Quantum Limits of LEO Satellite Beacon Reading
Pere Munar-Vallespir, Marc Geitz, Ángeles Vázquez-Castro +1
We study the quantum limits of the ELROI beacon concept introduced by Holmes, Weaver, and Palmer. In this concept, a satellite continuously emits a weak optical signal to broadcast…
A class of permutation-invariant measurements and their relation to quantum relative entropies
Janis Nötzel
We characterize the asymptotic performance of a class of positive operator valued measurements (POVMs) where the only task is to make measurements on independent and identically di…
Arbitrarily Small Amounts of Correlation for Arbitrarily Varying Quantum Channels
Holger Boche, Janis Noetzel
As our main result we show that, in order to achieve the randomness assisted message - and entanglement transmission capacities of a finite arbitrarily varying quantum channel it i…
A solution to two party typicality using representation theory of the symmetric group
Janis Nötzel
We give a proof of the multi-party typicality conjecture for the first nontrivial case when there are only two parties. The conjecture itself is motivated by the study of multi-par…
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…
