Arbitrarily varying and compound classical-quantum channels and a note on quantum zero-error capacities
Igor Bjelaković, Holger Boche, Gisbert Janßen +1
We consider compound as well as arbitrarily varying classical-quantum channel models. For classical-quantum compound channels, we give an elementary proof of the direct part of the…
Universal quantum state merging
Igor Bjelaković, Holger Boche, Gisbert Janßen
We determine the optimal entanglement rate of quantum state merging when assuming that the state is unknown except for its membership in a certain set of states. We find that mergi…
Entanglement Transmission over Arbitrarily Varying Quantum Channels
R. Ahlswede, I. Bjelakovic, H. Boche +1
We derive a regularized formula for the common randomness assisted entanglement transmission capacity of finite arbitrarily varying quantum channels (AVQC's). For finite AVQC's wit…
Entanglement Transmission Capacity of Compound Channels
Igor Bjelakovic, Holger Boche, Janis Noetzel
We determine the optimal achievable rate at which entanglement can be reliably transmitted when the memoryless channel used during transmission is unknown both to sender and receiv…
Entanglement transmission and generation under channel uncertainty: Universal quantum channel coding
I. Bjelakovic, H. Boche, J. Noetzel
We determine the optimal rates of universal quantum codes for entanglement transmission and generation under channel uncertainty. In the simplest scenario the sender and receiver a…
On Quantum Capacity of Compound Channels
I. Bjelakovic, H. Boche, J. Noetzel
In this paper we address the issue of universal or robust communication over quantum channels. Specifically, we consider memoryless communication scenario with channel uncertainty…
