Cavity quantum electrodynamics (cQED) harnesses light-matter interactions to produce nonclassical light states. However, a fundamental challenge lies in simultaneously achieving Purcell enhancement and tailored wavefront control within a single cavity, due to conflicting resonator requirements. Here, we overcome this limitation by demonstrating triggered single-photon emission with customizable wavefronts from semiconductor quantum dots embedded in geometric-phase metacavities. These monolithic devices - only 200 nm thick - deliver Purcell-enhanced emission alongside spin-momentum-locked radiation, vortex beams, and holographic patterns. The meta-atom lattice provides high-Q optical confinement, while spatially modulated orientations enable efficient outcoupling of photons with designed states. This work establishes a new paradigm for intrinsically multiplexing metasurface-based wavefront shaping with cQED, enabling high-performance quantum light sources from subwavelength-scale monolithic platforms.

Reconfigurable interfaces between confined optical modes in integrated photonic chips and structured light in free space would benefit fundamental optical science and photonic technologies. Here we exploit the anisotropic nonlinear susceptibility tensors associated with thin-film lithium niobate to construct nanophotonic chip-space interfaces capable of generating and multidimensionally engineering structured light via injections of photons to on-chip waveguides. Harnessing the nonlinear Čerenkov radiation in integrated nonlinear microring resonators, we tailor the spatial profile, polarization state, emission wavelength, topological charge and temporal wave packet of structured optical vortices, exhibiting reconfigurability and tunability. To showcase the capabilities of our platform, we use continuous-wave excitation to generate tunable optical skyrmions via the spin-orbit coupling and multistate integrated vortex microcombs in the short near-infrared range via synergistic χ(2) and χ(3) nonlinear optical processes. Our work bridges the research fields of structured light and integrated nonlinear optics, providing opportunities for spatiotemporal light generation and on-chip multidimensional nonlinear optics.

High-fidelity focused spots, achieving the diffraction limit and ultra-low crosstalk, are critical for manipulating trapped atoms and ions. Despite the existence of various aberration compensation techniques, obtaining such high-quality focused spots remains challenging for far-detuned laser systems. Here, we demonstrate a universal in-situ aberration correction technique for far-detuned-laser-based individual addressing systems. Our approach utilizes a trapped ion as a probe and a spatial light modulator for optical aberration compensation, demonstrating 17-fold suppression of crosstalk and achieving a low Rabi crosstalk of 0.031(4)%, nearly a four-fold improvement over previous state-of-the-art results. This method establishes an effective tool for high-fidelity quantum operations in trapped ion and atom systems, pivotal for quantum computing.

Abstract A promising pathway towards scalable quantum photonic processors involves the simultaneous integration of deterministic single-photon sources, low-loss photonic circuitry, and fast reconfigurability. Thin-film lithium tantalate on insulator (LTOI) offers an exceptional electro-optic response and low optical loss at 900 nm wavelength band, yet its lack of efficient quantum emitters has hindered progress toward fully integrated quantum technologies. Here, we demonstrate heterogeneous integration of indium arsenide quantum dots (QDs) with low-loss reconfigurable LTOI waveguides (0.30 ± 0.04 dB/cm) using micro-transfer printing. By directly butt-coupling tapered gallium arsenide waveguides with inversely tapered LTOI waveguides, we achieve robust and alignment-tolerant inter-waveguide coupling. The hybrid chip operates at cryogenic temperatures, enabling deterministic routing of successively emitted single photons from the QDs with a half-wave voltage-length product ( ~ 1.9 V·cm at 4 K), confirming the cryogenic stability of LTOI’s electro-optic coefficient. These results establish demonstration of high-speed on-chip routing of single photons with hybrid QD-LTOI circuits, providing a scalable pathway toward integrated quantum photonic processors.

