A Delayed Choice Gedanken Experiment

Authors: M. W. Roberts

A delayed choice experiment is proposed. A signal and idler pair of photons are sent to optical circulators. The fate experienced by the idler photon is described by two different cases. In case I, the idler photon has zero probability to reflect from the entrance beam splitter and therefore always enters its optical circulator. In case II, the idler photon has a non-zero probability to reflect from the entrance beam splitter without entering its optical circulator. Which case the idler photon actually experiences is selected by the method that is used to detect the signal photon of the pair. This is true, even if the detection of the signal photon occurs long after the detection of the idler photon.
