I discuss the transmission of classical information via quantum carriers with focus on the decoding stage. While the optimal transmission rate and encoding have been well studied in the past providing viable solutions for free-space or optical-fiber communication, a practical decoder is still difficult to design. This is due to the requirement of performing joint measurements over several transmission modes and their difficult implementation with current technology. I approach the problem from several points of view presenting ideas for decoding algorithms and practical devices, in particular for communication with coherent states of the electromagnetic field.
