However, there are limited efficient ways to produce such entanglement due to the large frequency mismatch between the two regimes. Here, a new mechanism is presented to prepare microwave‐optics entanglement based on a hybrid system of two coupled opto‐ and magnomechanical microspheres, i.e., an yttrium‐iron‐garnet (YIG) sphere and a silica sphere. The YIG sphere holds a magnon mode and a vibration mode induced by magnetostriction, while the silica sphere supports an optical whispering‐gallery mode and a mechanical mode coupled via an optomechanical interaction. The two mechanical modes are close in frequency and directly coupled via physical contact of the two microspheres. It is shown that by simultaneously activating the magnomechanical (optomechanical) Stokes (anti‐Stokes) scattering, stationary entanglement can be established between the magnon and optical modes via mechanics‐mechanics coupling. This leads to stationary microwave‐optics entanglement by further coupling the YIG sphere to a microwave cavity and utilizing the magnon‐microwave state swapping. The protocol is within reach of current technology and may become a promising new approach for preparing microwave‐optics entanglement, which finds unique applications in hybrid quantum networks and quantum information processing with hybrid quantum systems.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"114 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2024-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142905020","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, typical chiral transmission devices primarily operate within the 1.55 µm waveband and encounter the wavelength‐dependent mode mismatch, which constrains operational range and degrades mode purity. In this study, we address these limitations by introducing metamaterial waveguides to tailor the requisite optical properties and achieve ultra‐broad‐bandwidth and ultra‐high‐purity chiral mode switching at 1.55 µm and beyond. Simulation results spanning the optical communication and 2 µm wavebands show near‐unity transmission efficiency and high mode purity (> 98.8%) across a record 500 nm bandwidth. Moreover, experimental results at 2 µm waveband reveal an average transfer efficiency of < 1 dB and high mode purity exceeding 95% within a setup‐limited bandwidth of 85 nm.

Under a structured optical pump, the population of atoms in the ground state could be efficiently controlled by tuning the chirality and intensity of optical fields, and thus the optical response of the medium is programmable in both space and time. The potential of this approach is demonstrated by engineering the spatial distribution of the complex susceptibility tensor of the medium in photonic structures, which enables the realization of nonreciprocal optical effects. Specifically, the advantages of chiral interaction between atoms and photons are investigated in an atom‐cladded waveguide, theoretically showing that strong, rapidly switchable, and reconfigurable isolation of optical signals in a selected optical mode is possible.

Initial meta-lenses strive for uniform spectral responses over broadband for full-color imaging. Nevertheless, enhancing wavelength selectivity remains crucial for specific applications, such as fluorescence imaging and augmented reality, requiring specific wavelengths. Current methods struggle to balance nonlocal resonance with local phase control or introduce an additional filter layer. Here, an all-dielectric resonant meta-lens for wavelength-selective focusing based on the Fresnel zone plate design is experimentally demonstrated. The coupling between nonlocal lattice resonance and local Mie-type resonance is effectively manipulated to control the reflection and bandwidth. Without considering the balance between nonlocal resonance excitation and local phase control, the resonant meta-lens can reflectively focus at a resonant wavelength of 460 nm while allowing normal transmission at non-resonant wavelengths, which is generally restricted in conventional metallic counterparts. Simulation (experimental) results indicate a high color purity of 90% (66%), surpassing those of meta-lenses with filtering functions. A multi-resonant meta-lens is further designed for red, green, and blue colors. This work offers enhanced options for wavelength-selective meta-lenses, expanding their potential in optical imaging and display applications.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"54 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2024-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142902180","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, it has remained an untouched research topic to achieve regulated rotation on solid surfaces at microscale, wherein friction serves as the dominant yet formidable external force. Here, this gap is bridged through an all‐optical approach. By utilizing pulsed light with an elongated Gaussian profile and twisting it relative to an illuminated object, chiral vortexes are introduced in both the optothermally excited elastic waves and the as‐induced surface friction, endowing the object with a restoring torque. Self‐regulation of the rotor and refueling of the chirality synergistically modulate the rotational motion. On this basis, orientation of the rotor can be adjusted arbitrarily by any specific angle, achieving an angular resolution of rad and rotation speed up to 10 rpm. Furthermore, the composite motion is demonstrated, combining both rotational and translational modes into the light field‐rotor system. The proposed technique extends the capability of optical manipulation on frictional solid surfaces by exploring the relation between the symmetry‐breaking condition and the modes of locomotion, which provides theoretical guidance and practical opportunities for building reconfigurable devices on solid substrates.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"15 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2024-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142887691","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, strongly coupled systems formed by monolayer WS2, spatially separated monolayer MoS2, and Ag nanoholes (Ag‐NHs) with square lattice are investigated by using an ultrafast pump‐probe approach. From transient absorption spectra of the prototypical Ag‐NHs/WS2/SiO2 (10 nm)/MoS2 heterostructures, a Rabi splitting up to 80 meV is observed, which is almost 21/2 times larger than that of each individual component. The result is as expected since Rabi splitting depends on the square root of the layer number involved, thus suggesting that the A exciton of WS2 and spatially separated B exciton of MoS2 are entangled by the Bloch‐surface plasmon polariton mode. Additionally, whether the donor or the acceptor is excited, the bleaching signals in the heterostructures all appear instantaneously and exhibit exactly the same dynamic process, further clearly highlighting the presence of quantum mechanically entangled states. From another perspective, such entangled states assist remarkably efficient energy transfer, which is also demonstrated by significantly enhanced fluorescence emission from MoS2, with an enhancement factor of 25.

Variational learning is a promising avenue that leverages classical optimization techniques to enhance quantum advantages on NISQ devices. However, most variational algorithms are circuit‐model‐based and encounter challenges when implemented on integrated photonic circuits, because they involve explicit decomposition of large quantum circuits into sequences of basic entangled gates, leading to an exponential decay of success probability due to the non‐deterministic nature of photonic entangling gates. Here, a variational learning approach is presented for designing quantum photonic circuits, which directly incorporates post‐selection and elementary photonic components into the training process. The complicated circuit is treated as a single nonlinear logical operator and a unified design is discovered for it through variational learning. Engineering an integrated photonic chip with automated control achieved by genetic algorithm, the internal parameters of the chip are adjusted and optimized in real‐time for task‐specific cost functions. A simple case of designing photonic circuits for a single ancilla CNOT gate with improved success rate is utilized to illustrate how the proposed approach works, and then the approach is applied to the first demonstration of quantum stochastic simulation using integrated photonics.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"5 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2024-12-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142887696","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
