To this end, we consider different programs based on the restriction of the evolution to the set of separable (i.e., non-entangled) states, together with the discretization of the space of variables for numerical computations. As a first approach, we apply linear splitting methods to the restricted, continuous equations of motion derived from variational principles. We utilize an exchange interaction Hamiltonian to confirm that the numerical and analytical solutions coincide in the limit of small time steps. The application to different Hamiltonians shows the wide applicability of the method to detect dynamical entanglement. To avoid the derivation of analytical solutions for complex dynamics, we consider variational, numerical integration schemes, introducing a variational discretization for Lagrangians linear in velocities. Here, we examine and compare two approaches: one in which the system is discretized before the restriction is applied, and another in which the restriction precedes the discretization. We find that the ‘first-discretize-then-restrict’ method becomes numerically unstable, already for the example of an exchange-interaction Hamiltonian, which can be an important consideration for the numerical analysis of constrained quantum dynamics. Thereby, broadly applicable numerical tools, including their limitations, for studying entanglement over time are established for assessing the entangling power of processes that are used in quantum information theory.","lang":"eng"}],"date_created":"2026-06-05T07:37:43Z","department":[{"_id":"623"},{"_id":"15"},{"_id":"170"},{"_id":"706"},{"_id":"429"}],"type":"journal_article","status":"public","_id":"65777","publisher":"IOP Publishing","volume":59,"user_id":"75127","citation":{"apa":"Offen, C., Wembe Moafo, B.

Recently, it has been experimentally demonstrated that photonic platforms based on Gaussian boson sampling (GBS) are capable of performing these simulations. However, whether an actual GBS approach is required depends on the molecule under investigation. To develop a better understanding on the requirements for simulating vibronic spectra, we explore connections between theoretical approximations in physical chemistry and their photonic counterparts. Mapping these approximations into photonics, we show that for certain molecules the GBS approach is unnecessary. We place special emphasis on the linear coupling approximation, which in photonics corresponds to sampling from multiple coherent states. By implementing this approach in experiments, we demonstrate improved similarities over previously reported GBS results for formic acid and identify the particular attributes that a molecule must exhibit for this, and other approximations, to be valid. These results highlight the importance in forming deeper connections between traditional methods and photonic approaches.","lang":"eng"}],"related_material":{"link":[{"relation":"research_data","url":"https://doi.org/10.5281/zenodo.18969354"}]},"issue":"1","publication":"npj Quantum Information","volume":12,"user_id":"73665","_id":"65847","publisher":"Springer Science and Business Media LLC","status":"public","oa":"1","project":[{"name":"PhoQuant: Photonische Quantencomputer - Quantencomputing Testplattform","_id":"191"}],"citation":{"short":"J.-L.

We introduce a paradigm shift using a many‐body plasmonic architecture inspired by statistical mechanics. By moving toward the continuum limit, local geometric variations are statistically averaged out, effectively decoupling optical performance from microscopic disorder. We implement this concept via a lithography‐ and etching‐free, multi‐step dewetting strategy, creating wafer‐scale nanoclusters. This process strategically forms a robust many‐body system by introducing numerous small satellite nanoparticles between larger particles. Crucially, this design achieves a high collective enhancement that surpasses even optimized few‐body systems, despite having larger individual gaps. Under optimized conditions, these substrates exhibit a surface‐enhanced Raman scattering enhancement factor approaching 4 × 10^8 with unprecedented reproducibility (RSD of ∼10%). This scalable, low‐cost concept establishes a practical route toward reproducible wafer‐scale nanophotonic platforms for sensing, spectroscopy, and quantum technologies."}],"language":[{"iso":"eng"}],"article_number":"e71610","main_file_link":[{"url":"https://onlinelibrary.wiley.com/doi/10.1002/lpor.71610","open_access":"1"}],"doi":"10.1002/lpor.71610","publication_identifier":{"issn":["1863-8880","1863-8899"]},"author":[{"first_name":"Minjun","last_name":"Kim","full_name":"Kim, Minjun"},{"id":"103814","full_name":"Devaraj, Vasanthan","last_name":"Devaraj","first_name":"Vasanthan"},{"last_name":"Seo","first_name":"Hyeon‐Seok","full_name":"Seo, Hyeon‐Seok"},{"first_name":"Seong‐Jae","last_name":"Eom","full_name":"Eom, Seong‐Jae"},{"full_name":"Lee, Jeong‐Su","first_name":"Jeong‐Su","last_name":"Lee"},{"full_name":"Lee, Donghan","first_name":"Donghan","last_name":"Lee"},{"last_name":"Jeon","first_name":"Min Yong","full_name":"Jeon, Min Yong"},{"full_name":"Zentgraf, Thomas","last_name":"Zentgraf","orcid":"0000-0002-8662-1101","first_name":"Thomas","id":"30525"},{"first_name":"Jong‐Min","last_name":"Lee","full_name":"Lee, Jong‐Min"}],"title":"Engineering Disordered Many‐Particle Plasmonic Nanoclusters for Wafer‐Scale Uniform and Giant Electromagnetic Field Enhancement","year":"2026","article_type":"original","publication_status":"published","date_updated":"2026-07-22T05:52:38Z","oa":"1","citation":{"apa":"Kim, M., Devaraj, V., Seo, H., Eom, S., Lee, J., Lee, D., Jeon, M.

