MINI SATELLITE WANTS TO TAKE QUANTUM COMMUNICATION TO SPACE When Alice and Bob talk to each other, no one is listening. No overhearing, no eavesdropping. How is that possible? Alice and Bob are transmission and receiver units. They use quantum key distribution (QKD) for total confidentiality. Researchers from Jena, Würzburg and Potsdam have successfully developed a design for the smallest system of its kind so far to take this highly secure quantum communication to space. Led by Fraunhofer IOF, the project CubEniK developed an ultracompact payload for a satellite the size of a shoe box, a so called “CubeSat”. The goal of the mini satellite is to transmit a secure quantum key over a distance of 300 kilometers between two ground stations in Jena and Munich. The 256 bits long key sent between the ground station could serve as a master key in high-security modules and thereby ensure data sovereignty in sensitive areas such as the financial industry or governmental authorities. 👉 Learn more about the payload design for a CubeSat here: https://lnkd.in/eYbizM2g Apart from Fraunhofer IOF, the CubEniK research consortium consists of two Fraunhofer spin-offs – Quantum Optics Jena GmbH and SPACEOPTIX GmbH – as well as the Center for Telematics (Zentrum für Telematik e.V.) in Würzburg and DiGOS Potsdam GmbH.
