Advances in Position‐Momentum Entanglement: A Versatile Tool for Quantum Technologies

Laser &Photonics Reviews, EarlyView.
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.

Integrated Photonic Modulator Circuit With Programmable Intensity and Phase Modulation Response

Laser &Photonics Reviews, EarlyView.
A platform‐agnostic programmable modulation circuit is introduced to enable tunable and universal optimization of integrated photonic modulators. By flexibly controlling carrier amplitude and phase, the approach adapts to diverse device characteristics without structural redesign.

Responsive Phase Gradient Metasurface for Laser Stealth and Dynamic Thermal Camouflage

Laser &Photonics Reviews, EarlyView.
The graphical abstract depicts a phase‐gradient metasurface enabling directional scattering and emissivity‐controlled thermal radiation. The engineered phase profile redistributes the reflected optical momentum, suppressing specular reflection and generating non‐specular scattering.

Parallel Multi‐Target Detection for Quantum LiDAR

Laser &Photonics Reviews, EarlyView.
Parallel multi‐target detection is achieved in quantum LiDAR with a single‐pixel quantum readout. Direction and distance information are extracted together, allowing multiple objects to be distinguished under noisy low‐light conditions and pointing to a new strategy for scan‐free quantum remote sensing.

Optimal Universal Bounds for Waves With Varied Coherence Based on Supremum and Infimum Coherence Spectra

Laser &Photonics Reviews, EarlyView.
Coherence variation is ubiquitous in nature, yet determining how it constrains physical observables remains challenging for multimode waves. To address this challenge, this work establishes a majorization‐based theory that identifies the supremum and infimum in the set of input coherence spectra, which provide optimal universal bounds for any linear ...

Using synthetic models to understand the detecting ability of ground‐penetrating radar for water‐conducting structures in the bedrock of formerly glaciated site

Near Surface Geophysics, EarlyView.
Abstract Utilizing synthetic models for the interpretation of ground‐penetrating radar (GPR) profiles can aid in the detection of hydrogeological structures by identifying their signatures. In this study, finite difference (FD) forward modelling was used to understand the detection ability of 50 MHz GPR for (1) the quaternary deposit–bedrock contact ...

Using participatory scenario planning to explore the synergies and trade‐offs from upland treescape expansion

People and Nature, EarlyView.
Abstract The future of land use in the UK uplands is highly debated, with growing interest in increasing tree cover and other land use changes, alongside a desire to maintain traditional land use patterns and practices. Treescape expansion is likely to result in synergies and trade‐offs between different outcomes, so integrating stakeholder preferences

Technical wildness: Modernity, romanticism, and the technocratic turn in Scottish rewilding

People and Nature, EarlyView.
Abstract Technical wildness is a new and increasingly influential culture of nature. This paper marks its emergence in Scotland in the early 2020s. Focusing on Scotland's rapidly evolving land management sector, the paper traces how private rewilding companies position science‐led land management and natural capital markets as the most effective ...
