  abstract     = {{Diskriminierungserfahrungen können sich negativ auf die Kompetenzentwicklung von Schülerinnen und Schülern auswirken, was wiederum Bildungsungerechtigkeit zur Folge haben kann (Hummrich, 2023). Um solchen Dynamiken frühzeitig entgegenzuwirken soll in der Lehrkräfteausbildung, nach den Standards der Kultusministerkonferenz (KMK) auch der reflektierte Umgang mit Diskriminierung gefördert werden: „Die Absolventinnen und Absolventen […] analysieren Konflikte und kennen Methoden der konstruktiven Konfliktbearbeitung sowie des Umgangs mit Gewalt und Diskriminierung“ (KMK, 2019, S.10). Ein wichtiger Bestandteil der universitären Phase ist das Praxissemester (PS), das in NRW ein fünfmonatiges Schulpraktikum umfasst. Obwohl sich bereits einige Studien mit Diskriminierungserfahrungen an Schulen (z.B. Höhl, 2021; Ziemes, 2024) und in der Lehrkräfteausbildung (Fereidooni, 2015) auseinandersetzten, gibt es bislang keine quantitative Studie, die die Perspektive von Lehramtsstudierenden im PS systematisch einbezieht. An der Universität Paderborn wurde daher in einer explorativen Querschnittsbefragung (N=431) erfasst, inwiefern Lehramtsstudierende Diskriminierungssituationen im Praxissemester beobachten und wie sie ihre Kompetenzen im Umgang mit Diskriminierung in der Schule einschätzen. In den Ergebnissen zeigt sich, dass die Studierenden das Differenzmerkmal Migrationshintergrund mit 31% in den beobachteten Fällen als Diskriminierungsgrund nannten. Zudem nahmen sie wahr, dass am häufigsten die Schüler*innen untereinander abwertend über andere Mitschüler*innen sprachen. Dies kam bei 67% der Befragten mindestens einmal im PS vor. Bei den Studierenden selbst haben 11% mindestens einmal im PS Diskriminierung durch Lehrkräfte erfahren und mit 14% wurden sie mindestens einmal von Schüler*innen diskriminiert. Die Studierenden hielten sich aber überwiegend für ausreichend kompetent im Umgang mit Diskriminierungssituationen.}},

  abstract     = {{Lithium niobate (LiNbO3) is a widely used material with several desirable physical properties, such as high second-order nonlinear optical and strong electro-optical effects. Thus LiNbO3 is used for various applications such as electro-optic modulation or nonlinear frequency conversion and mixing. But LiNbO3 also exhibits a strong photorefractive effect, which limits the intensity of the optical fields involved. Various approaches to reduce the photorefractive effect have been investigated, such as increasing the temperature, doping the crystal or using different waveguide designs in LiNbO3. Here, we present an analysis of the approach to increase the photorefractive damage threshold by using different waveguide designs. Contrary to previous claims and investigations, our SHG measurements revealed no significant difference in resistance to photorefractive damage when comparing conventional Ti-doped channel waveguides and Ti-doped diced ridge waveguides in LiNbO3. Furthermore, we have investigated the effect of photorefractive cleaning and curing using a light field at 532 nm. Here, we observe a reduction in the photorefractive effect at room temperature during and after SHG measurements, which is an easy alternative to conventional approaches.}},

  abstract     = {{<jats:p>Quantum uncertainty relations impose fundamental limits on the joint knowledge that can be acquired from complementary observables: Perfect knowledge of a quantum state in one basis implies maximal indetermination in all other mutually unbiased bases (MUBs). Uncertainty relations derived from joint properties of the MUBs are generally assumed to be uniform, irrespective of the specific observables chosen within a set. In this work, we demonstrate instead that the uncertainty relations can depend on the choice of observables. Through both experimental observation and numerical methods, we show that selecting different sets of three MUBs in a five-dimensional quantum system results in distinct uncertainty bounds, i.e., in varying degrees of complementarity, in terms of both entropy and variance.</jats:p>}},

  abstract     = {{<jats:p>We study a possibility of measuring the time-resolved second-order autocorrelation function of one of two beams generated in type-II parametric down-conversion by means of temporal magnification of this beam, bringing its correlation time from the picosecond to the nanosecond scale, which can be resolved by modern photodetectors. We show that such a measurement enables one to infer directly the degree of global coherence of that beam, which is linked by a simple relation to the number of modes characterizing the entanglement between the two generated beams. We illustrate the proposed method by an example of photon pairs generated in a periodically poled potassium titanyl phosphate (KTP) crystal with a symmetric group velocity matching for various durations of the pump pulse, resulting in different numbers of modes. Our theoretical model also shows that the magnified double-heralded autocorrelation function of one beam exhibits a local maximum around zero delay time, corresponding to photon bunching at a short time scale.</jats:p>}},

               <jats:p>High-dimensional time-frequency encodings have the potential to significantly advance quantum information science; however, practical applications require precise knowledge of the encoded quantum states, which becomes increasingly challenging for larger Hilbert spaces. Self-guided tomography (SGT) has emerged as a practical and scalable technique for this purpose in the spatial domain. Here, we apply SGT to estimate time-frequency states using a multi-output quantum pulse gate. We achieve fidelities of more than 99% for 3- and 5-dimensional states without the need for calibration or post-processing. We demonstrate the robustness of SGT against statistical and environmental noise, highlighting its efficacy in the photon-starved regime typical of quantum information applications.</jats:p>}},
