Abstract

We study the general coherent-state hypothesis testing problem and the capacity of the pure-loss optical channel with a coherent processing receiver (a receiver that uses coherent feedback control and direct detection). We describe the binary hypothesis minimum probability of error receiver as optimizing the communication efficiency at each instant, based on recursively updated knowledge of the receiver. Using this viewpoint, we give a natural generalization of the designs to general M-ary hypothesis testing problems. We analyze the information capacity with coherent receivers, and compare the result with that with direct detection receivers and with arbitrary quantum receivers (the Holevo limit), using the appropriate scalings in the low photon number regime.
