Quantum Information is whatever can be transmitted by using systems obeying Quantum Theory as carriers. The basic questions of this theory are taken from classical information theory: how much “quantum information” is carried by any given system or transmission channel, how much is stored in a storage device, how can such information be coded and decoded efficiently etc.
