> entangled photons of light have been used to transmit information in such a way that any interception is detectable Wrong. Information is not transmitted via the entangled photons. They're used to build up random data, which is guaranteed to correspond between the two endpoints and thus can be used as an encryption key (for a one-time pad, etc). Entanglement can certainly not be used to transmit information.
