Rev. Applied 19, 044051 (2023) – Published 18 April 2023 Synopsis:Sensing Electric Fields in Ion Sources Cold-atom-based ion sources (CABIS) are a timely example of how laser cooling and trapping can be used in practical applications, such as nanofabrication and microscopy. Unfortunately, Coulomb repulsion between ions can significantly deteriorate CABIS performance. The authors demonstrate that embedded Rydberg atoms can be used for noninvasive, near-real-time measurement of the electric fields between ions in CABIS, and thereby to control Coulomb-induced degradation via feedback. The spectra of different Rydberg states reveal which states are suitable for low- and high-field monitoring, and this work also sheds light on many-body interactions between ultracold ions and neutral atoms.     Featured in Physics Porous-Solid Metaconverters for Broadband Underwater Sound Absorption and Insulation Hao-Wen Dong, Sheng-Dong Zhao, Ping Xiang, Bing Wang, Chuanzeng Zhang, Li Cheng, Yue-Sheng Wang, and Daining Fang Phys. Rev. Applied 19, 044074 (2023) – Published 25 April 2023 Synopsis:Metamaterial Provides Underwater Stealth A lightweight structure made of rubber and metal layers can provide an object with underwater acoustic stealth over a broad frequency range.     Editors' Suggestion Chip-Scale Packages for a Tunable Wavelength Reference and Laser Cooling Platform S. Dyer, K. Gallacher, U. Hawley, A. Bregazzi, P.F. Griffin, A.S. Arnold, D.J. Paul, E. Riis, and J.P. McGilligan Phys. Rev. Applied 19, 044015 (2023) – Published 5 April 2023 The miniaturization of cold-atom systems brings high accuracy into portable atomic metrology. However, the impact of cold-atom sensors in real-world applications has been limited by the overall laser cooling package. This study amalgamates a chip-scale optics setup with a microfabricated laser cooling system to dramatically reduce device size, weight, and power usage. The authors use an on-chip Zeeman offset lock for laser cooling, and demonstrate improved atom number afforded by new techniques in silicon cell fabrication. The simplicity, scalability, and utility demonstrated in this cold-atom platform will enable exciting opportunities in portable cold-atom clocks and interferometers.     Editors' Suggestion Intrinsic and Extrinsic Factors Influencing the Dynamics of VO2 Mott Oscillators Stephanie M. Bohaichuk, Suhas Kumar, Mahnaz Islam, Miguel Muñoz Rojo, R. Stanley Williams, Gregory Pitner, Jaewoo Jeong, Mahesh G. Samant, Stuart S.P. Parkin, and Eric Pop Phys. Rev. Applied 19, 044028 (2023) – Published 10 April 2023 Many biomimetic computing schemes rely on neuronlike spiking devices, but to design practical systems a deeper understanding of device dynamics is still needed. This study identifies major influences on oscillatory time scales of Mott-insulator-based nanoscale devices with carbon nanotube electrodes. In particular, the authors find that current sources and measurement instruments participate in the observed dynamics. The results highlight paths to control spiking behavior, using not only device thermodynamics and size, but also external circuitry.     Editors' Suggestion All-Optical Magnetothermoelastic Skyrmion Motion Serban Lepadatu Phys. Rev. Applied 19, 044036 (2023) – Published 12 April 2023 The author's calculations show that magnetic skyrmions in metallic multilayers such as Co/Pt can be controllably moved on surfaces, simply by using a focused laser beam. Temperature gradients at the laser spot directly yield skyrmion motion, due to temperature dependence of magnetic parameters, but another contribution can be even more important: Thermoelastic lattice expansion results in a strain-induced local gradient in magnetic anisotropy. This method of skyrmion displacement allows full control of motion over a magnetic surface, with a possible path to MEMS-VCSEL on-chip integration.     Editors' Suggestion Ferrimagnetic Oscillator Magnetometer John F. Barry, Reed A. Irion, Matthew H. Steinecker, Daniel K. Freeman, Jessica J. Kedziora, Reginald G. Wilcox, and Danielle A. Braje Phys. Rev. Applied 19, 044044 (2023) – Published 17 April 2023 Quantum sensors based on solid-state spins have advanced rapidly over the prior decade, but deploying these sensors in real-world applications remains technically challenging. By introducing an innovative oscillator-based sensor architecture, and employing a ferrimagnetic material rather than the paramagnetic spin defects more commonly studied, this work details the construction of a compact magnetometer with a minimum sensitivity of 100 fT/√Hz. The sensor's architecture offers advantages in dynamic range, simplicity, and compactness—qualities that may enable widespread use of solid-state quantum sensors outside a laboratory environment.     