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…
The capacity of a quantum channel for simultaneous transmission of classical and quantum information
I. Devetak, P. W. Shor
An expression is derived characterizing the set of admissible rate pairs for simultaneous transmission of classical and quantum information over a given quantum channel, generalizi…
Randomizing quantum states: Constructions and applications
Patrick Hayden, Debbie Leung, Peter W. Shor +1
The construction of a perfectly secure private quantum channel in dimension d is known to require 2 log d shared random key bits between the sender and receiver. We show that if on…
