Title: Quantum sensors for space-borne earth observation
Description:
<p>Atom interferometry enables quantum sensors for absolute measurements of gravity (1) and gravity gradients (2).
The combination with classical sensors can be exploited to suppress vibration noise in the interferometer, extend the dynamic range, or to remove the drift from the classical device (3).
These features motivate novel sensor and mission concepts for space-borne earth observation e.
g.
with quantum gradiometers (4) or hybridised atom interferometers (5).
We will discuss developments of atom optics and atom interferometry in microgravity in the context of future quantum sensors (6) and outline the perspectives for applications in space (4,5).