Editors' Suggestion Programmable Spatiotemporal Quantum Parametric Mode Sorter Malvika Garikapati, Santosh Kumar, He Zhang, Yong Meng Sua, and Yu-Ping Huang Phys. Rev. Applied 19, 044070 (2023) – Published 24 April 2023 Photons are ideal information carriers for sensing, communication, and computing. In principle, a single photon can carry much information in its spatiotemporal modes; the challenge is to read it out, as linear optical elements are not sensitive to the subtle differences among those modes. This study demonstrates a nonlinear-optical approach in which a single pass through a LiNiO3 waveguide can separate photons according to their detailed spatiotemporal profiles or their superpositions, even if they completely overlap with each other. This provides access to photons' large Hilbert spaces, pointing to applications in free-space quantum communication, computing, and sensing.     Editors' Suggestion Nonlinear Response and Crosstalk of Electrically Driven Silicon Spin Qubits Brennan Undseth, Xiao Xue, Mohammad Mehmandoost, Maximilian Rimbach-Russ, Pieter T. Eendebak, Nodar Samkharadze, Amir Sammak, Viatcheslav V. Dobrovitski, Giordano Scappucci, and Lieven M.K. Vandersypen Phys. Rev. Applied 19, 044078 (2023) – Published 25 April 2023 Frequency multiplexing of operations is an attractive strategy to control multiple qubits simultaneously in a spin-based quantum processor with relatively few control lines. However, high-fidelity operation demands good spectral addressability and noncontextual spin dynamics. The authors explore an unexpected crosstalk mechanism, in which the Rabi frequency of one spin changes markedly depending on the simultaneous operation of another. They also connect this behavior to another surprising feature: the nonlinear scaling of Rabi frequency with resonant driving amplitude. These results provide insight into the challenges that such state-of-the-art control methods will face.     Editors' Suggestion Impedance-Matched Differential Superconducting Nanowire Detectors Marco Colangelo et al. Phys. Rev. Applied 19, 044093 (2023) – Published 28 April 2023 Superconducting nanowire single-photon detectors (SNSPDs) are the highest-performance photon-counting technology in the near infrared, but traditional designs typically trade off between timing resolution and detection efficiency. The authors utilize transmission-line engineering and differential readout to achieve a design with high detection efficiency and low jitter simultaneously. This design also enables imaging capabilities and photon-number resolution, and is compatible with commercial time taggers. The device is a versatile solution for photon counting in various applications, including quantum computing, quantum communication, biomedicine, and ranging.     Editors' Suggestion Letter Sound Waveguiding by Spinning: An Avenue toward Unidirectional Acoustic Spinning Fibers Mohamed Farhat, Pai-Yen Chen, and Ying Wu Phys. Rev. Applied 19, L041002 (2023) – Published 26 April 2023 Although optical fiber has revolutionized modern life, creating a corresponding fiber as a waveguide for airborne sound has proven difficult, due to the scarcity of high-index acoustic materials. In this study the authors utilize spinning of the air inside a metamaterial tube to create an acoustic fiber. Their simulations demonstrate nonreciprocal propagation resulting from the acoustic equivalent of the Zeeman effect, which leads to robust waveguiding in the proposed fiber. This contribution may open avenues for studying the physics of acoustic vortex beams and nonreciprocal phenomena.     LETTERS Letter Charge Dynamics in Spintronic Terahertz Emitters Georg Schmidt, Bikash Das-Mohapatra, and Evangelos Th. Papaioannou Phys. Rev. Applied 19, L041001 (2023) – Published 12 April 2023 An important issue for spintronic terahertz emitters is the analysis of spin-current generation and spin-to-charge conversion based on the emitted terahertz signal. This study shows that for such analysis it is mandatory to understand and account for local charging phenomena, which occur due to the limited area in which ultrafast currents are generated. Charge backflow strongly modifies the ensuing charge-current profile. This result is crucial for correctly interpreting the profile of the emitted terahertz pulse.     Editors' Suggestion Letter Sound Waveguiding by Spinning: An Avenue toward Unidirectional Acoustic Spinning Fibers Mohamed Farhat, Pai-Yen Chen, and Ying Wu Phys.