Miniaturized and reconfigurable interfaces between confined optical modes within integrated photonic chips and structured light propagating in free space would serve as a cornerstone for fundamental optical science and modern photonic technology. In this work, we exploit the anisotropic nonlinear susceptibility tensors associated with thin-film lithium niobate to construct nanophotonic chip-space interfaces capable of flexibly generating and multi-dimensionally engineering structured light via injections of photons to on-chip waveguides. By harnessing the nonlinear Čerenkov radiation in integrated nonlinear microring resonators, we successfully tailor the spatial profile, polarization state, emission wavelength, topological charge and temporal wave packet of structured optical vortices, exhibiting reconfigurabilities and tuning ranges far beyond the state-of-the-art. To further showcase the capabilities of our platform, we use a single pump to generate tunable optical skyrmions via the spin-orbit coupling and multi-state integrated vortex microcombs in the visible range via synergistic χ^(2) and χ^(3) nonlinear optical processes. Our work bridges the research fields of structured light and integrated nonlinear optics, providing unprecedented opportunities for spatiotemporal light generation and on-chip multidimensional nonlinear optics.

We demonstrate a fully integrable and reconfigurable platform for controlling quantum emission by harnessing chiral exceptional bound states in the continuum (BICs) as a higher-order non-Hermitian singularity. Our architecture employs dual-microring resonators evanescently coupled to two waveguides, supporting symmetry-protected BICs. By integrating a waveguide-coupled reflector coupled with one resonator as a unidirectional feedback, a pair of orthogonal BICs gets transformed into a single, chiral quasi-BIC residing on an exceptional surface. The phase terms in external coupling and inter-modal coupling serve as two independent tuning knobs, enabling unprecedented dynamic control over the spontaneous emission dynamics of individual quantum emitters, including the Purcell enhancement and the emission lineshape. The efficiency in reconfiguring the output intensity gets promoted by more than a factor of two compared to alternative schemes, offering a promising path toward high-speed quantum optical switches and active lifetime control in integrated quantum photonic circuits.

Exceptional points (EPs) promise revolutionary control over quantum light-matter interactions. Here, we experimentally demonstrate flexible and reversible engineering of quantum vacuum fluctuation in an integrated microcavity supporting chiral Eps. We develop a hybrid lithium niobate (LN)-GaAs quantum photonic platform, seamlessly combining high-quality quantum emitters, a low-loss photonic circuit, efficient electro-optic (EO) effect, and local strain actuator in a single device. Chiral EPs are implemented by dynamically tuning the coupling between the modes associated with a micro-ring resonator, resulting in anomalous spontaneous emission dynamic with a 7-fold modulation of the lifetime (120 ps to 850 ps). Meanwhile, we reshape single-photon spectra via cavity local density of states (LDOS) engineering and generate non-Lorentzian spectral profiles: squared-Lorentzian, Fano-like, and EP-induced transparency (EPIT), a suppression of emission at zero detuning. This work unveils exotic cavity quantum electrodynamics (cQED) effects unique to EPs and establishes a universal paradigm for non-Hermitian quantum photonics.

The construction of entangling gates with individual addressing capability represents a crucial approach for implementing quantum computation in trapped-ion crystals. Conventional entangling gate schemes typically rely on laser beam wave vectors to couple the ions' spin and motional degrees of freedom. Here, we experimentally demonstrate an alternative method that employs a polarization gradient field generated by a tightly focused laser beam-an approach theoretically proposed as the Magnus effect for quantum logic gate design [Mazzanti et al., Phys. Rev. Res. 5, 033036 (2023)PPRHAI2643-156410.1103/PhysRevResearch.5.033036]. Using this technique, we perform Raman operations on hyperfine qubits encoded in ^{171}Yb^{+} ions, generating spin-dependent forces along axial motional modes in a linear trap. By utilizing an acousto-optic deflector to create arbitrary spot pairs for individual ion addressing in two-ion (four-ion) chains, we achieve Mølmer-Sørensen gates with Bell-state fidelities exceeding 98.7(1)% [and 97.2(4)%]. Further improvements in numerical aperture (NA) and laser power could reduce gate durations while enhancing fidelity by orders of magnitude. This method is compatible with-and can significantly simplify-optical tweezer gate proposals, where motional mode engineering enables scalable trapped-ion quantum computation. The technique can be readily extended to two-dimensional ion crystals, representing a key advancement toward large-scale trapped-ion quantum processors.

