In light pulse atom interferometry wave packets are spatially separated and recombined in a coherent manner by interacting with laser pulses. Typically, two photon transitions are used to perform Rabi oscillations between ...

Entangled ensembles have been created in versatile atomic systems and find a promising application in entanglement-enhanced metrology. Here, entangled spin-states have been successfully applied within interferometers ...

With the introduction of portable atom interferometers (AI), a genuinely independent method for the determination of g is available for the first time since the introduction of laser interferometer based instruments. Current ...

Quantum sensors based on atom interferometry are precise measurement devices whose ultimate performance can be reached using Bose–Einstein condensates (BECs) in extended free fall. This thesis summarizes the endeavour of ...

In the past century, the development of gravimeters with low uncertainty and long-term stability has led to new fields of research in geodesy and geoscience. Decreasing the instrumental measurement uncertainty further will ...
