“…In addition, it would be desirable to extend quantum gas microscopy techniques beyond two dimensions, thus enabling the control and study of multilayered systems. This is highly challenging, because the high density of the analyzed systems, on scales of the optical resolution, prevents the employment of multilayer readout schemes that are suitable for systems with large lattice spacing and vanishing tunnel coupling between sites [25][26][27]. For bosons, a first example of such a scheme has been demonstrated [28].…”

Robust Bilayer Charge Pumping for Spin- and Density-Resolved Quantum Gas Microscopy

Quantum gas microscopy has emerged as a powerful new way to probe quantum many-body systems at the microscopic level. However, layered or efficient spin-resolved readout methods have remained scarce as they impose strong demands on the specific atomic species and constrain the simulated lattice geometry and size. Here we present a novel high-fidelity bilayer readout, which can be used for full spin-and densityresolved quantum gas microscopy of two-dimensional systems with arbitrary geometry. Our technique makes use of an initial Stern-Gerlach splitting into adjacent layers of a highly stable vertical superlattice and subsequent charge pumping to separate the layers by 21 μm. This separation enables independent highresolution images of each layer. We benchmark our method by spin-and density-resolving twodimensional Fermi-Hubbard systems. Our technique furthermore enables the access to advanced entropy engineering schemes, spectroscopic methods, or the realization of tunable bilayer systems.

“…Transportable optical atomic clocks will still be a valuable directions [200] as this kind of clock has been demonstrated for geodesy application [201]. Additionally, miniature setups also find their special applications in certain fields, and efforts on developing of smaller magnetometers and interferometers would never be overemphasized [90,172].…”

“…This is the first demonstration that laser cooled atoms could be used to improve the performance of magnetic field measurement. Since then, atomic magnetometers using non-degenerate cooled gases have been realized in different traps and a sensitivity down to 10 pT/ √ Hz and a spatial resolution to 50 µm were reported [85][86][87][88][89][90].…”

Recent progresses on quantum control of cold atoms and trapped ions in both the scientific and technological aspects greatly advance the applications in precision measurement. Thanks to the exceptional controllability and versatility of these massive quantum systems, unprecedented sensitivity has been achieved in clocks, magnetometers and interferometers based on cold atoms and ions. Besides, these systems also feature many characteristics that can be employed to facilitate the applications in different scenarios. In this review, we briefly introduce the principles of optical clocks, cold atom magnetometers and atom interferometers used for precision measurement of time, magnetic field, and inertial forces. The main content is then devoted to summarize some recent experimental and theoretical progresses in these three applications, with special attention being paid to the new designs and possibilities towards better performance. The purpose of this review is by no means to give a complete overview of all important works in this fast developing field, but to draw a rough sketch about the frontiers and show the fascinating future lying ahead.

Remote control of experimental systems allows for improved collaboration between research groups as well as unique remote educational opportunities accessible by students and citizen scientists. Here, we describe an experiment for the production and investigation of ultracold quantum gases capable of asynchronous remote control by multiple remote users. This is enabled by a queuing system coupled to an interface that can be modified to suit the user, e.g. a gamified interface for use by the general public or a scripted interface for an expert. To demonstrate this, the laboratory was opened to remote experts and the general public. During the available time, remote users were given the task of optimising the production of a Bose-Einstein condensate (BEC). This work thus provides a stepping stone towards the exploration and realisation of more advanced physical models by remote experts, students and citizen scientists alike.