The development of high-performance chip-scale ion traps is crucial for the integration and scaling of ion-trap-based quantum computers. Although cryogenic environments can greatly reduce anomalous heating, operating ion traps at room temperature remains highly attractive due to its simplicity and lower cost. This work reports significant progress in coherently controlling multiple ions confined in a custom-fabricated, room-temperature surface-electrode trap, establishing a critical foundation for advanced quantum protocols such as quantum error correction and future scalable architectures. Research objectives and methods This study aims to characterize a home-built chip trap and demonstrate its capabilities for multi-ion quantum logic under ambient conditions. The trap adopts a six-wire electrode design on a high-resistivity silicon substrate, with ions trapped at a height of 154 mu m. A combination of Doppler cooling, electromagnetically induced transparency (EIT) cooling, and resolved-sideband cooling is used to prepare the ions in their motional ground state. Coherent manipulations are performed using both a 729 nm laser (for optical qubits between the |S-1/2, m(j) = -1/2 > and |D-5/2, m(j )= -3/2 > states) and microwave radiation (for qubits between the |S-1/2, m(j) = -1/2 > and |S-1/2, m(j) = +1/2 > states). Quantum state detection is achieved via state-dependent fluorescence by using an EMCCD camera, thereby enabling site-resolved readout. Key results Low room-temperature heating rates: The trap exhibits low heating rates, measured to be 0.074(8) quanta/ms in the axial direction (at 833 kHz) and 0.237(51) quanta/ms in the radial direction (at 1.3 MHz). The spectral density of electric-field noise is on the order of 10(-13) V-2/(m(2) Hz) at trap frequencies above 500 kHz, ranking among the best for room-temperature devices. The spectral density of electric-field noise follows an approximate f(-2.52(22)) dependence, potentially influenced by external filtering circuits. High-fidelity single-ion control: A single 40Ca+ ion is cooled to an average phonon number of 0.04(2) in its axial motion. High-fidelity coherent operations are demonstrated: carrier Rabi oscillations using the 729 nm laser shows a single-pulse fidelity of approximately 98.98(8)%, while microwave-driven operations achieves a fidelity of 99.95(2)%. Ramsey interferometry with microwaves reveals a coherence time T2* of 5.0(4) ms. Site-resolved multi-ion coherent control: The core achievement is the global coherent manipulation of ion chains containing up to 20 ions. The system is characterized by driving motional sideband transitions on various axial modes of 5-and 6-ion chains. The resulting Rabi oscillations, measured using site-resolved fluorescence, clearly show the collective dynamics and mode-dependent coupling strengths determined by the normalized mode eigenvectors. Furthermore, global carrier transitions are demonstrated on a two-dimensional (2D) zigzag crystal of 20 ions, confirming the ability to execute simultaneous operations on a large qubit array. Global control of 2D ion crystals: Using 20 ions, a 2D zigzag crystal is formed and globally addressed using both laser and microwave drives. Laser-driven carrier transitions show strong decay due to multimode motional coupling, whereas microwave-driven oscillations remain nearly decay-free, consistent with the Lamb-Dicke parameter being negligible for microwave fields. Conclusion The room-temperature surface-electrode trap can support low-heating confinement, highfidelity single-and multi-qubit operations, as well as coherent control of large ion arrays. The site-resolved observations of mode-dependent coupling highlight the potential for utilizing collective vibrational modes for selective quantum control. These results validate the trap as a robust and promising platform for medium-scale quantum information processing and quantum simulation at room temperature. Future work will focus on structural optimizations to reduce radial heating and integration with cryogenic systems to further suppress noise, ultimately advancing toward large-scale quantum computing architectures.

In experiments with atomic qubits encoded in the hyperfine levels of cold atoms or ions, the generation and control of multiple laser frequencies are often required for laser cooling and qubit manipulation. In this work, we demonstrate a laser system that integrates laser cooling, qubit initialization and detection, and Raman operations into a single setup, utilizing fiber laser technology and nonlinear optics. Specifically, a 369 nm laser for preparing and detecting Yb-171(+) ions, and a 554 nm laser for qubit Raman manipulation, are generated by modulating a seed laser at 1108 nm through a fiber electro-optic modulator (EOM), amplified by a Yb-doped fiber amplifier, and then converted to 369 nm and 554 nm using two sequentially placed periodically-poled nonlinear crystals. This method offers significant flexibility and scalability, as different laser frequencies can be generated by adding specific radio-frequency signals to the electronic system, without altering the optical setup. The switching time between laser frequency channels is measured at 6.5 ns. With a modulation bandwidth of 20 GHz, this approach can accommodate the hyperfine splittings of various ion species. Overall, This scheme optimizes the optical configuration for atom and ion operations, minimizes insertion losses, and provides an efficient multi-channel laser frequency generation solution, making it highly beneficial for atomic and ionic quantum information experiments.

