highly sensitive atom interferometry

A quantum accelerometer using highly sensitive atom interferometry to measure accelerations along a horizontal axis with applications in satellite-free navigation.

A quantum accelerometer uses atom interferometry to measure accelerations along a horizontal axis. Quantum accelerometers are able to achieve a combination of sensitivity and stability by exploiting quantum interference. As such, they will be critical components of a quantum inertial navigation unit, which will offer satellite-free navigation with unparalleled long-term accuracy. A phase locked SolsTiS system underpins this setup and provides the extremely low phase noise required to make high sensitivity measurements and dynamic frequency tunability to address multiple atomic transitions.
