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 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…
Relating quantum privacy and quantum coherence: an operational approach
Igor Devetak, Andreas Winter
We describe how to achieve optimal entanglement generation and one-way entanglement distillation rates by coherent implementation of a class of secret key generation and secret key…
Distillation of secret key and entanglement from quantum states
Igor Devetak, Andreas Winter
We study and solve the problem of distilling secret key from quantum states representing correlation between two parties (Alice and Bob) and an eavesdropper (Eve) via one-way publi…
The private classical capacity and quantum capacity of a quantum channel
I. Devetak
A formula for the capacity of a quantum channel for transmitting private classical information is derived. This is shown to be equal to the capacity of the channel for generating a…
Towards a unification of physics and information theory
I. Devetak, A. E. Staples
A common framework for quantum mechanics, thermodynamics and information theory is presented. It is accomplished by reinterpreting the mathematical formalism of Everett's many-worl…
