In Defence Of The Phase Space Picture

Martino Travagnin

This report assesses the potential of gyroscopes and accelerometers based on cold atom interferometry (CAI) for space and defence applications, by analysing their strengths and weaknesses in comparison with devices based on other working principles. Indeed, it is widely recognized that quantum sensors based on atomic interferometry provide absolute measurements with the potential for high sensitivity and long-term stability. This last property is particularly valuable for accelerometers and gyroscopes to be used for inertial navigation, since it guarantees precise positioning without the need for frequent recalibrations, a shortcoming which affects several devices presently in use. \nHigh-performance inertial sensors play an important role both in space applications, where gyroscopes are widely used e.g. to orientate a satellite and its on-board communications and sensing equipment, and in defence, where gyroscopes and accelerometers constitute the core of the inertial measurement units to be used for autonomous navigation, e.g. in GNSS-denied conditions. The EU has a well-established role in space with the Copernicus and Galileo programmes, and a fledging but increasing involvement in the defence industry. An independent assessment of a quantum technology such as cold atom interferometry which may in time acquire a significant role in these fields is a precondition to advance well-grounded suggestions for EU policy initiatives.

This research delves into the nexus between quantum technologies and their prospective role in enhancing secure satellite communications, with a particular focus within the European Union (EU) space security and defence. Embarking on an interpretivist research design, the study employs qualitative content analysis and fieldwork at the European Union Agency for the Space Programme (EUSPA) to elucidate the interplay between quantum principles and the EU's space endeavours. Through an exploration of quantum key distribution via space, the research shows a promising future for the secure transmission of critical data. To harness these quantum advancements effectively, substantial investments within the EU are essential. Against the backdrop of the evolving EU space strategy for security and defence, the research contemplates the centralisation of space matters within a singular, specialized EU body. In the broader context, the study underscores the urgency for international regulations to navigate the burgeoning complexities of space technology advancements and to safeguard against the threats of space weaponization. As the EU navigates unexplored space areas, the combination of quantum innovation, strategic coherence, and international cooperation emerges as crucial in guiding the EU towards a strong...
