Scientific Rigor and Human Warmth: Remembering Vladimir Sidorenko (1949-2025)

Christian Deppe, Haider Al Kim, Jessica Bariffi +4

During the Foundations of Future Communication Systems (FFCS) conference in Braunschweig, a dedicated memorial session was held in honor of Dr. Vladimir (Volodya) Sidorenko (1949-2…

Quantum Byzantine Multiple Access Channels

Minglai Cai, Christian Deppe

In communication theory, attacks like eavesdropping or jamming are typically assumed to occur at the channel level, while communication parties are expected to follow established p…

Quantum Wiretap Channel Coding Assisted by Noisy Correlation

Minglai Cai, Andreas Winter

We consider the private classical capacity of a quantum wiretap channel, where the users (sender Alice, receiver Bob, and eavesdropper Eve) have access to the resource of a shared…

Mosaics of Combinatorial Designs for Semantic Security on Quantum Wiretap Channels

Holger Boche, Minglai Cai, Moritz Wiese

We study semantic security for classical-quantum channels. Our security functions are functional forms of mosaics of combinatorial designs. We extend methods for classical channels…

Semantic Security for Quantum Wiretap Channels

Holger Boche, Minglai Cai, Christian Deppe +2

We consider the problem of semantic security via classical-quantum and quantum wiretap channels and use explicit constructions to transform a non-secure code into a semantically se…

Message Transmission over Classical Quantum Channels with a Jammer with Side Information: Correlation as Resource, Common Randomness Generation

Holger Boche, Minglai Cai, Ning Cai

In this paper we analyze the capacity of a general model for arbitrarily varying classical-quantum channels (AVCQCs) when the sender and the receiver use correlation as a resource.…

Message Transmission over Classical Quantum Channels with a Jammer with Side Information: Message Transmission Capacity and Resources

Holger Boche, Minglai Cai, Ning Cai

In this paper we propose a new model for arbitrarily varying classical-quantum channels. In this model a jammer has side information. We consider two scenarios. In the first scenar…

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…

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).…

Broadcast Classical-Quantum Capacity Region of Two-Phase Bidirectional Relaying Channel

Holger Boche, Minglai Cai, Christian Deppe

We study a three-node quantum network which enables bidirectional communication between two nodes with a half-duplex relay node. A decode-and-forward protocol is used to perform th…

Classical-Quantum Arbitrarily Varying Wiretap Channel: Ahlswede dichotomy, Positivity, Resources, Super Activation

Holger Boche, Minglai Cai, Christian Deppe +1

We establish Ahlswede dichotomy for arbitrarily varying classical-quantum wiretap channels. This means that either the deterministic secrecy capacity of an arbitrarily varying clas…

Secrecy capacities of compound quantum wiretap channels and applications

Holger Boche, Minglai Cai, Ning Cai +1

We determine the secrecy capacity of the compound channel with quantum wiretapper and channel state information at the transmitter. Moreover, we derive a lower bound on the secrecy…

Capacities of classical compound quantum wiretap and classical quantum compound wiretap channels

Minglai Cai, Ning Cai, Christian Deppe

We determine the capacity of the classical compound quantum wiretapper channel with channel state information at the transmitter. Moreover we derive a lower bound on the capacity o…
