Theoretical and Mathematical Physics Aims and scope Submit manuscript

Abstract

A quantum channel is investigated that transmits quantum messages from two independent sources to a unique receiver. Several general assertions about the system throughput are proved, and physically important coherent- and squeezed-state transmissions are examined in detail. Some problems of one-source communication in the presence of noise are discussed.
