As a\r\nresult, proving QMA-hardness of approximation for ground state energy\r\nestimation has remained elusive. Recently, it was shown [Bittel, Gharibian,\r\nKliesch, CCC 2023] that a natural problem involving variational quantum\r\ncircuits is QCMA-hard to approximate within ratio N^(1-eps) for any eps > 0 and\r\nN the input size. Unfortunately, this problem was not related to quantum CSPs,\r\nleaving the question of hardness of approximation for quantum CSPs open. In\r\nthis work, we show that if instead of focusing on ground state energies, one\r\nconsiders computing properties of the ground space, QCMA-hardness of computing\r\nground space properties can be shown. In particular, we show that it is (1)\r\nQCMA-complete within ratio N^(1-eps) to approximate the Ground State\r\nConnectivity problem (GSCON), and (2) QCMA-hard within the same ratio to\r\nestimate the amount of entanglement of a local Hamiltonian's ground state,\r\ndenoted Ground State Entanglement (GSE). As a bonus, a simplification of our\r\nconstruction yields NP-completeness of approximation for a natural k-SAT\r\nreconfiguration problem, to be contrasted with the recent PCP-based PSPACE\r\nhardness of approximation results for a different definition of k-SAT\r\nreconfiguration [Karthik C.S. and Manurangsi, 2023, and Hirahara, Ohsaka, STOC\r\n2024].","lang":"eng"}],"citation":{"bibtex":"@inproceedings{Gharibian_Hecht, title={Hardness of approximation for ground state problems}, volume={386}, number={48}, booktitle={51st International Symposium on Mathematical Foundations of Computer Science (MFCS)}, author={Gharibian, Sevag and Hecht, Carsten}, pages={1–19} }","ama":"Gharibian S, Hecht C.

Kalläne, H. Kullmann, in: 2026."},"abstract":[{"text":"Die Fridays-for-Future-Bewegung (FFF) hat gezeigt, dass Schüler*innen zu zentralen politischen Akteur*innen werden können. Insbesondere in der Anfangsphase der sogenannten Klimastreiks wurde die Bewegung stark von Jugendlichen getragen; weibliche Teilnehmende sowie solche mit (angestrebtem) Abitur dominierten die Proteste (Sommer et al., 2020). Eine ähnliche Verbindung zwischen Bildungsstand und politischem Interesse spiegelt die Shell-Studie von 2019 wider, in der deutlich mehr Jugendliche mit (angestrebtem) Abitur angaben, sich politisch zu interessieren, als solche auf anderen Bildungswegen (Schneekloth & Albert, 2019). Über den Zusammenhang von Schule und politischer Partizipation im Kontext von FFF ist wenig bekannt; insbesondere fehlen Studien mit Fokus auf die Schulform oder den sonderpädagogischen Förderstatus der Teilnehmenden. Diesem Forschungsdesiderat widmet sich der vorliegende Beitrag, in dem die Bedeutung der Schule für die Förderung politischer Partizipation im Kontext von FFF unter besonderem Augenmerk auf die Schüler*innen mit sonderpädagogischem Förderbedarf (SPF) beleuchtet wird. \r\nEntsprechende Erkenntnisse sind u.a. vor dem Hintergrund von Interesse, dass das Einbeziehen aller Schüler*innen in Prozesse politischer Partizipation – im Einklang mit inklusionsbezogenen Qualitätstableaus wie dem Index für Inklusion (Booth & Ainscow, 2011) – eine zentrale schulpädagogische Forderung darstellt (z.B. Felder, 2024; Schramme, 2024). Bildungstheoretisch lässt sich dies u.a. durch Klafkis Konzept der Allgemeinbildung fundieren, das Selbstbestimmungs-, Mitbestimmungs- und Solidaritätsfähigkeit als Kernelemente einer Bildung für alle umfasst und epochaltypische Schlüsselprobleme wie die „Umweltfrage“ (Klafki, 2007, S. 58) ins Zentrum einer kritisch-reflexiven Bearbeitung rückt. Die UN-Nachhaltigkeitsziele unterstreichen die Bedeutung von Bildung für die Bearbeitung globaler Krisen in einer vielfältigen Gesellschaft (UNESCO, 2020). FFF stellt in diesem Kontext einen besonderen Untersuchungsgegenstand dar, da die Bewegung einerseits als außerschulischer Lernort fungieren kann (Hörsch et al., 2023), als „Schulstreik“ andererseits aber auch in direkter Beziehung zur Institution Schule steht. \r\nSchule spielt laut einer Befragung von FFF-Teilnehmenden neben Freund*innen und sozialen Netzwerken eine zentrale Rolle in der Mobilisierung für die Demonstrationsteilnahme (Koos, 2019). Als Prädiktor für die Protestteilnahme dominieren gesellschaftliche Motive, wobei FFF als Möglichkeit wahrgenommen wird, sich aktiv für gesellschaftliche Veränderungsprozesse einzusetzen und Einfluss auf politische Entscheidungsprozesse zu nehmen (Costa & Wittmann, 2021). Befragungen explizit unter Schüler*innen ergaben zudem, dass die Teilnahmemotivation oft durch eigene Werte und Normen, Peers sowie die Identifikation mit anderen Protestierenden begründet wird (Wallis & Loy, 2021). Offen bleibt, ob die schulische Bearbeitung von Themen wie dem Klimaaktivismus dazu führen kann, dass deren politische Schärfe verloren geht, oder ob (und wie) die politischen Interessen von Kindern und Jugendlichen durch die unterrichtlichen Informationen und Debatten gestärkt werden können (Budde, 2021). \r\nIm Rahmen des Projekts FFFinklusiv wurde in Bezug auf mehrere schulische Faktoren untersucht, inwiefern diese jeweils die Motivation von Schüler*innen mit und ohne sonderpädagogischen Förderbedarf zur Teilnahme an FFF beeinflussen. 637 Jugendliche aus acht Förderschulen und vier Gesamtschulen nahmen 2020 an einer Befragung teil. Per explorativer und konfirmatorischer Faktorenanalyse wurde die Skala „Protestmotivation“ entwickelt und in einer Mehrebenenanalyse unter Einbezug der Klassenebene untersucht. \r\nDie Auswertung zeigt drei signifikante Einflussfaktoren: Das Geschlecht, wobei Mädchen eine höhere Motivation aufweisen (b = 0.77, t(530) = 6.50, p < .001), die Thematisierung von FFF im Unterricht (b = 0.45, t(530) = 3.51, p < .001) sowie den gemeinsamen Protestbesuch mit der Klasse (b = 0.53, t(530) = 2.02, p = .044). Schulform und SPF haben keinen signifikanten Effekt. In einer Teilstichprobe mit Protest-Teilnehmenden (n = 71) zeigen sich keine Unterschiede für Gesamtschüler*innen mit und ohne SPF. Eine signifikant höhere Motivation ergibt sich für Förderschüler*innen im Vergleich zu Gesamtschüler*innen mit SPF (b = 1.84, t(20) = 2.07, p = .051).\r\nDie Ergebnisse betonen die Bedeutung von Schule für die politische Partizipation aller Schüler*innen. Sie zeigen auf, dass die Motivation zur Teilnahme an themenbezogenen Demonstrationen durch die Berücksichtigung im Unterricht gefördert werden kann, weitestgehend unabhängig von Schulform und Förderstatus. \r\n\r\nKeywords: Fridays for Future, politische Partizipation, sonderpädagogischer Förderbedarf, Protestmotivation, Klimaaktivismus\r\n\r\nLiteratur:\r\nBooth, T., & Ainscow, M.