Here, we demonstrate a hybrid nonlinear optoelectronic device that enhances the detection efficiency of a (001)-oriented GaAs PIN photodiode under telecommunication-wavelength illumination, where absorption is intrinsically limited to two-photon absorption (2PA). Our approach relies on the integration of a transferred, nanopatterned 385 nm-thick (111)-oriented GaAs nanofilm acting as an on-chip nonlinear frequency-conversion layer. Elliptical GaAs nanoresonators are employed to enhance second-harmonic generation (SHG) resonantly, converting incident 1550 nm radiation into above-bandgap photons efficiently absorbed by the underlying diode. Spatially resolved current–voltage measurements reveal a pronounced enhancement of the detector response in regions covered by the nanoantennas. The device exhibits a low dark current, while the metasurface-covered regions show the largest current response under 1560 nm excitation compared to the bare GaAs(100) diode and the unstructured GaAs(111) film. These results establish a direct functional link between dielectric metasurface–based nonlinear frequency conversion and electrical photodetection, providing a viable route toward integrated sub-bandgap detection schemes."}],"publication":"Optics Express","issue":"16"},{"type":"dissertation","department":[{"_id":"15"},{"_id":"35"}],"oa":"1","date_created":"2026-02-01T11:59:30Z","place":"Paderborn","abstract":[{"lang":"ger","text":"In dieser Dissertation werden Aspekte von high-gain multimode SU(1,1) Interferometer theoretisch untersucht.

The parametric down-conversion (PDC) process utilized in these interferometers is theoretically described via integro-differential equations describing spatial evolution of the plane-wave operators. It is shown that for the phase sensitivity of these interferometers, supersensitivity can be reached provided that proper diffraction compensation is applied. The phase sensitivity improves if the gain is increased or if the number of effective modes is decreased. This comes at the cost of the phase-region width over which supersensitivity can be reached. Based on the Schmidt mode structure of SU(1,1) interferometers, a processing method is constructed which allows for the experimental retrieval of the levels of squeezing and anti-squeezing of the multimode state generated by the first PDC section of an SU(1,1) interferometer. It is then applied experimentally by collaborators and is found to be in good agreement with the theoretical predictions. Finally, SU(1,1) interferometers pumped with Laguerre-Gaussian beams are analyzed in the context of angular displacement measurements. As either the gain, the OAM index or the radial index of the pump are increased, the measurement uncertainty is decreased, ultimately allowing for supersensitive measurements. Generally, the behavior is the same as for the phase sensitivity."}],"citation":{"bibtex":"@book{Scharwald_2026, place={Paderborn}, title={Theoretical investigations of spatially multimode high-gain SU(1,1) interferometers}, DOI={10.17619/UNIPB/1-2491}, publisher={Universität Paderborn}, author={Scharwald, Dennis}, year={2026} }","ama":"Scharwald D.

