Proposal of Signaling by Interference Control of Delayed-Choice   Experimental Setup
  We propose a new signaling system using the experimental setup of Wheeler's delayed-choice experiment previously carried out. In the delayed-choice experiment, the experimental setup shows a wave property or a particle property at the time when the experimental conditions of the wave-particle duality of photons are chosen. Choice signals can be used as transmitting signals and the wave-particle duality of photons is used as receiving signals. For example, if we choose the wave property of a photon as a transmitting signal, we detect the interference of the wave at the detector that can be used as a receiving signal. Therefore, the experimental setup of the delayed-choice experiment can transmit information through interference.
