AQUnet will establish an Austria-wide glass fiber network for the distribution of quantum information and quantum metrology signals. The existing data backbone infrastructure, operated by ACOnet (Austrian Academic Computer Network), will be upgraded and extended to enable safe and stable transport of quantum signals. Within AQUnet, we will connect a series of locations of the consortium in Vienna and Innsbruck, as well as external users. We will furthermore connect to partnering European initiatives like e.g. REFIMEVE+ (France), PTB-LMU (Germany), ISI-Brno (Czech Republic).
AQUnet will enable ACOnet (with support by project partners and the scientific community) to extend the existing data infrastructure to quantum signals: where possible, “classical” glass fiber channels will be upgraded used for simultaneous quantum transport, existing dark fibers will be made accessible, new channels established. The notoriously fragile quantum signals will require specific amplification stages (especially along Innsbruck-Vienna). A central node for the star-shaped distribution of an ultrastable optical reference signal (linked to the Austrian primary atomic clock at the federal office for calibration and surveying BEV) will be established.

In Bristol, researchers in cooperation with IQOQI-Vienna (Austrian Academy of Sciences) have built a network that allows quantum-encrypted communication between eight participants. The breakthrough is the key that is generated
