    查看更多>>摘要：To establish a scalable and secure quantum network,a critical milestone is advancing from basic point-to-point quantum key distribution(QKD)systems to the development of inherently multi-user protocols designed to maximize network capacity.Here,we propose a quantum passive optical network(QPON)protocol based on continuous-variable(CV)systems,particularly the quadrature of the coherent state,which enables deterministic,simultaneous,and high-rate secret key generation among all network users.We implement two protocols with different trust levels assigned to the network users and experimentally demonstrate key generation in a quantum access network with 8 users,each with an 11 km span of access link.Depending on the trust assumptions about the users,we reach 1.5 and 2.1 Mbits/s of total network key generation(or 0.4 and 1.0 Mbits/s with finite-size channels estimation).Demonstrating the potential to expand the network's capacity to accommodate tens of users at a high rate,our CV-QPON protocols open up new possibilities in establishing low-cost,high-rate,and scalable secure quantum access networks serving as a stepping stone towards a quantum internet.

    查看更多>>摘要：The detection of gravitational waves has ushered in a new era of observing the universe.Quantum resource advantages offer significant enhancements to the sensitivity of gravitational wave observatories.While squeezed states for ground-based gravitational wave detection have received marked attention,the generation of squeezed states suitable for mid-to-low-frequency detection has remained unexplored.To address the gap in squeezed state optical fields at ultra-low frequencies,we report on the first direct observation of a squeezed vacuum field until Fourier frequency of 4 millihertz with the quantum noise reduction of up to 8.0 dB,by the employment of a multiple noise suppression scheme.Our work provides quantum resources for future gravitational wave observatories,facilitating the development of quantum precision measurement.

    查看更多>>摘要：Mid-infrared(MIR)fiber lasers are important for a wide range of applications in sensing,spectroscopy,imaging,defense,and security.Some progress has been made in the research of MIR fiber lasers based on soft glass fibers,however,the emission range of rare-earth ions and the robustness of the host materials are still a major challenge for MIR fiber lasers.The large number of gases provide a variety of optical transitions in the MIR band.When combined with recent advances in low-loss hollow-core fiber(HCF),there is a great opportunity for gas-filled fiber lasers to further extend the radiation to the MIR region.Here,a 4.8-μm CO-filled silica-based HCF laser is reported for the first time.This is enabled by an in-house manufactured broadband low-loss HCF with a measured loss of 1.81 dB/m at 4.8 μm.A maximum MIR output power of 46 mW and a tuning range of 180 nm(from 4644 to 4824 nm)are obtained by using an advanced 2.33-μm narrow-linewidth fiber laser.This demonstration represents the longest-wavelength silica-based fiber laser to date,while the absorption loss of bulk silica at 4824 nm is up to 13,000 dB/m.Further wavelength expansion could be achieved by changing the pump absorption line and optimizing the laser structure.

    Multi-particle quantum walks on 3D integrated photonic chip

    3129-3138页
    查看更多>>摘要：Quantum walks provide a speed-up in computational power for various quantum algorithms and serve as inspiration for the construction of complex graph representations.Many pioneering works have been dedicated to expanding the experimental state space and the complexity of graphs.However,these experiments are mostly limited to small experimental scale,which do not reach a many-body level and fail to reflect the multi-particle quantum interference effects among non-adjacent modes.Here,we present a quantum walk with three photons on a two-dimensional triangular lattice,which is mapped to a 19 x 19 x 19 high-dimensional state space and constructs a complex graph with 6859 nodes and 45,486 edges.By utilizing the statistical signatures of the output combinations and incorporating machine learning techniques,we successfully validate the nonclassical properties of the experiment.Our implementation provides a paradigm for exponentially expanding the state space and graph complexity of quantum walks,paving the way for surmounting the classical regime in large-scale quantum simulations.