Significance Ion trap quantum computing, distinguished by its significant advantages such as long coherence times and high-fidelity quantum gate operations, has emerged as a leading frontier in quantum technology. The core challenge in realizing practical quantum computing lies in the scalable expansion of the system. The quantum charge-coupled device (QCCD) architecture, owing to its benefits including deterministic entanglement and high controllability, is regarded as a highly promising scaling pathway. This scheme necessitates dividing the ion trap system into functional zones such as loading, storage, and interaction regions, with quantum information transferred via precise ion transport. Traditional macroscopic ion traps struggle to meet the scaling demands of QCCD. In this context, the surface-electrode ion trap (SEIT) is developed. SEITs create multiple trapping sites by fabricating micro-electrode arrays on a two-dimensional planar substrate. They offer outstanding advantages including compact size, high scalability, excellent compatibility with modern micro/nano-fabrication processes, and strong structural uniformity. Consequently, SEITs have become the primary technical platform for realizing the QCCD architecture, opening new pathways towards practical quantum computing. Progress This paper systematically reviews the research progress in SEITs concerning design, fabrication, performance evaluation, and on-chip integration, and provides an outlook on future development. In terms of design, starting from the trapping theory of SEITs, the article notes that their pseudopotential distribution is determined by the electrode geometry. It describes methods ranging from analytical approximations to high-precision numerical simulations for accurately characterizing the spatial potential generated by complex electrode structures. This provides a solid theoretical foundation for SEIT optimization. The evolution of one-dimensional (1D) scalable electrode designs is reviewed, tracing the development from 4-wire, 5-wire, and 6-wire to 7-wire traps, alongside approaches to enhance control freedom and flexibility for radial electric fields. To overcome the limitations of 1D scaling, various two-dimensional (2D) scaling schemes have been developed. For instance, Quantinuum's "quasi-2D" racetrack trap achieves the largest fully connected system with 56 qubits; designs utilizing "T", "Y", and "X" junctions to connect different zones address path branching issues, although further optimization of potential barriers and trap depth variations within junction regions is required; the quantum spring array (QSA) architecture, proposed by the University of Innsbruck, achieves coupling by controlling ion spacings within sub-registers, avoiding traditional split-merge operations, and demonstrates advantages like full connectivity, simplified operations, enhanced coupling rates, and potential fault tolerance. Regarding integrated design, incorporating on-chip optical components such as waveguides and microlenses significantly improves fluorescence collection efficiency and addressing capability while reducing the footprint of peripheral optics. Electrical integration encompasses passive filtering capacitors and active devices like complementary metal oxide semiconductor (CMOS) technology, offering effective solutions for independent multi-electrode control, reduced signal transmission noise, and minimized overall system size. For fabrication processes, SEITs are primarily manufactured using micro/nano-fabrication techniques. Material selection is a critical aspect of the process: substrate materials require balancing low radio-frequency (RF) loss with compatibility for processing complex structures; surface metals must combine low anomalous heating with good oxidation resistance; materials for integrated optical devices must match specific ion transition wavelengths; detector materials need high detection efficiency, low noise, and excellent cryogenic compatibility; materials for electrical integration require compatibility with CMOS processes and long-term stability under cryogenic, vacuum conditions. The standard fabrication sequence typically begins with wafer cleaning, followed by steps such as shielding layer preparation, insulator deposition, surface electrode layer plating and patterning, and critical void dielectric etching. A central objective of the entire process is achieving precise control over ultra-high surface flatness and controlled micro-roughness across all functional layers. This is essential for effectively suppressing various electric field noises originating from surface defects, abnormal grain boundary structures, and patch potential non-uniformity. To mitigate the "anomalous heating" effect caused by the extremely close proximity of ions to the electrodes, several advanced surface treatment solutions have been developed, including pulsed laser cleaning, inert gas ion beam bombardment, and plasma cleaning. Performance evaluation of SEITs focuses on three key dimensions: ion trap heating rate characteristics, chip electric field properties, and ion transport performance. For assessing heating rate characteristics, methods include sideband carrier ratio measurement, blue sideband transition analysis, and Doppler recooling schemes. Among these, deep learning-based phonon number determination methods, capable of distinguishing vibrational modes, show significant promise. In evaluating electric field performance, precise calibration of the electric fields generated by the electrodes and environmental stray fields is vital for ion transport manipulation. Experimental calibration overcomes the limitations of theoretical simulation, and trap potential calibration methods based on multi-parameter optimization enable accurate prediction of trap frequencies and effective control of transport positions. Regarding transport performance, evaluation emphasizes various modes including linear transport, separation/merging, direction-changing transport across junctions, ion position swapping, and inter-chip transport. The core objective is achieving fast operations with minimal heating. Conclusions and Prospects This paper comprehensively reviews the progress in SEITs across key areas: structural design (from 1D to 2D scaling architectures), fabrication processes (materials, micro-fabrication, surface treatment), performance evaluation (heating rate, electric fields, transport), and on-chip manipulation. SEITs, leveraging their excellent scalability and compatibility with modern fabrication techniques, combining with breakthroughs in on-chip photonic and electronic integration, provide a solid technical foundation for building integrated, scalable ion-trap quantum processors. As a key technology for large-scale quantum computing, particularly the QCCD architecture, its future development will focus on: developing multi-layer or 3D hybrid ion trap chips with higher integration and reconfigurable electrode layouts to enable fast, low-crosstalk, high-fidelity ion shuttling and stable storage; integrating large-scale, high-density electrode control electronics, utilizing advanced packaging technologies like through-silicon vias (TSVs) to couple thousands of low-noise, high-speed analog control signals in close proximity to the trap chip; implementing on-chip or near-chip integrated photonic networks for efficient, scalable quantum interconnects between different ion chains/modules; and exploring novel electrode materials, structures, and surface treatments to continuously suppress electrode noise, enhance trap depth stability, and extend ion coherence times. Ultimately, system-level integration and co-optimization will be the core challenge, requiring the seamless fusion of high-performance trapping, precise manipulation, efficient readout, fast communication, and powerful classical control. With continued breakthroughs in these key technologies, the SEIT platform is expected to demonstrate QCCD prototypes with hundreds of qubits in the near term, gradually progressing towards practical quantum processors equipped with quantum error correction capabilities, thereby opening the door to quantum advantage applications in specific domains.

