The FLASH communicator consists of an apparatus which can distinguish between plane unpolarized (PUP) and circularly unpolarized (CUP) light plus a simple EPR arrangement. FLASH exploits the peculiar properties of “measurements of the Third Kind.” One purpose of this article is to focus attention on the operation of idealized laser gain tubes at the one-photon limit.
