Universal convolution from wave dynamics: photonic processing and encryption in synthetic dimension
Abstract Convolution, a cornerstone of signal processing and optical neural networks, has traditionally been implemented by mapping mathematical operations onto complex hardware. Here, we overcome this challenge by revealing that wave dynamics in translation-symmetric lattices intrinsically performs convolution, with the dispersion relation uniquely defining the complex-valued kernel.
Monolithic integration of continuous-variable cluster-state generation, manipulation and measurement
Abstract Photonic integrated circuits provide a controllable and scalable platform for quantum information processing. In particular, continuous-variable integrated photonic quantum devices—which encode quantum information in the quadratures of optical qumodes—provide distinct advantages, although generating multimode entanglement in such systems has remained a key challenge.

AI passing and invisible authenticity labor: trust vulnerabilities and inequality in China's short-video creator economy
Abstract Generative AI is increasingly embedded in China's short-video production, yet on authenticity-oriented platforms its visible use can be discrediting. Drawing on 16 in-depth interviews with creators active on Xiaohongshu and Douyin, this article introduces AI passing: creators' strategic efforts to conceal and humanize AI-assisted drafts so that outputs plausibly appear human-authored.

Continuous-variable multipartite entanglement in an integrated microcomb - Nature
Abstract The generation of large-scale entangled states is crucial for quantum technologies, such as quantum computation1, communication2 and metrology3. Integrated quantum photonics that enables on-chip encoding, processing and detection of quantum light states offers a promising platform for the generation and manipulation of large-scale entangled states4,5.
Coherent Signal DOA Estimation Method Based on Space-Time-Coding Metasurface
4.3. Performance Comparison Firstly, to compare the DOA estimation resolution of the algorithm proposed in this paper with the existing spatial smoothing MUSIC (SS-MUSIC) algorithm, a comparative experiment was conducted at two angles, 0° and 5°, under the same angular interval. The results, as shown in the and , indicate that the method proposed in this paper can resolve the DOA of two coherent signals with a 5° interval, while the spatial smoothing MUSIC algorithm struggles to do so.
Continuous-variable entanglement swapping with photon subtraction
Entanglement swapping, which establishes entanglement between two independent and distant entangled states, is a key element of a quantum repeater in an entanglement-based quantum network. In continuous-variable (CV) entanglement swapping, it is essential to enhance the entanglement of entanglement swapping because it decreases with loss and noise in the quantum channel.

Experimental investigation of a precast segmental Twin‐Deck box girder bridge simultaneously erected with double bridge erection gantries
Abstract Precast segmental construction can shorten the construction time of the bridge and reduce the impacts on traffic and environment. Thus, this approach has been widely used in many countries. The relevant literature suggests that in the existing segmental precast bridges, nearly all of the centerlines of the girders are aligned with the centerline of the bridge piers. This paper introduces a wide urban viaduct comprising twin separate box girder cells using segmental prefabrication.
A Clutter Parameter Estimation Method Based on Origin Moment Derivation
Abstract : Parameter estimation is significant to prediction and estimation in the field of radar clutter characteristics. Therefore, it is necessary to study the problem of parameter estimation. The K-distribution is a commonly used model in sea clutter, which is a two-parameter model with shape parameters and scale parameters. The value of the shape parameters should be greater than 0. Moment estimation is usually used to estimate the parameters of the K-distribution.
Remote preparation and manipulation of squeezed light
Abstract Remote state preparation enables one to create and manipulate a quantum state based on the shared entanglement between distant nodes. Here, we experimentally demonstrate remote preparation and manipulation of squeezed light. By performing a homodyne projective measurement on one mode of the continuous variable entangled state at Alice’s station, a squeezed state is created at Bob’s station.
