On the error analysis of quantum repeaters with encoding
Michael Epping, Hermann Kampermann, Dagmar Bruß
Losses of optical signals scale exponentially with the distance. Quantum repeaters are devices that tackle these losses in quantum communication by splitting the total distance int…
Determining X-chains in graph states
Jun-Yi Wu, Hermann Kampermann, Dagmar Bruß
The representation of graph states in the X-basis as well as the calculation of graph state overlaps can efficiently be performed by using the concept of X-Chains [Phys. Rev. A 92(…
Detecting Entanglement of Unknown Quantum States with Random Measurements
Jochen Szangolies, Hermann Kampermann, Dagmar Bruß
In quantum information theory, the reliable and effective detection of entanglement is of paramount importance. However, given an unknown state, assessing its entanglement is a cha…
Large-scale quantum networks based on graphs
Michael Epping, Hermann Kampermann, Dagmar Bruß
Society relies and depends increasingly on information exchange and communication. In the quantum world, security and privacy is a built-in feature for information processing. The…
Witnessing entanglement by proxy
Stefan Bäuml, Dagmar Bruß, Marcus Huber +2
Entanglement is a ubiquitous feature of low temperature systems and believed to be highly relevant for the dynamics of condensed matter properties and quantum computation even at h…
Group structures and representations of graph states
Jun-Yi Wu, Hermann Kampermann, Dagmar Bruß
A special configuration of graph state stabilizers, which contains only Pauli operators, is studied. The vertex sets associated with such configurations are defined as wh…
