Quantum sensors with matter waves for GW observation

Understand

Quantum sensors exploiting matter waves interferometry promise to realize a new generation of Gravitational Wave detectors.

• The intrinsic stability of specific atomic energy levels makes atom interferometers and clocks ideal candidates to extend the frequency window for the observation of Gravitational Waves in the mid-frequency band, ranging from 10 mHz to 10 Hz.
• We present the geometry and functioning of this new class of ground and space detectors and detail their main noise sources.
• We describe the different projects undertaken worldwide to realize large scale demonstrators and push further the current limitations.
