Abstract: An optical information transmission system capable of achieving an information transmission at a signal to noise ratio greater than that which is achievable using classical optical transmission techniques if disclosed. The higher signal to noise ratio is achieved by employing a non-classical, i.e. quantum mechanical, optical transmission technique. To achieve non-classical transmission effects, a non-degenerate optical parametric amplifier is employed to generate a pair of signal beams having highly correlated quantum noise. Information is then encoded within each of the signal beams at a signal level far below the level of the quantum noise. Accordingly, information encoded on the beams is substantially obscured by the quantum noise, thereby effectively preventing unwanted eavesdropping of the transmitted information. After transmission, the pair of separate signal beams are detected and combined by a receiver.
