Direct quantum communication with almost invisible photons Academic Article uri icon


  • We propose a protocol for direct quantum communication between two parties (Alice and Bob) which is achieved by controlling the phase of the signal photon. Without imperfection and noise, Alice's two detectors always click with unit probability according to Bob's different decisions. The probability of detecting a photon in the transmission channel can be controlled and can be made arbitrarily small by increasing the resources. 2014 American Physical Society.