However, incorporating optical nonlinear activation functions to make DNNs a feasible alternative to their electronic counterpart remains a challenge. Here, we investigate the inclusion of second-harmonic generation (SHG), as one of the simplest and most efficient types of optical nonlinearities, in DNNs. We numerically investigate the impact of SHG on the performance of classification tasks in an all-optical nonlinear DNN. Specifically, we investigate and discuss the essential requirements for an effective arrangement of a SHG activation in single and multilayer DNNs. We find that the performance, in terms of classification accuracy and class contrast, is affected strongly by the positioning of the SHG activation. Finally, we discuss and outline the constraints for including SHG in an experimental realization. Taking these constraints into account, we estimate the power-related efficiency of the nonlinear DNN system. Overall, our results provide a path towards implementing nonlinear DNNs using the SHG process.</jats:p>"}],"publication":"Optics Express","issue":"19","department":[{"_id":"975"}],"type":"journal_article","date_created":"2026-09-12T10:09:12Z","status":"public","volume":34,"user_id":"115260","_id":"67134","publisher":"Optica Publishing Group","citation":{"apa":"Braasch, M., Kartashova, A., Krasikov, S., Goi, E., Pertsch, T., &#38; Saravi, S.

The gain-dependent evolution of these states is examined starting from the low-gain regime, which includes both highly correlated and nearly uncorrelated cases. For the unapodized configuration, our simulated results show a monotonic increase in spectral purity with gain, whereas for some of the apodized configuration, they exhibit a nonmonotonic dependence, initially decreasing and then recovering at higher gain. By combining Schmidt-mode analysis with a group-velocity-based interpretation, we explain why different dispersion conditions exhibit distinct gain-dependent behavior, specifically that rapid purification occurs when the pump group velocity lies between those of the signal and idler. Our study shows that the evolution of spectral purity is governed primarily by the underlying dispersion of the waveguide. These results demonstrate that dispersion engineering and parametric gain can be jointly exploited to tailor the spectral-mode structure of squeezed-light sources, enabling their optimization for a broad range of quantum applications.</jats:p>"}],"issue":"2","publication":"Physical Review A","user_id":"115260","volume":114,"publisher":"American Physical Society (APS)","_id":"67133","status":"public","citation":{"ieee":"J.