For the rather segregated German educational system, this endeavour applies especially to primary education, where needs are still developing and pupils are not yet assigned to different types of schooling according to their needs and abilities.\r\n\r\nDespite a substantial amount of research on pupils’ basic psychological needs for autonomy, competence and social relatedness (Ryan et al., 2022), strategies that technology education teachers apply in this regard are not yet well understood. Besides interventional studies on technology education, indicating effectiveness of self‑directed and action‑oriented teaching and learning, there is a dearth of research on how teachers address different needs as a routine.\r\n\r\nThe purpose of the presented study is therefore to investigate and systematize actions and strategies teachers apply, and to specify how pupils' needs are considered when teaching technology education on a given topic.\r\n\r\nThe overall study used a mixed-methods approach to the question how pupils’ needs are characterized by themselves and by their teachers, and how they were taken into account in a lesson adapted and delivered by the teachers. In the sub-study presented here, participating primary school teachers were interviewed about their consideration of pupils’ needs whilst planning and conducting a technology education unit on the functionality of robots.\r\n\r\nThe results gained from qualitative content analysis of the interviews indicate that although the anticipation of different needs is considered challenging, teachers possess a substantiate amount of practices and strategies to take them into account.\r\n\r\nThe paper systematizes the practices teachers described in structured interviews within strategies and discusses the contribution of taking basic needs into account for inclusive technology education."}],"main_file_link":[{"url":"https://ecp.ep.liu.se/index.php/patt/article/view/1455","open_access":"1"}],"language":[{"iso":"eng"}],"doi":"10.3384/ecp213.1455","alternative_title":["On Teachers’ Practices and Strategies to Teach Technology Inclusively at Primary Level"],"title":"“They Really Need to Handle, Inspect, and Experience Things”","year":"2026","publication_identifier":{"issn":["1650-3686","1650-3740"]},"author":[{"full_name":"Schröer, Franz","first_name":"Franz","last_name":"Schröer"},{"full_name":"Tenberge, Claudia","last_name":"Tenberge","first_name":"Claudia"}],"date_updated":"2026-06-30T13:09:02Z","publication_status":"published","intvolume":" 218"},{"issue":"1","publication":"Nature Communications","related_material":{"link":[{"url":"https://static-content.springer.com/esm/art%3A10.1038%2Fs41467-026-74861-9/MediaObjects/41467_2026_74861_MOESM1_ESM.pdf","relation":"supplementary_material","description":"Supplementary notes to the main article"},{"description":"Datasets and code","relation":"supplementary_material","url":"https://doi.org/10.5281/zenodo.20396394"}]},"abstract":[{"text":"The two-qubit controlled-not (C-NOT) gate is an essential component for gate-based quantum circuits.

Here, we present a systematic optical investigation of large‐scale 3D AuNP assemblies fabricated via meniscus‐guided assembly, focusing on the reproducibility, spatial uniformity, and mode evolution of their plasmonic responses. Spatially‐resolved dark‐field scattering measurements reveal that high‐aspect‐ratio AuNP pillars exhibit uniform scattering spectra along their height and across different pillars, despite variations in geometry and structure. Electromagnetic simulations suggest that this robustness arises from a collective many‐particle plasmonic response that remains optically active despite structural perturbations. The corresponding near‐field and surface‐charge distributions remain spatially distributed under representative structural perturbations, consistent with volumetric averaging across the three‐dimensional assembly. Building on this robust platform, we introduce compositional modulation through a core–satellite architecture by incorporating smaller AuNPs. This yields a composition‐dependent spectral redistribution, including the emergence of an additional long‐wavelength spectral feature in the core–satellite assemblies. Wavelength‐dependent surface‐enhanced Raman scattering measurements reveal contrasting responses under 633 and 785 nm excitation, reflecting redistribution of local plasmonic coupling pathways.

