Advances in Position‐Momentum Entanglement: A Versatile Tool for Quantum Technologies
Position–momentum entanglement constitutes a high‐dimensional continuous‐variable resource in quantum optics. Recent advances in its generation, characterization, and control are reviewed, with emphasis on spontaneous parametric down‐conversion and modern measurement techniques.

This work presents a lithography‐ and etching‐free dewetting strategy that assembles many‐particle gold nanostructures into uniform plasmonic substrates at the wafer scale. By forming satellite nanoparticles between larger ones, the method achieves giant and highly reproducible electromagnetic enhancement.

Micrometer‐sized flower‐shaped metamaterial magnetic flux concentrators are fabricated directly around nano and micromagnetic samples, enabling local field enhancement. Integrated into magnetic sensitive photoemission electron microscopy, they extend the available magnetic field range by up to a factor of five.

In this manuscript, we propose to suppress the metasurface's undesired dispersion to widen its working range, while preserving the desired one to preserve the function. As shown in the figure, through a method of reversed superimposition (RS), we have implemented the idea on a metasurface for the dual‐band EM window at large angles (≥ 60°).

Integrated optical phased arrays are emerging as scalable engines for solid‐state beam steering and programmable wavefront control. This Review maps the field from beam‐steering principles and core building blocks to material platforms, system‐level bottlenecks, and application frontiers, highlighting how heterogeneous integration, aperiodic ...
