Collaborative Study – Quantum Technologies and Space

This study, conducted by the European Patent Office, European Space Policy Institute, and European Space Agency, analyzes global patent trends related to the application of quantum technologies in the space industry from 2001 to 2020. While both quantum and space technologies are strategically important for major global powers and the European Union, the specific use of quantum technologies in space applications is growing rapidly. The primary uses of quantum technologies in space include secure communications, time and frequency transfer, and Earth sensing and observation. The study focuses on three key quantum technologies enabling these applications: quantum key distribution, cold atom clocks, and cold atom interferometers. The analysis reveals a significant increase in patent filings related to space applications of quantum technologies, driven mainly by innovation in quantum key distribution. Despite this growth, space-related quantum technology innovations primarily originate from the US and China, indicating a high level of specialization and limited synergies. Europe, while recognizing the potential of quantum technologies in space, is not yet a leader in this field but with the introduction of initiatives like EuroQCI, there is potential for growth and innovation in the future.
