As in the previous year, the Fraunhofer Heinrich Hertz Institute (HHI) contributed to the online advent calendar of the EU Quantum Flagship Project UNIQORN. Themed "Christmas and Quantum Communication", the advent calendar offers those interested in the topic a daily selection of informative texts, Christmas stories and odd facts about quantum communication.
For the second year in a row, the "Quantum Christmas Calendar" accompanies users through the holiday season with exciting stories and facts about quantum communication. As common for conventional advent calendars, the UNIQORN advent calendar opens or rather activates a new door every day. Behind each of them is a picture and a text that illustrate the important topic of quantum communication. In addition, the individual doors make up a large puzzle whose image is revealed more and more each day. Fraunhofer HHI filled three doors this year. You can find the calendar on the UNIQORN project homepage. Visit the site every day to make sure you don't miss out on any of the exciting stories!
The project "UNIQORN - Affordable Quantum Communication for Everyone: Revolutionizing the Quantum Ecosystem from Fabrication to Application" has set itself the goal of miniaturizing quantum technologies using photonic integration and making them available to users as system-on-chip solutions. Project partners, including the Fraunhofer HHI, will develop the key components for the quantum communications systems of the future, which are needed, among other things, to generate true random numbers and secure key distribution. The components include specialized quantum optical sources and detector technologies implemented on established integration platforms, similar to mass production in microelectronics. They are the basis for highly miniaturized optical systems that can fully exploit quantum mechanical properties such as entanglement and squeezed light.
