Optical Technologies for Connectivity and Secure Communications

Josep Perdigués Armengol, Güray Açar, Niklas Lindman +5 more

The European Space Agency (ESA) has systematically supported European / Canadian industries (more than 30 years) in developing cutting-edge optical technologies for optical communications and quantum communications. ESA created in 2016 the dedicated ScyLight Strategic Programme Line (part of the ESA Telecommunications ARTES programme) to focalize these efforts. Besides the research and development of optical and quantum communication technologies, ScyLight funds flight opportunities for their in-orbit verification. In this respect, the two main initiatives are “High thRoughput Optical Network” (HydRON) and “Security And cryptographic” (SAGA) projects, which respectively paves the way towards the first terabit/sec capacity optical satellite network and contributes to the creation of a highly secure pan-European quantum communication infrastructure.

Entanglement-based QKD over LEO satellite-to-ground time-varying atmospheric channel

Argiris Ntanos, Nikolaos K. Lyras, Aristeidis Stathis +4 more

For enabling and realizing long-haul Quantum Key Distribution (QKD), satellite communication infrastructure is exploited to deliver symmetric encryption keys to ground segments. In this direction the European Quantum Communication Infrastructure (Euro-QCI) initiative, supported by the European Space Agency (ESA), aims to build a secure quantum communication network that will span across the EU. In this framework, ESA has selected three observatories in Greece to support European activities in optical communications and QKD systems. In this study, a QKD feasibility analysis between a LEO satellite constellation (100 satellites) and the three selected Optical Ground Stations (OGSs) in Greece, using an entangled based QKD protocol is presented. This contribution focuses on the performance evaluation and the applicability validation of an entanglement-based QKD system in a pragmatic regional segment of Euro-QCI. The time varying atmospheric channel is modeled taking into account the joint cloud coverage of the OGSs, the turbulence, the pointing errors and the solar background radiance. The performance of the regional entangled-based QKD system is validated in terms of annual availability as well as the number of shared distilled key bits between the ground stations per year.

The study of Quantum Physics in Space Technology

Shravani Raju Rupwate

Quantum physics has transitioned from a purely theoretical discipline to a transformative technological foundation influencing modern space science and engineering. From ultra-precise atomic clocks enabling global navigation systems to quantum sensors enhancing spacecraft navigation and quantum communication networks promising unbreakable encryption, quantum mechanics now plays a pivotal role in space technology. This research paper explores the theoretical foundations of quantum physics and examines its applications in satellite systems, deep-space exploration, communication networks, gravitational sensing, propulsion research, and cosmology. It further discusses current missions led by agencies such as NASA, European Space Agency, and China National Space Administration, highlighting advancements in space-based quantum experiments. The paper concludes with future prospects, technical challenges, and the role of quantum technology in shaping next-generation space exploration.
