Advances in Technological Quantum Optics

Commonly used classical cryptographic protocols, such as the RSA-protocol, rely on the hardness of computational problems. With the advent of quantum computing (QC), the hardness assumptions of these problems is nullified, since they can be solved efficiently on a QC. On the other hand, the security of Quantum key distribution (QKD) rests upon the very laws of physics and guarantees information-theoretic security, which not only enables tap-proof communication at present, but also prevents any future technology to crack encrypted messages.

On the Use of Mega-Constellation Services in Space

On the Use of Mega-Constellation Services in Space, funded by ESA’s Open Space Innovation Platform (OSIP), investigates how mega-constellations can be used to provide low-Earth orbit (LEO) spacecraft with broadband low-latency services, a novel Concept with potential to disrupt spacecraft design, operation, and performance by allowing spacecraft to access mega-constellations’ enormous resources (Tbit/s throughputs) and global coverage at a lower cost than traditional data relay systems and ground station networks (two to fifty times cheaper, that is, a few hundred to a few thousand dollars

Novel estimation of shallow water bathymetry using ICESat-2 laser altimetry, signal processing and machine learning and Sentinel-2 optical data in a highly automated approach

The project “Novel estimation of shallow water bathymetry using ICESat-2 laser altimetry, signal processing and machine learning and Sentinel-2 optical data in a highly automated approach” was funded under the European Space Agencies’ Open Space Innovation Platform (OSIP). The overall objective was to build a self-calibrating and efficient bathymetry mapping system by leveraging accurate and consistent ICESat-2 laser altimeter data as a calibration source for high-resolution Copernicus Sentinel-2 based water depth retrievals.

Study into Ultra-Wide-Band SAR Tomography over Dry, Rocky Terrains

In recent years, surface-penetrating radars have formed a part of several ESA missions in both monostatic and bi-static configurations. Such radars can be found, for instance, on board Mars Express where, using MARSIS the Martian sub-surface is sensed, as well as on board Rosetta where CONSERT has been used to probe the comet 67P/Churyumov-Gerasimenko. In addition, surface-penetrating radars are being implemented for the JUICE mission to Jupiter’s moons Ganymede and Europa.
