In particular, we consider a setup in which the probe is a maximally mixed marginal (MMM) state and the environmental state is completely mixed where the quantum advantage equals the amount of discord consumed for illumination. Through a conditional extremal analysis, we determine the range of accessible advantages for given values of entanglement and discord. At fixed discord, higher entanglement restricts the accessible advantage to higher values, making high entanglement sufficient for achieving high advantage. Conversely, at fixed entanglement, low discord limits the advantage to low values, indicating that high discord is necessary for high advantage in MMM states. These conclusions remain unchanged when alternative correlation measures, including relative entropy and Bures entanglement and geometric discord, are used. The consistency of our results across multiple conceptually distinct measures indicates that the observed resource-advantage relation is not an artifact of a specific quantifier, but a robust feature of the protocol within the family of MMM states. We finally find that in the high-noise regime (near-maximally-mixed state), quantum advantage is, to leading order, a linear function of the initial discord highlighting discord as the key resource for resilience to noise in the protocol.</p></div>","PeriodicalId":746,"journal":{"name":"Quantum Information Processing","volume":"25 11","pages":""},"PeriodicalIF":2.2,"publicationDate":"2026-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149189608","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here we demonstrate a halogen‐driven trade‐off between humidity and thermal stability in (BrPhTMN) 2 MnX 4 (X = Cl, Br, I) with a non‐hydrogen‐bonding cation. Replacing Cl with I dramatically increases the photoluminescence quantum yield (from 20.2% to 84.3%) but drastically reduces humidity resistance at 90% relative humidity (RH) (from ∼51 h for the bromide to <14 min for the iodide). Remarkably, the thermal stability trend is reversed: the iodide shows enhanced emission at 430 K, whereas the chloride is heavily quenched. This paradoxical thermal robustness of the iodide, despite its large electron–phonon coupling (Huang–Rhys factor S = 4.43), can be rationalized by the energy‐gap law for multiphonon relaxation. Raman spectroscopy reveals an exceptionally low Mn–I phonon frequency (111 cm −1 ), which exponentially suppresses multiphonon non‐radiative decay, effectively closing the non‐radiative channel even under strong coupling. Exploiting these orthogonal stabilities, we construct a dual‐stimulus encryption device responsive to specific humidity‐heat sequences. This work establishes a design principle for anti‐thermal‐quenching luminescent materials and opens avenues for advanced stimulus‐responsive systems.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"11 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2026-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149208464","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A 2D metasurface‐3D metastructure composite design is proposed to construct a Resonator‐Gyroid Synergistic Metamaterial (R‐GSM). This structure integrates a 2D indium tin oxide (ITO) array with a 3D carbon‐based gradient Gyroid network. By coupling the low‐frequency resonance of the 2D units with the high‐frequency impedance matching and multiple scattering of the 3D structure, a continuous energy dissipation path is established. The results indicate that the R‐GSM mitigates the low‐frequency thickness constraints dictated by the traditional quarter‐wavelength resonance model. A prototype with a thickness of 15 mm (0.25 g/cm 2 ) demonstrates ultra‐broadband absorption from 2.4 to 40.0 GHz. Furthermore, by scaling the thickness to 20 mm (0.32 g/cm 2 ), it achieves a broad absorption bandwidth of 182.8% (1.8–40.0 GHz, reflection loss < −10 dB), approaching theoretical limits. It also exhibits excellent wide‐angle incidence stability and polarization insensitivity, with measurements closely matching multiphysics simulations. Radar cross‐section (RCS) evaluations demonstrate that this structure can be conformally integrated with curved surfaces, significantly reducing the scattering signatures of targets. The multi‐dimensional heterogeneous integration strategy provides a reliable design approach for developing lightweight and ultra‐broadband electromagnetic stealth structures.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"9 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2026-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149208467","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Topological descriptions in terms of skyrmion numbers implicitly assume the compactness of the underlying manifold. While this concept works for constrained fields due to inherent integration boundaries, compactness is usually not fulfilled in extended optical fields. Here, we use time-resolved polarimetric photoemission microscopy to determine the electric field vectors of a surface plasmon polariton nanofocus on Au(111) with deep sub-wavelength spatial and sub-fs temporal resolution. The surface plasmon polaritons were excited with circularly polarized light at an Archimedean spiral that was milled into the Au surface by a focused ion beam. The full vectorial field information provided by polarimetric PEEM allows for a spatiotemporal analysis of the skyrmion number of the field texture. At a fixed time, the skyrmion number oscillates as a function of the radius. Furthermore, the skyrmion number oscillates in time. The experimental findings are compared to analytical calculations that lead to the same conclusion: a global skyrmion number cannot be assigned in such non-compact fields. Our results reveal the limitations of the skyrmion number for optical fields and motivate the search for new topological invariants suited for optical fields.","PeriodicalId":23,"journal":{"name":"ACS Photonics","volume":"1 1","pages":""},"PeriodicalIF":7.0,"publicationDate":"2026-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149210031","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Among them, discrete time crystals are recognized by the spontaneous generation of robust subharmonic oscillations. So far, most time crystals are restricted to exhibit a “period‐doubled” behavior. However, a fertile ground in time crystalline with period‐‐tupling has been suggested. Here we experimentally realize scalable period‐2‐tupling and period‐‐tupling in the one‐ (1D) and two‐dimensional (2D) photonic lattices, respectively. In this non‐interacting system, no spontaneous symmetry breaking occurs; instead, the period‐‐tupling arises from the preparation of specific superpositions of eigenmodes with quasienergy gaps of . All levels of the 2D spectrum are paired with different gaps, so that different response periods can be achieved by exciting different sites of the same lattice. The period ‐tupling is robust against perturbations over an extraordinarily long time evolution. The results may promote further research into arbitrary higher‐order time crystals in interacting photonic systems and into non‐equilibrium physics adopting Floquet driving. Next‐generation quantum devices, such as topologically protected quantum state registers, quantum sensors, and simulators, can also be inspired by this approach.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"20 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2026-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149208468","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