Rev. Applied 19, L041003 (2023) – Published 27 April 2023 Indistinguishable single photons are a key requirement for most applications in optical quantum information. However, this feature has remained elusive among two-dimensional materials, primarily due to insufficient coherence of emitters. Here the authors controllably generate a spectrally narrow and stable single-photon source in an h-BN crystal by electron-beam irradiation, and demonstrate Hong-Ou-Mandel interference of the emitted photons, which is a signature of indistinguishability. These results enable practical applications in integrated quantum photonics based on two-dimensional materials.     ARTICLES Controlled-Controlled-Phase Gates for Superconducting Qubits Mediated by a Shared Tunable Coupler Niklas J.

Rev. Applied 19, 044051 (2023) – Published 18 April 2023 Synopsis:Sensing Electric Fields in Ion Sources Cold-atom-based ion sources (CABIS) are a timely example of how laser cooling and trapping can be used in practical applications, such as nanofabrication and microscopy. Unfortunately, Coulomb repulsion between ions can significantly deteriorate CABIS performance. The authors demonstrate that embedded Rydberg atoms can be used for noninvasive, near-real-time measurement of the electric fields between ions in CABIS, and thereby to control Coulomb-induced degradation via feedback. The spectra of different Rydberg states reveal which states are suitable for low- and high-field monitoring, and this work also sheds light on many-body interactions between ultracold ions and neutral atoms.     Strain-Induced Medium-Temperature Thermoelectric Performance of Cu4TiSe4: The Role of Four-Phonon Scattering Xue-Kun Chen, En-Ming Zhang, Dan Wu, and Ke-Qiu Chen Phys.

Rev. Applied 19, 044070 (2023) – Published 24 April 2023 Photons are ideal information carriers for sensing, communication, and computing. In principle, a single photon can carry much information in its spatiotemporal modes; the challenge is to read it out, as linear optical elements are not sensitive to the subtle differences among those modes. This study demonstrates a nonlinear-optical approach in which a single pass through a LiNiO3 waveguide can separate photons according to their detailed spatiotemporal profiles or their superpositions, even if they completely overlap with each other. This provides access to photons' large Hilbert spaces, pointing to applications in free-space quantum communication, computing, and sensing.     Nontrivial Topological Features and Griffith's-Phase Behavior in CrFeVGa Probed by Experiment and Theory Jadupati Nag, P.C.

Applied 19, 044078 (2023) – Published 25 April 2023 Frequency multiplexing of operations is an attractive strategy to control multiple qubits simultaneously in a spin-based quantum processor with relatively few control lines. However, high-fidelity operation demands good spectral addressability and noncontextual spin dynamics. The authors explore an unexpected crosstalk mechanism, in which the Rabi frequency of one spin changes markedly depending on the simultaneous operation of another. They also connect this behavior to another surprising feature: the nonlinear scaling of Rabi frequency with resonant driving amplitude. These results provide insight into the challenges that such state-of-the-art control methods will face.     High-Sensitivity Rydberg-Atom-Based Phase-Modulation Receiver for Frequency-Division-Multiplexing Communication Yafen Cai, Shuai Shi, Yijia Zhou, Yitong Li, Jianhao Yu, Weibin Li, and Lin Li Phys.

The authors utilize transmission-line engineering and differential readout to achieve a design with high detection efficiency and low jitter simultaneously. This design also enables imaging capabilities and photon-number resolution, and is compatible with commercial time taggers. The device is a versatile solution for photon counting in various applications, including quantum computing, quantum communication, biomedicine, and ranging.     Designing Globally Time-Optimal Entangling Gates Using Geometric Space Curves Ho Lun Tang, Kyle Connelly, Ada Warren, Fei Zhuang, Sophia E.
