Turning an Impractical Experiment for a Non-Trivial Non-Local Quantum Communications Device into a Practical One

In 2011, an impractical experiment to test a method for a non trivial non local quantum communication device was proposed that involved an idler photon initially entangled with a signal photon where the idler photon initially supplied which way info to the signal photon. A delayed choice was possible to lose or destroy the idler photon in many other photons released from a photon reservoir and eliminate the entanglement before the paired signal photon was detected. The result of the delayed choice is a different distribution of the idler photons over many runs than when the idler photon is not lost or destroyed over many runs. Now this experiment appears practical to do with the use of an ultrafast light switch to create many photons that flood the area through which the idler photon passes before the signal photon is lost or destroyed. This new experiment is described.
