“…A promising technology for the creation of a practical gravitational eye is to use cold-atom gravimetry based on atom interferometry [21]. Cold atoms-based systems have shown themselves to be sensitive metrological tools in fundamental research [38][39][40], which has prompted research to evaluate the opportunities offered by the technology [41][42][43][44][45] and to develop portable cold atom sensors to address a number of real-world applications [46][47][48][49][50][51][52][53][54][55][56][57][58][59][60].…”

Gravity measurements have uses in a wide range of fields including geological mapping and mine-shaft inspection. The specific application in question sets limits on the survey and the amount of information that can be obtained. For example, in a conventional gravity survey at the Earth’s surface a gravimeter is translated on a two-dimensional planar grid taking measurements of vertical component of gravity. If, however, the survey points cannot be chosen so freely, for example if the gravimeter is constrained to operate in a tunnel where only a one-dimensional line of data could be taken, less information will be obtained. To address this situation, we investigate an alternative approach, in the form of an instrument which rotates around a central point measuring the gravitational potential on the boundary of a sphere around the centre of the instrument. The ability to record additional components of gravity by rotating the gravimeter will give more information than obtained with a single measurement traditionally taken at each point on a survey, consequently reducing ambiguities in interpretation. We term a device which measures the potential, or its radial derivatives, around the surface of a sphere a gravitational eye. In this article we explore ideas of resolution and propose a thought experiment for comparing the performance of diverse types of gravitational eye. We also discuss radial analytic continuation towards sources of gravity and the resulting resolution enhancement, before finally discussing the possibility of using cold-atom gravimetry and gradiometry to construct a gravitational eye. If realised, the gravitational eye will offer revolutionary capability enabling the maximum information to be obtained about features in all directions around it.

“…We began by identifying the most relevant databases. The "quantum sensing" search query, which was confined to scholarly peerreviewed papers published between 2018 and 2022, lead us to focus on the following databases: ProQuest (847 publications), EBSCO (315), Springer (280), IEEEXplore (121), Scopus (94), and Web of Science (85) results accordingly. We built and tested the detailed search criteria based on the research questions until the final search query was defined.…”

“…On the other hand, setups for analyzing a single ion can be relatively simple and require less complex technology to achieve the same degree of precision as their counterparts that study neutral atoms, but at the expense of longer averaging times. Some representative publications utilizing these technologies are works of [29,30,31].…”

The current rise of quantum technology is compelled by quantum sensing research. Thousands of research labs are developing and testing a broad range of sensor prototypes. However, there is a lack of knowledge about specific applications and real-world use cases where the benefits of these sensors will be most pronounced. This study presents a comprehensive review of quantum sensing state-of-practice. It also provides a detailed analysis of how quantum sensing overcomes the existing limitations of sensordriven systems' precision and performance. Based on the review of over 500 quantum sensor prototype reports, we determined four groups of quantum sensors and discussed their readiness for commercial usage. We concluded that quantum magnetometry and quantum optics are the most advanced sensing technologies with empirically proven results. In turn, quantum timing and kinetics are still in the early stages of practical validation. In addition, we defined four systems domains in which quantum sensors offer a solution for existing limitations of conventional sensing technologies. These domains are 1) GPS-free positioning and navigating services, 2) time-based operations, 3) topological visibility, and 4) environment detection, prediction, and modeling. Finally, we discussed the current constraints of quantum sensing technologies and offered directions for future research.

“…8 In recent years, significant efforts have been made to drive cold-atom experiments out of the laboratory and into compact apparatus where they can meet the demand of real-world applications. [9][10][11][12][13] Parallel to bringing cold-atom sensors into a portable apparatus, many research ventures have now focused on the development of chip-scale components to enable a scalability that is more competitive with thermal packages. Notable examples include micro-fabricated optics, 14 ion-pumps, 15 diffractive elements, 16 planar coils, 17,18 micro-electromechanical-systems (MEMS) ultra-high-vacuum (UHV) cells, 19,20 photonically integrated circuits and microfabricated alkali regulators.…”

Using a simple and cost-effective water-jet process, we have overcome silicon etch depth limitations to realize a 6 mm deep atomic vapor cell. We have successfully used this approach to demonstrate a two-chamber geometry by including a 25 mm meandering channel between the alkali pill chamber and main interrogation chamber. Additionally, we have recently used this approach in the fabrication of deep cut silicon cells for cold atom systems. The results will be highlighted, as well as providing an overview of our advancements on mass producible components for cold-atom systems and the amalgamation of this technology towards a fully integrated system.
