Query: A telecommunications system based on axion dark matter coherent
  transmission   In this manuscript we anticipate axion detection in order to theorize on a
novel telecommunications system based on the coherent axion-two-photon vertex
Primakoff effect conversion and reversion of microwave photons transmitting a
modulated signal. We suggest a possible set-up for an experiment or industrial
application using state-of-the-art technology and we estimate the output power
and photon rate expected to be received as a function of the axion-photon
coupling constant $g_{a\gamma\gamma}$. We find that, although challenging,this
system has no physical restriction to render it unfeasible. Finally, we
summarize the advantages and disadvantages of a hypothetical axion-based
telecommunications system compared to traditional telecommunication systems. We
then extend the discussion, noting the more important conclusions.
