Abstract

We present an optical aberration correction technique for ultracold quantum gas experiments which directly utilizes the quantum gas as a wave-front sensor. The direct use of the quantum gas enables correcting aberrations that are otherwise impractical to measure, e.g., introduced by vacuum windows. We report a root-mean-square precision and accuracy of $0.01\ensuremath{\lambda}$ and $0.03\ensuremath{\lambda}$, respectively, and also show independently the reduction of aberrations through measurement of the trap frequency of our optical tweezer. These improvements were achieved for a tweezer size that is well below our imaging resolution. The present work is in particular intended to serve as a tutorial for experimentalists interested in implementing similar methods in their experiment.

Aberration correction of optical dipole-traps array utilizing phase-modulated holographic technique

P Parkprom, N Chattrapiban, Nithiwadee Thaicharoen

Abstract Atom arrays generated by optical dipole traps are essential in quantum experiments, enabling precise manipulation and simulation of quantum states. They offer a competitive platform for quantum simulations due to their flexible configurations and local state addressability. However, preparing dipole-trap arrays within a vacuum chamber is challenged by the requirement for the laser beam to pass through multiple optical components which can induce deviations in the laser beam profile and cause aberrations in the system. To address this issue, we apply a holographic phase pattern to correct the aberration of an array of optical dipole traps according to these optical elements. We start with embedding the phase patterns into an SLM to generate the array of optical dipole traps. We then examine the aberrations induced by each optical element and develop methods for their correction. This is implemented by feeding back the modified phase pattern to restore the intended array pattern and eliminate aberrations using the modified Gerchberg–Saxton algorithm. This research enables the precise preparation of optical dipole trap arrays, which are crucial for future work in developing cold single-atom arrays prepared in a vacuum system.

Aberration compensation of optical tweezers for single-atom array

Jiayi Hou, Yu 玉 Jia 贾, Wen-Jun 文君 Xiao 夏 +5 more

Abstract High-precision preparation of holographic optical tweezers, which is a critical requirement for neutral atom quantum computing platforms, faces the challenge of system aberrations that degrade trap performance. In this paper, we propose a simple and efficient aberration correction algorithm for wavefront-sensorless optical systems, based on correcting the relative lateral shift of diffracted light across spatial regions. Applied to a cold atomic system, this technique demonstrates active correction of aberrations up to several wavelengths, reducing them to a peak-to-valley difference of 0.19(3) λ . The diffraction spot quality and optical trap depth are significantly improved after aberration correction. Combined with subsequent array optimization, the technique enables the generation of uniform optical trap arrays with enhanced atom-loading efficiency. The method requires no prior wavefront information or additional hardware, utilizing only an SLM and a standard CCD camera. Its computational efficiency and hardware simplicity make it broadly applicable to fields such as laser lithography and microscopy.

Self-Bayesian aberration removal via constraints for ultracold atom microscopy

Emine Altuntaş, Ian B. Spielman

High-resolution imaging of ultracold atoms typically requires custom high numerical aperture (NA) optics, as is the case for quantum gas microscopy. These high NA objectives involve many optical elements, each of which contributes to loss and light scattering, making them unsuitable for quantum backaction limited ``weak'' measurements. We employ a low-cost high NA aspheric lens as an objective for a practical and economical---although aberrated---high-resolution microscope to image $^{87}\mathrm{Rb}$ Bose-Einstein condensates. Here, we present a methodology for digitally eliminating the resulting aberrations that is applicable to a wide range of imaging strategies and requires no additional hardware. We recover nearly the full NA of our objective, thereby demonstrating a simple and powerful digital aberration correction method for achieving optimal microscopy of quantum objects. This reconstruction relies on a high-quality measure of our imaging system's even-order aberrations from density-density correlations measured with differing degrees of defocus. We demonstrate our aberration compensation technique using phase-contrast imaging, a dispersive imaging technique directly applicable to quantum backaction limited measurements. Furthermore, we show that our digital correction technique reduces the contribution of photon shot noise to density-density correlation measurements which would otherwise contaminate the desired quantum projection noise signal in weak measurements.

Observing the effect of wave-front aberrations in an atom interferometer by modulating the diameter of Raman beams

Min-Kang Zhou, Qin Luo, Lele Chen +2 more

The effect of wavefront aberrations is one of the most important systematic errors in atom interferometers and limits the accuracy of precision atom gravimeters. A detailed theoretical analysis of this effect is presented, and a theoretical method for observing this effect is proposed and demonstrated in experiment. In addition, with this method, the surface quality of the optical elements in the Raman system was measured with a rms resolution of $0.01\ensuremath{\lambda}$.

Feedback-enhanced algorithm for aberration correction of holographic atom traps

Graham D. Bruce, Matthew Y H Johnson, Edward Cormack +3 more

Abstract We show that a phase-only spatial light modulator can be used to generate non-trivial light distributions suitable for trapping ultracold atoms, when the hologram calculation is included within a simple and robust feedback loop that corrects for imperfect device response and optical aberrations. This correction reduces the discrepancy between target and experimental light distribution to the level of a few percent (root mean square error). We prove the generality of this algorithm by applying it to a variety of target light distributions of relevance for cold atomic physics.

Trapping, manipulating and probing ultracold atoms: a quantum technologies tutorial

L. Wolswijk, Luca Cavicchioli, G. Vinelli +12 more

Engineered ultracold atomic systems are a valuable platform for fundamental quantum mechanics studies and the development of quantum technologies. At near zero absolute temperature, atoms exhibit macroscopic phase coherence and collective quantum behavior, enabling their use in precision metrology, quantum simulation, and even information processing. This review provides an introductory overview of the key techniques used to trap, manipulate, and detect ultracold atoms, while highlighting the main applications of each method. We outline the principles of laser cooling, magnetic and optical trapping, and the most widely used techniques, including optical lattices and tweezers. Next, we discuss the manipulation methods of atomic internal and external degrees of freedom, and we present atom interferometry techniques and how to leverage and control interatomic interactions. Next, we review common ensemble detection strategies, including absorption and fluorescence imaging, state-selective readout, correlation and quantum non-demolition measurements and conclude with high-resolution approaches. This review aims to provide newcomers to the field with a broad understanding of the experimental toolkit that underpins research in ultracold atom physics and its applications across quantum science and technology.
