Description
Atom interferometers are a form of quantum sensor in which matter waves are used for high-precision inertial sensing, such as gravimetry and gradiometry. Optimizing these sensors involves a careful design of the interferometer geometry, as well as improving the detection scheme that monitors internal and center-of-mass states of an atomic cloud.
In this talk we present a theoretical analysis of an advanced experimental detection scheme for the D2-line of 87 Rb atoms, which consists of a sequence of laser beams. The interaction between the atoms and beams is described using a master equation, which is solved numerically using a quantum jump approach. Each quantum jump takes into account the interplay between hyperfine state and the momentum kick that an atom receives when emitting a photon. We present simulations of the detection scheme and discuss how it can impact both the sensitivity and accuracy of existing atom interferometers.