Solid-state quantum emitters are pivotal for modern photonic quantum technology, yet their inherent spectral inhomogeneity imposes a critical challenge in pursuing scalable quantum network. Here, we develop a cryogenic-compatible strain-engineering platform based on a polydimethylsiloxane (PDMS) stamp, which we show can also work properly at cryogenic temperature. In-situ three-dimensional (3D) strain control is achieved for quantum dots (QDs) embedded in photonic nanostructures. The compliant PDMS enables independent tuning of emission energy and strong reduction of fine structure splitting (FSS) of single QDs, as demonstrated by a 7 meV spectral shift with a near-vanishing FSS in circular Bragg resonators and an unprecedented 15 meV tuning range in the micropillar. The PDMS-based 3D strain-engineering platform, compatible with diverse photonic structures at cryogenic temperature, provides a powerful and versatile tool for exploring fundamental strain-related physics and advancing integrated photonic quantum technology.

The development of an in situ technique that does not require complex apparatus can facilitate accurate and rapid total antioxidant capacity (TAC) detection. Herein, we developed a specific and sensitive colorimetric assay to evaluate the TAC of fruit juices using the red–green–blue (RGB) model.

We present a novel micro-fabrication technique for creating concave surfaces on the endfacets of photonic crystal fibers. A fiber fusion splicer is used to generate arc discharges to melt and reshape the fiber endfacet. This technique can produce large spherical concave surfaces with roughness as low as 0.12 nm in various types of photonic crystal fibers. The deviation of fabricated surface and a spherical profile in the region of 70 µm in diameter is less than 50 nm. The center of the concave surface and the fiber mode field are highly coincident with a deviation less than 500 nm. Finesse measurements have shown that a Fabry-Pérot cavity composed of the fiber fabricated using this method and a plane mirror maintains finesse of 20000. This method is easy to replicate, making it a practical and efficient approach to fabricate concave surface on fibers for open-access fiber Fabry-Pérot cavities.