Das Buddy-Programm wurde in den folgenden Jahren basierend auf den Rückmeldungen der Teilnehmenden weiterentwickelt. In diesem Beitrag werden die Evaluationsergebnisse des Buddy-Programms während der Jahrestagung 2025 vorgestellt und diskutiert.","lang":"ger"}],"related_material":{"link":[{"relation":"table_of_contents","url":"https://gdcp-ev.de/tagungsbaende/tagungsband-2026-band-46/"}]},"main_file_link":[{"url":"https://gdcp-ev.de/wp-content/uploads/securepdfs/2026/08/005_Buddy-Evaluation.pdf","open_access":"1"}],"language":[{"iso":"ger"}],"year":"2026","title":"Evaluation des Buddy-Programms der GDCP-Jahrestagung 2025","author":[{"full_name":"Zwick, Linda","last_name":"Zwick","first_name":"Linda"},{"full_name":"Bühler, Eva","first_name":"Eva","last_name":"Bühler"},{"id":"118219","full_name":"Weiler, David Christoph","orcid":"0000-0003-2164-0341","first_name":"David Christoph","last_name":"Weiler"}],"corporate_editor":["Gesellschaft für Didaktik der Chemie und Physik (GDCP)"],"date_updated":"2026-08-07T06:44:55Z","publication_status":"published"},{"project":[{"_id":"56","name":"TRR 142 - Project Area C"},{"name":"TRR 142: Maßgeschneiderte nichtlineare Photonik: Von grundlegenden Konzepten zu funktionellen Strukturen","_id":"53"},{"name":"TRR 142 ; TP: C10: Erzeugung und Charakterisierung von Quantenlicht in nichtlinearen Systemen: Eine theoretische Analyse","_id":"174"},{"name":"Computing Resources Provided by the Paderborn Center for Parallel Computing","_id":"52"}],"citation":{"ama":"Scharwald D, Sharapova P.

However, its multimode nature also makes it challenging to measure its properties. Recently [I. Barakat et al., Optica Quantum 3, 36 (2025)], a technique for the simultaneous measurement of squeezing of multiple broadband modes based on a phase-sensitive amplification approach was experimentally implemented using a setup that effectively corresponds to an SU(1,1) interferometer. Here, we aim to provide a complete theoretical analysis of the modal structure of (generally unbalanced) SU(1,1) interferometers and a detailed theoretical formal derivation of the framework for this technique. Utilizing the joint Schmidt decomposition of the transfer functions, we investigate the shape and phase profiles of the modes of the SU(1,1) interferometer and its components [parametric down-conversion (PDC) sections] for different parametric gain regimes. We discover a complicated interplay between the PDC modes and the modes of the entire interferometer, and analyze it by using their overlap coefficients as a similarity measure. Finally, we develop a rigorous processing method for the aforementioned multimode squeezing measurement technique and discuss necessary approximations to make this method experimentally feasible."}],"publication":"Physical Review Research","issue":"3","department":[{"_id":"975"},{"_id":"15"},{"_id":"623"},{"_id":"569"},{"_id":"170"},{"_id":"35"},{"_id":"429"},{"_id":"34"},{"_id":"502"}],"type":"journal_article","date_created":"2026-08-05T11:51:21Z","article_type":"original","intvolume":" 8","publication_status":"published","date_updated":"2026-08-12T14:29:44Z","author":[{"id":"55907","full_name":"Scharwald, Dennis","orcid":"0009-0007-5654-5412","first_name":"Dennis","last_name":"Scharwald"},{"id":"60286","full_name":"Sharapova, Polina","first_name":"Polina","last_name":"Sharapova"}],"publication_identifier":{"issn":["2643-1564"]},"year":"2026","title":"Characterization of spatial Schmidt modes in high-gain SU(1,1) interferometers","doi":"10.1103/ph64-ts39","language":[{"iso":"eng"}],"article_number":"033139","main_file_link":[{"open_access":"1","url":"https://journals.aps.org/prresearch/pdf/10.1103/ph64-ts39"}]},{"citation":{"bibtex":"@article{Houde_Roeder_Silberhorn_Brecht_Quesada_2026, title={Quantum fisher information analysis for absorption measurements with undetected photons}, volume={8}, DOI={10.1088/2515-7647/ae82a2}, number={3035013}, journal={Journal of Physics: Photonics}, publisher={IOP Publishing}, author={Houde, Martin and Roeder, Franz and Silberhorn, Christine and Brecht, Benjamin and Quesada, Nicolás}, year={2026} }","ama":"Houde M, Roeder F, Silberhorn C, Brecht B, Quesada N.

We calculate the QFI as a function of parametric gain for both full and signal-only detection access. For losses below 99% and low to moderate gain, the SU(1,1) configuration provides the largest QFI. At high gain and intermediate loss, the IC scheme performs best, while under extreme attenuation (transmission\r\n \r\n \r\n \r\n \r\n \r\n \r\n <\r\n \r\n \r\n \r\n 1%) the DL model becomes optimal.
