A Laser Communications Network with, almost, zero latency.

Fig. 1. Experimental setup for holography with undetected light. Laser light (purple) pumps the nonlinear crystal (ppKTP) bidirectionally (beam paths a and d). It generates signal (red) and idler (green) beams either in the forward direction (beam paths b and c) or backward direction (beam paths e and f). Dichroic mirrors DM1 to DM3 separate the different beam paths. Idler light will illuminate the object (beam path c), while its hologram will be detected on the scientific complementary metal-oxide semiconductor (sCMOS) camera with the signal light (beam path e). The mirrors M1 to M3 are the interferometer end mirrors. M2 is mounted on a piezo stage to precisely move the mirror in one direction. Lenses L1 to L5 form the imaging system with the focal distances of 150 mm (L1, L2, and L3), 100 mm (L4), and 125 mm (L5).

Using entangled photons, it is possible to develop a communications system with instantaneous point to point transmission. The only delays in a communication network will be at the transceivers at the network nodes. Most people, and most physicists believe that it is not possible to communicate information faster than the speed of light. However, in my world, experiment trumps theory. I don’t know how to explain it with respect to relativity, but experiment is king. Although this experiment does not definitively prove that the image is communicated instantaneously, it is consistent with the fact that entangled particles do communicate instantaneously. Everyone just assumed that relativity would not allow communication at this speed.

In the research paper, “Quantum Holography with undetected light”, they showed that it was possible to sense an interaction of an entangled photon with a target to be sensed by its entangled partner in a camera. In this implementation, the camera receives a complete image. It uses holography, or interference to detect a remote object by detecting the amplitude and phase of the entangled photons. Right now, the resolution of this image is very low, but this can be improved with more development. In this experiment, the interaction of the first set of entangled photons is detected by the camera instantaneously. Here…
