We are investigating, theoretically and with some practical experimentation,
a project sending classical data down a quantum
channel.

Before naysayers come and say "No-communications theorem", we've tackled that
head-on (see proofs and "the misuse..." papers below). In short the NCT is wrong
because one needs to consider the joint-evolutions (**NB. the operators only
act on their respective systems**) of the systems before the
partial trace is taken, the trace is clearly space-like in operation and the
creation operators can be mapped outside the interferometers (hence the causal
delay in transiting the devices is irrelevant). All permissible within standard
quantum mechanics and backed up by countless experiments.

Some people are confused by the concepts so

Yes, conceptually, it's this simple as the diagram
below. Experimental
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
destructive

N.B. This only works with a
single photon source NOT a coherent source.
