Relativistic Quantum Metrology: Exploiting relativity to improve quantum measurement technologies

Understand

We present a framework for relativistic quantum metrology that is useful for both Earth-based and space-based technologies.

• Quantum metrology has been so far successfully applied to design precision instruments such as clocks and sensors which outperform classical devices by exploiting quantum properties.
• There are advanced plans to implement these and other quantum technologies in space, for instance Space-QUEST and Space Optical Clock projects intend to implement quantum communications and quantum clocks at regimes where relativity starts to kick in.
• However, typical setups do not take into account the effects of relativity on quantum properties.
