“…Under this condition, the simplified low-pass response becomes inadequate and a bandpass behaviour is observed, with an enhanced response to AC components at frequencies close to the pump-frequency detuning δ, as also observed in Ref. [40].…”

“…This paper aims to provide a more general analysis of the behaviour of a Bell-and-Bloom magnetometer when it operates in the presence of a generic time dependent field that is parallel to the static (bias) one. The availability of a more accurate model is of relevance when the output of a magnetometer is used as an error-signal to implement feedback based field-stabilization systems [36][37][38][39][40], as well as when designing feed-forward ones [41] or when evaluating the effects of strong stray fields. The later is of particular relevance for systems operated in unshielded environment [9,42].…”

The dynamic response of a Bell-and-Bloom magnetometer to a parallel (to the bias field) time-dependent field is modelled beyond the commonly assumed quasi-static regime. The results unveil features that are related to the parametric nature of the considered system. It is shown that a for low-amplitude time-dependent field different operating conditions are possible and that, beside the commonly reported low-pass-filter behaviour, a band-pass response emerges. Moreover, we numerically show that for larger field amplitude the system, due to its parametric nature, has a kind of ``non-linear'' response.

“…Tunable metasurfaces have found wide applications in fields such as communication, [221] imaging displays, [222] and holography. [223] The tunability of metasurfaces also presents significant opportunities for the development of quantum sensors, such as: 1) realizing real-time control of optical fields in a compact form, such as pump-probe switching and modulation, [224][225][226][227][228][229] providing new ideas and means for the practical and engineering realization of quantum sensors. 2) Changing the structure and properties of metasurfaces through stimuli such as electric fields, thermal fields, or optical fields.…”

Metasurface‐based optical field manipulation has significantly broadened the application range of micro‐optical components and integrated optics, gradually replacing bulky and complicated optical components. With the continuous development of micro and nano processing technology as well as computational analysis technology, metasurfaces have progressively shown their superior application prospects. After demonstrating tremendous results in classical optical applications, their application range has now extended to the field of quantum sensing. Due to their unique properties, such as small planar size, easy integration, flexible performance design, and tunable functionality, they have opened up a series of novel and rich applications for generating, manipulating, controlling, and detecting optical fields. In this paper, the basic principle and implementation of quantum measurement are presented and an overview of the design principles of metasurfaces, along with a summary of the latest advancements and potential applications of these surfaces in optical field modulation techniques for quantum precision measurement. Additionally, a thorough discussion and analysis of the challenges encountered by metasurfaces and their future development prospects is provided. Metasurfaces offer brand‐new opportunities for low‐cost, high‐performance, multifunctional miniaturized quantum sensors and are expected to play a significant role in the development of next‐generation quantum sensors.

“…The sensitivity of these devices strongly depends on the thermal spin noise of the ensemble [24], with a lower limit set by purely quantum constraints on the minimum spin projection noise [25][26][27]. On the other hand, the impact of magnetic noise on OPM measurement has been pointed [28,29], and a magnetic noise stabilization scheme based on dual-species cells have been recently proposed [30]. However, the link between the spin noise in the ensemble and the magnetic noise itself is yet to be clarified.…”

We theoretically and numerically investigate the spin fluctuations induced in athermal atomic ensemble by an external fluctuating uniaxial magnetic field, in thecontext of a standard spin noise spectroscopy (SNS) experiment. We show thatadditional spin noise is excited, which dramatically depends on the magnetic noisevariance and bandwidth, as well as on the power of the probe light and its polarizationdirection. We develop an analytical perturbative model proving that this spin noise firstemerges from the residual optical pumping in the medium, which is then converted intospin fluctuations by the magnetic noise and eventually detected using SNS. The systemstudied is a spin-1 system, which thus shows both Faraday rotation and ellipticity noisesinduced by the random magnetic fluctuations. The analytical model gives resultsin perfect agreement with the numerical simulations, with potential applications infuture experimental characterization of stray field properties and their influence onspin dynamics.
