Quantum Sensors leverage the pristine stability of the internal structure of an alkali atom (such as Rubidium) to make measurements of local fields (electric, magnetic), forces (acceleration, rotation), and time (atomic clock).
PSI has recently developed novel 3D-printing Technology of Vacuum Components for atom-based quantum sensors. The technology removes the constraints of traditional manufacturing, enabling several advanced features that ultimately reduce SWaP and allow complex geometries.
We have recently reached a vacuum base-pressure below 10-9 Torr and demonstrated the production of an ultra-cold atomic cloud in such a 3D-printed chamber.
