Inequalities and separations among assisted capacities of quantum channels
Charles H. Bennett, Igor Devetak, Peter W. Shor +1
We exhibit discrete memoryless quantum channels whose quantum capacity assisted by two-way classical communication, , exceeds their unassisted one-shot Holevo capacity .…

The classical capacity achievable by a quantum channel assisted by limited entanglement
Peter W. Shor
We give the trade-off curve showing the capacity of a quantum channel as a function of the amount of entanglement used by the sender and receiver for transmitting information. The…
