Bounds on quantum conference key agreement in pair-entangled networks
Justus Neumann, Hermann Kampermann, Dagmar Bruß +1
We investigate the task of conference key agreement in near-term quantum networks, where the nodes are connected by sources of bipartite entangled states, under the class of local…
Spanning-tree-packing protocol for conference key propagation in quantum networks
Anton Trushechkin, Hermann Kampermann, Dagmar Bruß
We consider a network of users connected by pairwise quantum key distribution (QKD) links. Using these pairwise secret keys and public classical communication, the users want to ge…
Multiplexed multipartite quantum repeater rates in the stationary regime
Julia A. Kunzelmann, Anton Trushechkin, Nikolai Wyderka +2
Multipartite quantum repeaters play an important role in quantum communication networks enabling the transmission of quantum information over larger distances. To increase the rate…
Quantum mechanics based on real numbers: A consistent description
Pedro Barrios Hita, Anton Trushechkin, Hermann Kampermann +2
Complex numbers play a crucial role in quantum mechanics. However, their necessity remains debated: whether they are fundamental or merely convenient. Recently, it was shown that a…
