Workshop Chairs

Christian Deppe, Janis Nötzel (TUM)

Local Organization

Roberto Ferrara, Uzi Pereg, Stepehn Di Adamo, Christin Wizemann, Robert Schetterer

Topics of Interest

Will quantum communication reshape classical network design? What will be the next technological breakthrough in quantum communication? This interdisciplinary workshop focusses on entanglement as a resource assisting classical communication systems. We welcome participants from academic institutions, research labs and industry. Selected approaches to entanglement-assisted communication will be presented, along with established communication models in classical networking. To spark fruitful discussions, information regarding the progress in quantum hardware development will be provided.

Treffen der Q.Link.X-Theoriegruppe in Berlin

Die Theoriegruppe von Q.Link.X begleitet experimentelle Implementierungen. Insbesondere entwickelt sie eine Simulationsplattform, die es erlaubt, realistische Schemata für Quantenrepeater für experimentell relevante Parameter zu erproben und zu vergleichen. Auch werden Methoden ausgelotet zur Charakterisierung von Komponenten von Quantenrepeatern. Am 7. Oktober 2019 traf sich die Theoriegruppe in Berlin, um über Fortschritte zu berichten und neue gemeinsame Schritte zu skizzieren.

Summer school – Quantum devices for non-classical light generation and manipulation

Welcome to the first edition of the graduate summer school “Quantum devices for non-classical light generation and manipulation”.

The summer school will cover different aspects of quantum technology, from quantum information and communication, to quantum computation and sensing. Different systems will be discussed, i.e. quantum dots, color centers in diamond, organic molecules, integrated quantum photonics and cold atoms and ions, from applied to more fundamental research.

The summer school will be held in the beautiful Erice, guested by the “Ettore Majorana foundation and centre for scientific culture”, from September the 30th to October the 5th.

Physikalische und industrielle Anforderungen an zukünftige Quantennetzwerke

Workshop des Q.Link.X-Verbundprojektes

Braunschweig 23./24. Januar 2019

Datensicherheit und die nachweisbar sichere Kommunikation gewinnen kontinuierlich an Bedeutung. Quantenkommunikation bietet dafür im Rahmen der schnell wachsenden Quantentechnologien einen neuen Lösungsansatz, der auf den Grundprinzipien der Quantenphysik aufbaut, indem Quantenzustände als Informationsträger eingesetzt werden, die aufgrund fundamentaler physikalischer Gesetze weder kopiert noch mitgelesen werden können.
