To gain better understanding of the upper atmospheric dynamics requires more accurate determination of the mass density distribution in the thermosphere. Improved measurements of drag, by means of satellite accelerometery, can be used to more precisely determine this distribution. In addition, atmospheric drag in Low Earth Orbit (LEO) is particularly of interest for climate modelling, weather...
Poster will give an overview of three current projects undergoing at Fraunhofer CAP. One project is based on satellite based Quantum Key Distribution (QKD) encoded communication to be packaged in a compact, robust and commercially-viable form. More details in a second project on photon entanglement with different sources for space applications. Finally, a quick overview of the project in...
The decoy state technique in quantum key distribution (QKD) has been proven as the most optimal strategy to counter photon number splitting (PNS) attacks. In the asymptotic limit of running the experiment an infinite time, it was shown that 2-decoy outperforms 1-decoy protocol. However, it was also showed that 1-decoy reached higher key rates than 2-decoy for finite block sizes except for...
The development of cubic optical cavities for high TRL low SWaP stabilization of laser light for applications in the space sector, such as fundamental physics, Earth observation and future navigation, will be presented.
In the drive to develop cold-atom quantum technologies, compact vacuum systems are key to enabling quantum sensing for real world applications. These vacuum systems not only have to be reduced in size, weight, and power compared to their traditional counterparts, but face other challenges.
Eliminating active pumping addresses both size and power, but introduces the issue of helium gas...
