Here, we present an on-chip spectrometer that leverages an integrated thin-film lithium niobate modulator to produce a frequency-agile electro-optic frequency comb for interrogating chip-scale temperature and acceleration sensors. The chirped comb process allows for ultralow radiofrequency drive voltages, which are as much as seven orders of magnitude less than the lowest found in the literature and are generated using a chip-scale, microcontroller-driven direct digital synthesizer. The on-chip comb spectrometer is able to simultaneously interrogate both an on-chip temperature sensor and an off-chip, microfabricated optomechanical accelerometer with cutting-edge sensitivities of <span><span style=\"color: inherit;\"><span><span style=\"margin-left: 0.333em; margin-right: 0.333em;\">≈</span><span style=\"margin-left: -0.167em; width: 0em; height: 0em;\"></span><span><span>5</span></span><span style=\"width: 0.278em; height: 0em;\"></span><span>µ</span><span><span>K</span></span><span style=\"margin-left: 0.267em; margin-right: 0.267em;\">⋅</span><span><span><span style=\"margin-right: 0.05em;\"><span>H</span><span>z</span></span><span style=\"vertical-align: 0.5em;\"><span>−</span><span>1</span><span><span>/</span></span><span>2</span></span></span></span></span></span><script type=\"math/tex\">approx !{5};unicode{x00B5} {rm K} cdot {{rm Hz}^{- 1/2}}</script></span> and <span><span style=\"color: inherit;\"><span><span style=\"margin-left: 0.333em; margin-right: 0.333em;\">≈</span><span style=\"margin-left: -0.167em; width: 0em; height: 0em;\"></span><span><span>130</span></span><span style=\"width: 0.278em; height: 0em;\"></span><span>µ</span><span><span>m</span></span><span style=\"margin-left: 0.267em; margin-right: 0.267em;\">⋅</span><span><span><span style=\"margin-right: 0.05em;\"><span>s</span></span><span style=\"vertical-align: 0.5em;\"><span>−</span><span>2</span></span></span></span><span style=\"margin-left: 0.267em; margin-right: 0.267em;\">⋅</span><span><span><span style=\"margin-right: 0.05em;\"><span>H</span><span>z</span></span><span style=\"vertical-align: 0.5em;\"><span>−</span><span>1</span><span><span>/</span></span><span>2</span></span></span></span></span></span><script type=\"math/tex\">approx !{130};unicode{x00B5}{rm m} cdot {{rm s}^{- 2}} cdot {{rm Hz}^{- 1/2}}</script></span>, respectively.

A standard approach consists of measuring these aberrations with a wavefront sensor (e.g., Shack–Hartmann) located in the pupil plane, and compensating for them either digitally or by adaptive optics with a wavefront shaper. However, in its usual implementation this strategy can only extract aberrations within a single isoplanatic patch, i.e., a region where the aberrations remain correlated. This limitation severely reduces the effective field-of-view in which the correction can be performed. Here, we propose a wavefront sensing method capable of measuring, in a single shot, various pupil aberrations corresponding to multiple isoplanatic patches. The method, based on a thin diffuser (i.e., a random phase mask), exploits the dissimilarity between different speckle regions to multiplex several wavefronts incoming from various incidence angles. We present proof-of-concept experiments carried out in widefield fluorescence microscopy. A digital deconvolution procedure in each isoplanatic patch yields accurate aberration correction within an extended field-of-view.

Already with two separate arrays, we implement combined 2D configurations of 3000 qubit sites with a mean number of 1167(46) single-atom quantum systems. The transfer of atoms between the two arrays is achieved with high efficiency. Thus, supercharging one array designated as the quantum processing unit with atoms from the secondary array significantly increases the number of qubits and the initial filling fraction.