Miniaturized and reconfigurable interfaces between confined optical modes within integrated photonic chips and structured light propagating in free space would serve as a cornerstone for fundamental optical science and modern photonic technology. In this work, we present nonlinear nanophotonic chip-space interfaces capable of flexibly generating and multi-dimensionally engineering structured light via injections of photons to on-chip waveguides. By harnessing the nonlinear Cherenkov radiation in integrated nonlinear microring resonators, we successfully tailor the spatial profile, polarization state, emission wavelength, topological charge and temporal wave packet of structured optical vortices, exhibiting reconfigurabilities and tuning ranges far beyond the state-of-the-art. To further showcase the capabilities of our platform, we use a single pump to generate multi-state integrated vortex microcombs in the visible range via synergistic χ(2) and χ(3) nonlinear optical processes. Our work bridges the research fields of structured light and integrated optics, providing unprecedented opportunities to spatiotemporal light generation, on-chip nonlinear optics and integrated quantum photonics.

Cavity-enhanced single quantum dots (QDs) are the main approach towards ultra-high-performance solid-state quantum light sources for scalable photonic quantum technologies. Nevertheless, harnessing the Purcell effect requires precise spectral and spatial alignment of the QDs' emission with the cavity mode, which is challenging for most cavities. Here we have successfully integrated miniaturized Fabry-Perot microcavities with a piezoelectric actuator, and demonstrated a bright single-photon source derived from a deterministically coupled QD within this microcavity. Leveraging the cavity-membrane structures, we have achieved large spectral tunability via strain tuning. On resonance, a high Purcell factor of ~9 is attained. The source delivers single photons with simultaneous high extraction efficiency of 0.58, high purity of 0.956(2) and high indistinguishability of 0.922(4). Together with its compact footprint, our scheme facilitates the scalable integration of indistinguishable quantum light sources on-chip, therefore removing a major barrier to the development of solid-state quantum information platforms based on QDs.

Single photons are pivotal building blocks for photonic quantum technologies. Semiconductor quantum dots are promising candidates for optimal single photon sources in terms of purity, brightness and indistinguishability. Here we embed quantum dots into bullseye cavities with a backside dielectric mirror to enhance the collection efficiency up to near 90%. Experimentally, we achieve a collection efficiency of 30%. The auto-correlation measurements reveal a multiphoton probability below 0.05±0.005. A moderate Purcell factor of 3.1 is observed. Furthermore, we propose a scheme for laser integration as well as fiber coupling. Our results represent a step forward to the practical plug-and-play single photon sources.

The melting of micro/nanoparticles considering the Soret effect in an alloy melt is studied in terms of the asymptotic method. The results reveal that the positive Soret coefficient weakens the dynamic disequilibrium near the interface, and then enhances the melting temperature of the particle and decreases the melting speed of the particle. The negative Soret coefficient strengthens the dynamic disequilibrium near the interface, and then reduces the melting temperature of the particle and increases the melting speed of the particle. The positive Soret coefficient weakens the accumulation of the solute flux near the interface and enhances the solute concentration. The negative Soret coefficient strengthens the accumulation of the solute flux near the interface and reduces the solute concentration. The size dependence of the melting temperature considering the Soret coefficient is quantitatively consistent with the experimental data, especially for the micro/nanoparticles with a radius smaller than 5 nm.

Stimulated Raman transition is a fundamental method to coherently manipulate quantum states in different physical systems. Phase-coherent dichromatic radiation fields matching the energy level splitting are the key to realizing stimulated Raman transition. Here we demonstrate a flexible-tuning, spectrum-clean and fiber-compatible method to generate a highly phase-coherent and high-power multi-tone laser. This method features the utilization of a broadband fiber Mach-Zehnder modulator working at carrier suppression condition and second harmonic generation. We generate a multi-tone continuous-wave 532 nm laser with a power of 1.5 Watts and utilize it to manipulate the spin and motional states of a trapped 171Yb+ ion via stimulated Raman transition. For spin state manipulation, we acquire an effective Rabi frequency of 2π × 662.3 kHz. Due to the broad bandwidth of the fiber modulator and nonlinear crystal, the frequency gap between tones can be flexibly tuned. Benefiting from the features above, this method can manipulate 171Yb+ and 137Ba+ simultaneously in the multi-species ion trap and has potential to be widely applied in atomic, molecular and optical physics.
