We are investigating, theoretically and with some practical experimentation, a project (one
photon, two photon) sending classical data down a quantum
channel (both patent protected). The central experimental tenants of this thesis have already been proven: that remote, non-local measurement does change distant wave-function collapse1,2 and that the speed of this collapse by coincidence counting3 was at least 10,000c. What remained was to show that the "No-communication theorem"4 could be violated5 and that a protocol could be devised to overcome the randomness of quantum measurement. The phenomenon of entanglement is quite robust too, persisting6 over many 10s of km. Thermal interaction ultimately disrupts entanglement as the particles take on random entanglement with the environment thermal bath7.

Yes, conceptually, it's this simple as the diagram
details are slightly involved though
simple, profound things can suffer much disbelief and obstruction. The 'M' is the
measurement, 'C' the constructive interference detector and 'D', the
N.B. This only works with a
single photon source NOT a coherent source. See note in image.
