Note, in this case signal strength S to detect the atomic qubit receiver B in state |g> or |e> from the trapped ion nano-mechanical oscillator sender A - of course the trick will be to get a system in which A and B can be spatially separated.

SB(g or e) ~ e^-<n>A[1 - cos(phiA)]

take the difference


<n>A = |alpha|^2


The message is in the function phi(t)
