| Résumé : | Situations in which Alice and Bob wish to use noiseless classical information to offset quantum noise are considered. An important feature is that Alice possesses a classical description of the quantum states she wishes to send. After considering these situations in generality, a very specific scenario in which Alice sends one qubit that passes through a depolarizing channel accompanied by a noiseless classical bit is considered. A scheme that involves Alice dividing up the Bloch sphere as in assumption 1 and Bob performing amplitude damping operations is described. |
