Quantum interference and entanglement of photons that do not overlap in time. Conference Paper uri icon


  • We discuss the possibility of quantum interferences and entanglement of photons that exist at different intervals of time, i.e., one photon being recorded before the other has been created. The corresponding two-photon correlation function is shown to violate Bell's inequalities.
