Query: Quantum Zero-error Capacity   We define here a new kind of quantum channel capacity by extending the
concept of zero-error capacity for a noisy quantum channel. The necessary
requirement for which a quantum channel has zero-error capacity greater than
zero is given. Finally, we point out some directions on how to calculate the
zero-error capacity of such channels.