Within the collaborative project WerKo3D, the scaling, process qualification, and structural design of the novel tool steel Printium 13 were successfully investigated to lower market entry barriers for additive tooling applications. An industrial batch of 50 kg of Printium 13 powder was produced via vacuum inert gas atomization and thoroughly characterized. Utilizing a Design of Experiments (DoE) approach on an SLM 280 system, an optimized process window was established, yielding a relative density of about 99.99%. Subsequent heat treatment parameterizations revealed a superior mechanical property profile combining high hardness with enhanced impact toughness compared to conventional AISI H13 tool steel, alongside ultimate tensile strengths up to 1,600 MPa. To reduce build times and material consumption, a segmented shell-core tool design was conceptualized and numerically optimized via coupled CFD and FEM simulations. The functional demonstrator - a sprue insert for aluminum die casting - was additively manufactured without cracking, heat-treated, and finish-machined to final dimensions. Furthermore, a two-day training and knowledge-transfer program was realized to disseminate design guidelines to industry stakeholders.

Whereas most studies have focused on above-bandgap high-order harmonics, which are usually interpreted through short electron-hole trajectories that recombine within one optical cycle, the microscopic origin of low-order emission near the bandgap remains poorly understood. Here, we investigate near-bandgap harmonic generation in ZnO by combining semiconductor Bloch equations with a complex-time quantum-trajectory analysis.

Companies must comply with numerous regulations for such product approvals. This results in requirements for processes, methods, tools and organizations throughout the product life cycle. A proven approach to handling regulatory requirements is the application of product lifecycle management (PLM) platforms. Applying PLM platforms (e.g. Teamcenter, 3DExperience) poses challenges in designing compliant processes as well as adapting methods and tools. For example, in medical technology, ISO 13485 specifies an industry-specific product engineering process. The exemplary adaptations of requirements engineering methods and related support – e.g. MBSE including Requirements Diagrams – are not intuitively apparent. Existing literature primarily regards these regulation-related challenges as boundary conditions, offering only vague operational solutions. Companies struggle to align PLM processes with regulatory requirements, yet few methods exist to support this integration. In this paper, a method is proposed that supports the application of regulation-centered PLM platforms and reduces effort in product approvals. The method is developed by applying a five-step approach. Existing literature on process models for applying PLM platforms is identified (1). The identified approaches are then analyzed to determine whether and to what extent they consider regulations in applying PLM platforms (2). Based on identified partial solutions from literature and findings from industry workshops, a new method is developed (3). The method comprises strategic level, process level, data level, pilot level, and operation level. Validation is conducted within a German medical technology company, containing proof of applicability determined through a pilot project (4) and proof of concept achieved through interviews (5). The method is applied to regulation-centered PLM for the use case ‘requirements engineering’. The concept is confirmed by experts in terms of applicability and transferability. The method supports engineers in applying regulation-centered PLM platforms, leading to reduced effort."}],"language":[{"iso":"eng"}],"doi":"https://doi.org/10.1002/iis2.70264","author":[{"id":"47565","orcid":"0000-0001-5765-971X","first_name":"Iris","last_name":"Gräßler","full_name":"Gräßler, Iris"},{"last_name":"Pfeifer","first_name":"Jan Niklas","full_name":"Pfeifer, Jan Niklas","id":"62841"},{"last_name":"Trost","first_name":"Denis","full_name":"Trost, Denis"}],"publication_identifier":{"issn":["2334-5837"]},"year":"2026","title":"RegPLM – A method for the application of regulation-centered PLM platforms","intvolume":"        36","publication_status":"published","date_updated":"2026-09-18T08:56:11Z"},{"citation":{"apa":"Aßbrock, T., Sperling, J., &#38; Ares, L.

By confining the dynamics to the manifold of angular momentum coherent states, which act as the classical reference in this case, we compute the speed limit that bounds the rate of change of the state achievable without generating quantum coherence. A comparison with the unrestricted quantum speed limit enables the quantitative identification of speedups arising from polarization nonclassicality. We apply this framework to the cross-Kerr interaction, demonstrating a persistent speedup scaling as\r\n                    <a:math xmlns:a=\"http://www.w3.org/1998/Math/MathML\">\r\n                      <a:mrow>\r\n                        <a:mi mathvariant=\"script\">O</a:mi>\r\n                        <a:mo>(</a:mo>\r\n                        <a:msqrt>\r\n                          <a:mi>N</a:mi>\r\n                        </a:msqrt>\r\n                        <a:mo>)</a:mo>\r\n                      </a:mrow>\r\n                    </a:math>\r\n                    with the photon number\r\n                    <c:math xmlns:c=\"http://www.w3.org/1998/Math/MathML\">\r\n                      <c:mi>N</c:mi>\r\n                    </c:math>\r\n                    , with a parity effect in favor of even photon numbers.