    Structured light analogy of quantum squeezed states

    3139-3150页
    查看更多>>摘要：Quantum optics has advanced our understanding of the nature of light and enabled applications far beyond what is possible with classical light.The unique capabilities of quantum light have inspired the migration of some conceptual ideas to the realm of classical optics,focusing on replicating and exploiting non-trivial quantum states of discrete-variable systems.Here,we further develop this paradigm by building the analogy of quantum squeezed states using classical structured light.We have found that the mechanism of squeezing,responsible for beating the standard quantum limit in quantum optics,allows for overcoming the"standard spatial limit"in classical optics:the light beam can be"squeezed"along one of the transverse directions in real space(at the expense of its enlargement along the orthogonal direction),where its width becomes smaller than that of the corresponding fundamental Gaussian mode.We show that classical squeezing enables nearly sub-diffraction and superoscillatory light focusing,which is also accompanied by the nanoscale phase gradient of the size in the order of λ/100(λ/1000),demonstrated in the experiment(simulations).Crucially,the squeezing mechanism allows for continuous tuning of both features by varying the squeezing parameter,thus providing distinctive flexibility for optical microscopy and metrology beyond the diffraction limit and suggesting further exploration of classical analogies of quantum effects.

    Dynamic control and manipulation of near-fields using direct feedback

    查看更多>>摘要：Shaping and controlling electromagnetic fields at the nanoscale is vital for advancing efficient and compact devices used in optical communications,sensing and metrology,as well as for the exploration of fundamental properties of light-matter interaction and optical nonlinearity.Real-time feedback for active control over light can provide a significant advantage in these endeavors,compensating for ever-changing experimental conditions and inherent or accumulated device flaws.Scanning nearfield microscopy,being slow in essence,cannot provide such a real-time feedback that was thus far possible only by scattering-based microscopy.Here,we present active control over nanophotonic near-fields with direct feedback facilitated by real-time near-field imaging.We use far-field wavefront shaping to control nanophotonic patterns in surface waves,demonstrating translation and splitting of near-field focal spots at nanometer-scale precision,active toggling of different near-field angular momenta and correction of patterns damaged by structural defects using feedback enabled by the real-time operation.The ability to simultaneously shape and observe nanophotonic fields can significantly impact various applications such as nanoscale optical manipulation,optical addressing of integrated quantum emitters and near-field adaptive optics.

    Long-range enhancement for fluorescence and Raman spectroscopy using Ag nanoislands protected with column-structured silica overlayer

    3158-3170页
    查看更多>>摘要：We demonstrate long-range enhancement of fluorescence and Raman scattering using a dense random array of Ag nanoislands(AgNIs)coated with column-structured silica(CSS)overlayer of over 100 nm thickness,namely,remote plasmonic-like enhancement(RPE).The CSS layer provides physical and chemical protection,reducing the impact between analyte molecules and metal nanostructures.RPE plates are fabricated with high productivity using sputtering and chemical immersion in gold(l)/halide solution.The RPE plate significantly enhances Raman scattering and fluorescence,even without proximity between analyte molecules and metal nanostructures.The maximum enhancement factors are 107-fold for Raman scattering and 102-fold for fluorescence.RPE is successfully applied to enhance fluorescence biosensing of intracellular signalling dynamics in HeLa cells and Raman histological imaging of oesophagus tissues.Our findings present an interesting deviation from the conventional near-field enhancement theory,as they cannot be readily explained within its framework.However,based on the phenomenological aspects we have demonstrated,the observed enhancement is likely associated with the remote resonant coupling between the localised surface plasmon of AgNIs and the molecular transition dipole of the analyte,facilitated through the CSS structure.Although further investigation is warranted to fully understand the underlying mechanisms,the RPE plate offers practical advantages,such as high productivity and biocompatibility,making it a valuable tool for biosensing and biomolecular analysis in chemistry,biology,and medicine.We anticipate that RPE will advance as a versatile analytical tool for enhanced biosensing using Raman and fluorescence analysis in various biological contexts.

    Shape optimization for high efficiency metasurfaces:theory and implementation

    查看更多>>摘要：Complex non-local behavior makes designing high efficiency and multifunctional metasurfaces a significant challenge.While using libraries of meta-atoms provide a simple and fast implementation methodology,pillar to pillar interaction often imposes performance limitations.On the other extreme,inverse design based on topology optimization leverages non-local coupling to achieve high efficiency,but leads to complex and difficult to fabricate structures.In this paper,we demonstrate numerically and experimentally a shape optimization method that enables high efficiency metasurfaces while providing direct control of the structure complexity through a Fourier decomposition of the surface gradient.The proposed method provides a path towards manufacturability of inverse-designed high efficiency metasurfaces.
