Universal superposition codes: capacity regions of compound quantum broadcast channel with confidential messages
Holger Boche, Gisbert Janßen, Sajad Saeedinaeeni
We derive universal codes for transmission of broadcast and confidential messages over classical-quantum-quantum and fully quantum channels. These codes are robust to channel uncer…
Simultaneous transmission of classical and quantum information under channel uncertainty and jamming attacks
Holger Boche, Gisbert Janßen, Sajad Saeedinaeeni
We derive universal codes for simultaneous transmission of classical messages and entanglement through quantum channels, possibly under attack of a malignant third party. These cod…
Universal random codes: Capacity regions of the compound quantum multiple-access channel with one classical and one quantum sender
Holger Boche, Gisbert Janßen, Sajad Saeedinaeeni
We consider the compound memoryless quantum multiple-access channel (QMAC) with two sending terminals. In this model, the transmission is governed by the memoryless extensions of a…
Randomness cost of symmetric twirling
Holger Boche, Gisbert Janßen, Sajad Saeedinaeeni
We study random unitary channels which reproduce the action of the twirling channel corresponding to the representation of the symmetric groupon an n-fold tensor product. We derive…
Entanglement-assisted classical capacities of compound and arbitrarily varying quantum channels
Holger Boche, Gisbert Janßen, Stephan Kaltenstadler
We consider classical message transmission under entanglement assistance for compound memoryless and arbitrarily varying quantum channels. In both cases, we prove general coding th…
Distillation of secret key from a class of compound memoryless quantum sources
Holger Boche, Gisbert Janßen
We consider secret-key distillation from tripartite compound classical-quantum-quantum (cqq) sources with free forward public communication under strong security criterion. We desi…
Resource Cost Results for Entanglement Distillation and State Merging under Source Uncertainties
Holger Boche, Gisbert Janßen
We introduce one-way LOCC protocols for quantum state merging for compound sources, which have asymptotically optimal entanglement as well as classical communication resource costs…
Resource cost results for one-way entanglement distillation and state merging of compound and arbitrarily varying quantum sources
Holger Boche, Gisbert Janßen
We consider one-way quantum state merging and entanglement distillation under compound and arbitrarily varying source models. Regarding quantum compound sources, where the source i…
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…
