Secret Message Transmission over Quantum Channels under Adversarial Quantum Noise: Secrecy Capacity and Super-Activation
Holger Boche, Minglai Cai, Christian Deppe +1
We determine the secrecy capacities of AVQCs (arbitrarily varying quantum channels). Both secrecy capacity with average error probability and with maximal error probability are der…
Reliable Communication under the Influence of a State-Constrained Jammer: A Novel Perspective on Receive Diversity
Christian Arendt, Janis Nötzel, Holger Boche
The question of robust direct communication in vehicular networks is discussed. In most state-of-the-art approaches, there is no central entity controlling channel access, so there…
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…
Classical-Quantum Arbitrarily Varying Wiretap Channel: Secret Message Transmission under Jamming Attacks
Holger Boche, Minglai Cai, Christian Deppe +1
We analyze arbitrarily varying classical-quantum wiretap channels.These channels are subject to two attacks at the same time: one passive (eavesdropping), and one active (jamming).…
