European nations are investing in quantum technology (QT) commercialization for secure communication and computing. This summary outlines the state of QT for space applications, proposing a framework for its development and use.
Area of Science:
- Quantum Technology
- Space Applications
- European Research Initiatives
Background:
- European Commission and member states are heavily investing in quantum technology (QT) commercialization.
- QT development has progressed for over two decades, promising breakthroughs in secure communication and computing.
- Individual national efforts are insufficient; a coordinated European approach is needed, akin to Galileo or Copernicus programs.
Purpose of the Study:
- To summarize the current state of quantum technology development relevant to space applications.
- To propose a comprehensive framework for designing, developing, implementing, and exploiting QT in space.
Main Methods:
- Review of state-of-the-art quantum technologies.
- Analysis of European investments and initiatives in QT.
- Development of a strategic framework for space-based QT.
Main Results:
- Identification of key quantum technologies with potential for space applications.
- Assessment of the need for a unified European strategy in space QT.
- Outline of a framework for QT integration into space missions.
Conclusions:
- A coordinated European effort is crucial for advancing quantum technology in space.
- The proposed framework will guide the development and exploitation of space-based QT.
- Quantum technology holds significant promise for future space communication and sensing capabilities.

This has been verified in many experiments. However, space and time are no longer absolute. Two observers moving relative to one another do not agree on the length of objects or the passage of time. The mechanics of objects based on Newton's laws of...

Electromagnetic Waves in Matter
Consider the electromagnetic wave passing through a dielectric medium. In such a case, Maxwell's equations get modified. In Ampere's law, ε0 , the dielectric permittivity of free space is replaced with ε, the permittivity of dielectric. Also, the vacuum permeability μ0 is replaced by the permeability of the...
