“…Since pioneering experiments in 1991 [1][2][3][4][5] , the field of atom interferometry has constantly grown, with an acceleration in the last 10 years. Cold-atom inertial sensors based on light-pulse atom interferometry have reached sensitivity and accuracy levels competing with or beating inertial sensors based on different technologies.…”

The research on cold-atom interferometers gathers a large community of about 50 groups worldwide both in the academic and now in the industrial sectors. The interest in this sub-field of quantum sensing and metrology lies in the large panel of possible applications of cold-atom sensors for measuring inertial and gravitational signals with a high level of stability and accuracy. This review presents the evolution of the field over the last 30 years and focuses on the acceleration of the research effort in the last 10 years. The article describes the physics principle of cold-atom gravito-inertial sensors as well as the main parts of hardware and the expertise required when starting the design of such sensors. It then reviews the progress in the development of instruments measuring gravitational and inertial signals, with a highlight on the limitations to the performances of the sensors, on their applications, and on the latest directions of research.

“…Setup.-Our experiment is based on what is, to the best of our knowledge, the first full-loop SGI realization [11], as originally envisioned [5,6]. Different from previous realizations of the SG effect [32,33], it uses four mag- . Also shown are the π/2 and π RF (light blue) and magnetic gradient splitting, stopping, reversing and recombining pulses (light red).…”

We present a unique matter-wave interferometer whose phase scales with the cube of the time the atom spends in the interferometer. Our scheme is based on a full-loop Stern-Gerlach interferometer incorporating four magnetic field gradient pulses to create a state-dependent force. In contrast to typical atom interferometers which make use of laser light for the splitting and recombination of the wave packets, this realization uses no light and can therefore serve as a high-precision surface probe at very close distances.

“…We briefly compare our experiments to state-of-the-art SG interferometry ( 29 – 39 ). While these longitudinal beam experiments did show spin population interference fringes, the experiments presented here are very different.…”

Realization of a complete Stern-Gerlach interferometer: Toward a test of quantum gravity

The Stern-Gerlach effect, found a century ago, has become a paradigm of quantum mechanics. Unexpectedly, until recently, there has been little evidence that the original scheme with freely propagating atoms exposed to gradients from macroscopic magnets is a fully coherent quantum process. Several theoretical studies have explained why a Stern-Gerlach interferometer is a formidable challenge. Here, we provide a detailed account of the realization of a full-loop Stern-Gerlach interferometer for single atoms and use the acquired understanding to show how this setup may be used to realize an interferometer for macroscopic objects doped with a single spin. Such a realization would open the door to a new era of fundamental probes, including the realization of previously inaccessible tests at the interface of quantum mechanics and gravity.
