Boost for the Quantum Internet

QCI-CAT partner University of Innsbruck published a paper in which they describe the success of demonstrating a quantum repeater node at telecom wavelengths. This finding has huge potential for realizing the so-called quantum internet and quantum key distribution over long distances (up to 800km, which would allow an entanglement distribution from Vienna to Innsbruck).

The quantum team under the supervision of Ben Lanyon, a theoretical physicist at the Department of Experimental Physics and a close associate to QCI-CAT, will use these results in the QCI-CAT project and hence help to demonstrate a QKD distribution on a pure quantum level.

ABOUT QCI-CAT

Building on the long research experience of Austrian institutions in the field of quantum technologies, the project QCI-CAT aims at an adoption of modern encryption technology based on QKD for highly secure communication between public authorities.

QCI-CAT will investigate and verify new security applications for public authorities, such as secret sharing and message authentication.

Additionally, QCI-CAT will also leverage a research testbed for new technological approaches such as the combination of post-quantum encryption with QKD, long-distance QKD with secured trusted nodes and field trials of quantum repeaters.

This project has received funding from the DIGITAL-2021-QCI-01 Digital European Program under Project number No 101091642 and the National Foundation for Research, Technology and Development.
