Performance of an Ideal Quantum Receiver of a Coherent Signal of Random Phase
Carl W. Helstrom · IEEE Transactions on Aerospace and Electronic Systems · 1969
An ideal quantum receiver is to detect a coherent narrow-band optical signal in the presence of thermal background radiation. Curves are given both of the average probability of error in a binary communication system transmitting O's (blanks) and 1's (pulses) with equal probabilities, and of the probability of detection for various fixed values of the false-alarm probability.
