A method for atom-based closed-loop control includes exciting atoms of a gas into one or more Rydberg states, applying one or more signal processing functions to the one or more Rydberg states, and regulating a characteristic of the applied one or more signal processing functions based on, at...

The laser system presented here is an entirely commercial device that can be adapted to atom interferometer experiments using atomic rubidium, as well as potassium80and cesium81. These systems can be made more mobile and compact74for applications outside the laboratory; with the addition of micro-...
The two remaining magnetic gradients required to complete such a “closed” SGI are discussed in the following section. 5 Full-Loop Stern-Gerlach Interferometer Clearly, if a wavepacket can be coherently reconstructed after SG splitting and recombination in a four-field configuration [26], it ...
We demonstrate a proof-of-principle of direct Earth gravity-gradient measurement with an atom interferometer-based gravity gradiometer using a single proof mass of cold Rb87 atoms. The atomic gradiometer is implemented in the so-called double-loop configuration, hence providing a direct gravity-gradie...

We hand over control of these ramps to the MLOO. We consider two parameterizations: one simple, where we only control the start and end points of a linear interpolation; and one complex, where we add variable quadratic, cubic and quartic corrections to the simple case (see Supplemental ...
an interference path and a detector.The interferometer includes atomic vapor having a first atomic state and a second atomic state.An interference path from the RF phase between the first and second atomic states is closed by the quantum state space.The detector is configured to detect the readin...
Perturbing the phase around 0° with 𝐼𝐿=𝐼𝑅IL=IR, one can separate opposite polarization traps vertically from co-location, but the trap frequencies differ and must be compensated for in an interferometer scheme. Additionally, this phase control scheme can co-locate one polarization’s ...
