A Resource Framework for Quantum Shannon Theory
I. Devetak, A. W. Harrow, A. Winter
Quantum Shannon theory is loosely defined as a collection of coding theorems, such as classical and quantum source compression, noisy channel coding theorems, entanglement distilla…
Entanglement-Assisted Capacity of Quantum Multiple-Access Channels
Min-Hsiu Hsieh, Igor Devetak, Andreas Winter
We find a regularized formula for the entanglement-assisted (EA) capacity region for quantum multiple access channels (QMAC). We illustrate the capacity region calculation with the…
Multiplicativity of completely bounded p-norms implies a new additivity result
Igor Devetak, Marius Junge, Christopher King +1
We prove additivity of the minimal conditional entropy associated with a quantum channel Phi, represented by a completely positive (CP), trace-preserving map, when the infimum of S…
A triangle of dualities: reversibly decomposable quantum channels, source-channel duality, and time reversal
I. Devetak
Two quantum information processing protocols are said to be dual under resource reversal if the resources consumed (generated) in one protocol are generated (consumed) in the other…
Capacity Theorems for Quantum Multiple Access Channels: Classical-Quantum and Quantum-Quantum Capacity Regions
Jon Yard, Igor Devetak, Patrick Hayden
We consider quantum channels with two senders and one receiver. For an arbitrary such channel, we give multi-letter characterizations of two different two-dimensional capacity regi…
