A review on super dense coding over covariant noisy channels

Zahra Shadman, Hermann Kampermann, Chiara Macchiavello +1

We study the performance of the super dense coding protocol in the presence of quantum channels with covariant noise. We first consider the bipartite case and review in a unified w…

Distributed super dense coding over noisy channels

Zahra Shadman, Hermann Kampermann, Chiara Macchiavello +1

We study multipartite super dense coding in the presence of a covariant noisy channel. We investigate the case of many senders and one receiver, considering both unitary and non-un…

Quantum key distribution with finite resources: Taking advantage of quantum noise

Markus Mertz, Hermann Kampermann, Zahra Shadman +1

We compare the effect of different noise scenarios on the achievable rate of an epsilon-secure key for the BB84 and the six-state protocol. We study the situation where quantum noi…

Optimal super dense coding over memory channels

Zahra Shadman, Hermann Kampermann, Chiara Macchiavello +1

We study the super dense coding capacity in the presence of quantum channels with correlated noise. We investigate both the cases of unitary and non-unitary encoding. Pauli channel…

Optimal super dense coding over noisy quantum channels

Zahra Shadman, Hermann Kampermann, Chiara Macchiavello +1

We investigate super dense coding in the presence of noise, i.e. the subsystems of the entangled resource state have to pass a noisy unital quantum channel between the sender and t…

Optimal eavesdropping on noisy states in quantum key distribution

Z. Shadman, H. Kampermann, T. Meyer +1

We study eavesdropping in quantum key distribution with the six state protocol,when the signal states are mixed with white noise. This situation may arise either when Alice deliber…
