In the spirit of Shannon's information theory 1, any physical process acting on a quantum system can be thought of as a communication channel. One may then speak of its capacity for transmitting ...
The identities or bounds that relate information measures (e.g., the entropy and mutual information) and estimation measures (e.g., the minimum means square error ...
Study of the capacity of additive channels with an amplitude constrain (i.e., peak power) on the input. Amplitude constrained channels commonly occur in practice, however, neither capacity nor optimal ...
