled by varying the conditions for the detection of photons which do not undergo an interference phase delay. In this experiment one can clearly demonstrate Feynman's uncertainty principle for explaining the Einstein-Podolsky-Rosen paradox involving energy-time observables.
