“…Besides the improvement of these Sagnac interferometers using atoms in free fall, the development of confined ultra-cold atomic sources opens the way for new types of matter-wave Sagnac interferometers in which the atoms are sustained or guided [36,37]. Under these conditions, the interrogation time should no longer be limited by the free-fall time of the atoms in the vacuum system, and larger interferometer areas can be achieved.…”

Since the first atom interferometry experiments in 1991, measurements of rotation through the Sagnac effect in open-area atom interferometers has been studied. These studies have demonstrated very high sensitivity which can compete with state-of-the-art optical Sagnac interferometers. Since the early 2000s, these developments have been motivated by possible applications in inertial guidance and geophysics. Most matter-wave interferometers that have been investigated since then are based on two-photon Raman transitions for the manipulation of atomic wave packets. Results from the two most studied configurations, a space-domain interferometer with atomic beams and a time-domain interferometer with cold atoms, are presented and compared. Finally, the latest generation of cold atom interferometers and their preliminary results are presented.

“…We can, for example, design arrays of potential wells for quantum information processing, 74 traps for measuring accelerations, 75 and toroidal waveguides for detecting rotations. [76][77][78][79] The coherent beam splitting of a cold thermal cloud has already been demonstrated for propagating atoms. 80 On atom chips, the coherent manipulation of Bose-Einstein-condensed trapped and propagating atoms has been observed in atom interferometers [81][82][83][84] and atomic clocks.…”

This work reviews the topic of rotation sensing with compact cold atom interferometers. A representative set of compact free-falling cold atom gyroscopes is considered because, in different respects, they establish a rotation-measurement reference for cold guided-atom technologies. The review first discusses enabling technologies relevant to a set of key functional building blocks of an atom chip-based compact inertial sensor with cold guided atoms. These functionalities concern the accurate and reproducible positioning of atoms to initiate a measurement cycle, the coherent momentum transfer to the atom wave packets, the suppression of propagation-induced decoherence due to potential roughness, the on-chip detection, and the vacuum dynamics because of its impact on the sensor stability, which is due to measurement dead time. Based on the existing enabling technologies, the design of an atom chip gyroscope with guided atoms is formalized using a design case that treats design elements such as guiding, fabrication, scale factor, rotation-rate sensitivity, spectral response, important noise sources, and sensor stability. arXiv:1912.06851v1 [quant-ph]

“…Two such efforts are the ‘OnACIS’ [ 351 ] and ‘iSense’ [ 352 , 353 ] projects. Another effort is taking place at SYRTE [ 354 ]. A recent proposal is based on RF potentials and analyses the possibility of utilizing the atom chip for the creation of 3D traps which move on a loop in opposite directions [ 66 ].…”

Here we review the field of atom chips in the context of Bose–Einstein Condensates (BEC) as well as cold matter in general. Twenty years after the first realization of the BEC and 15 years after the realization of the atom chip, the latter has been found to enable extraordinary feats: from producing BECs at a rate of several per second, through the realization of matter-wave interferometry, and all the way to novel probing of surfaces and new forces. In addition, technological applications are also being intensively pursued. This review will describe these developments and more, including new ideas which have not yet been realized.
