Heralded linear optical generation of Dicke states
Published on 2026-04-30 by Minhyeok Kang, Jaehee Kim, William J Munro, Seungbeom Chin and Joonsuk Huh @IOP SCIENCE
Abstract: Entanglement is a fundamental feature of quantum mechanics and a key resource for quantum information processing. Among multipartite entangled states, Dicke states are distinguished by their permutation symmetry, which provides robustness against particle loss and enables applications for quantum communication and computation. Although Dicke states have been realized in various platforms, most optical implementations rely on postselection, which destroys the state upon detection and prevents its[...]
Our summary: This work presents a linear-optical heralded scheme for generating arbitrary Dicke states using photons.

Abstract: A CoCrNi-AlTi medium-entropy alloy was fabricated via laser powder bed fusion (L-PBF), and its microstructural evolution and mechanical response during aging at 500–900 °C for 1 h were systematically investigated. The as-built alloy exhibits a hierarchical microstructure consisting of elongated columnar grains and dislocation-rich cellular substructures, which is associated with an excellent strength–ductility combination (YS: 848 MPa, UTS: 1136 MPa, EF: 3[...]
Our summary: The study investigates the effects of post-heat treatments on the microstructure and mechanical properties of a CoCrNi-AlTi medium-entropy alloy fabricated via laser powder bed fusion. Aging at temperatures between 500-900 °C enhances hardness and tensile strength, with peak performance noted at 800 °C. The research highlights the role of L-PBF-induced defect structures in influencing precipitation behavior and the strength-ductility trade-off during heat treatment.
