  text: <jats:p>We theoretically investigate strategies for the deterministic creation
    of trains of time-bin entangled photons using an individual quantum emitter described
    by a Λ-type electronic system. We explicitly demonstrate the theoretical generation
    of linear cluster states with substantial numbers of entangled photonic qubits
    in full microscopic numerical simulations. The underlying scheme is based on the
    manipulation of ground state coherences through precise optical driving. One important
    finding is that the most easily accessible quality metrics, the achievable rotation
    fidelities, fall short in assessing the actual quantum correlations of the emitted
    photons in the face of losses. To address this, we explicitly calculate stabilizer
    generator expectation values as a superior gauge for the quantum properties of
    the generated many-photon state. With widespread applicability in other emitter
    and excitation–emission schemes also, our work lays the conceptual foundations
    for an in-depth practical analysis of time-bin entanglement based on full numerical
    simulations with predictive capabilities for realistic systems and setups, including
    losses and imperfections. The specific results shown in the present work illustrate
    that with controlled minimization of losses and realistic system parameters for
    quantum-dot type systems, useful linear cluster states of significant lengths
    can be generated in the calculations, discussing the possibility of scalability
    for quantum information processing endeavors.</jats:p>

    A mechanism for the adsorption of PVAc at the two electrolyte/substrate interfaces

  text: At large scales, quantum systems may become advantageous over their classical
    counterparts at performing certain tasks. Developing tools to analyze these systems
    at the relevant scales, in a manner consistent with quantum mechanics, is therefore
    critical to benchmarking performance and characterizing their operation. While
    classical computational approaches cannot perform like-for-like computations of
    quantum systems beyond a certain scale, classical high-performance computing (HPC)
    may nevertheless be useful for precisely these characterization and certification
    tasks. By developing open-source customized algorithms using high-performance
    computing, we perform quantum tomography on a megascale quantum photonic detector
    covering a Hilbert space of 106. This requires finding 108 elements of the matrix
    corresponding to the positive operator valued measure (POVM), the quantum description
    of the detector, and is achieved in minutes of computation time. Moreover, by
    exploiting the structure of the problem, we achieve highly efficient parallel
    scaling, paving the way for quantum objects up to a system size of 1012 elements
    to be reconstructed using this method. In general, this shows that a consistent
    quantum mechanical description of quantum phenomena is applicable at everyday
    scales. More concretely, this enables the reconstruction of large-scale quantum
    sources, processes and detectors used in computation and sampling tasks, which
    may be necessary to prove their nonclassical character or quantum computational
    advantage.

  text: Residual stresses in directly joined laminates made of steel and carbon fiber
    reinforced epoxy resin reduce the interface and bond strength and thus have to
    be taken into account for the strength analysis of structural components. For
    a holistic description of residual stresses, a thermo-chemo-mechanical constitutive
    model is introduced in the present work and presented for the multi-scale analysis
    of residual stress patterns. In this context, the analysis of representative unit
    cells with regular and stochastic distribution of fibers gives information about
    the associated deformation and stress fields. Dehomogenization at macroscopically
    highly stressed regions, characterized by local stress peaks, reveals the effect
    of gradient deformation in the microstructure. Another aspect of this work is
    the development of FFT-based Galerkin methods, which allows an evaluation of the
    effect of defect densities, heterogeneities and morphologies on the applicability
    of the incremental hole drilling method. It could be demonstrated that the incremental
    hole drilling method is particularly sensitive to defects running along the surface.

  text: Eigenspannungen in direktgefügten Werkstoffverbunden aus Stahl und kohlenstofffaserverstärktem
    Epoxidharz reduzieren die Grenzschicht- und Verbundfestigkeit und sind somit für
    die Festigkeitsbeurteilung von Strukturen zwingend zu berücksichtigen. Zur ganzheitlichen
    Beschreibung von Eigenspannungen wird in der vorliegenden Arbeit ein thermo-chemo-mechanisches
    Konstitutivmodell für die skalenübergreifende Bewertung von Eigenspannungsverteilungen
    vorgestellt. Die Analyse von repräsentativen Einheitszellen mit regulärer und
    stochastischer Verteilung von Fasern liefert in diesem Zusammenhang Informationen
    über die zugehörigen Deformations- und Spannungsfelder. Die Dehomogenisierung
    an makroskopisch hochbelasteten Bereichen, die durch lokale Spannungsüberhöhungen
    gekennzeichnet sind, zeigt die Auswirkung der gradientenbehafteten Deformation
    in der Mikrostruktur. Ein weiterer Aspekt dieser Arbeit ist die Entwicklung FFT-basierter
    Galerkin-Methoden, die es erstmalig erlauben, eine Bewertung der Auswirkung von
    Defektdichte, Heterogenität und Morphologie auf die Anwendbarkeit der inkrementellen
    Bohrlochmethode vorzunehmen. Es konnte nachgewiesen werden, dass die inkrementelle
    Bohrlochmethode insbesondere auf an der Oberfläche verlaufende Defekte sensitiv
    reagiert.

  text: "As in almost every other branch of science, the major advances in data\r\nscience
    and machine learning have also resulted in significant improvements\r\nregarding
    the modeling and simulation of nonlinear dynamical systems. It is\r\nnowadays
    possible to make accurate medium to long-term predictions of highly\r\ncomplex
    systems such as the weather, the dynamics within a nuclear fusion\r\nreactor,
    of disease models or the stock market in a very efficient manner. In\r\nmany cases,
    predictive methods are advertised to ultimately be useful for\r\ncontrol, as the
    control of high-dimensional nonlinear systems is an engineering\r\ngrand challenge
    with huge potential in areas such as clean and efficient energy\r\nproduction,
    or the development of advanced medical devices. However, the\r\nquestion of how
    to use a predictive model for control is often left unanswered\r\ndue to the associated
    challenges, namely a significantly higher system\r\ncomplexity, the requirement
    of much larger data sets and an increased and often\r\nproblem-specific modeling
    effort. To solve these issues, we present a universal\r\nframework (which we call
    QuaSiModO:\r\nQuantization-Simulation-Modeling-Optimization) to transform arbitrary\r\npredictive
    models into control systems and use them for feedback control. The\r\nadvantages
    of our approach are a linear increase in data requirements with\r\nrespect to
    the control dimension, performance guarantees that rely exclusively\r\non the
    accuracy of the predictive model, and only little prior knowledge\r\nrequirements
    in control theory to solve complex control problems. In particular\r\nthe latter
    point is of key importance to enable a large number of researchers\r\nand practitioners
    to exploit the ever increasing capabilities of predictive\r\nmodels for control
    in a straight-forward and systematic fashion."

  text: "Continuous Speech Separation (CSS) has been proposed to address speech overlaps
    during the analysis of realistic meeting-like conversations by eliminating any
    overlaps before further processing.\r\nCSS separates a recording of arbitrarily
    many speakers into a small number of overlap-free output channels, where each
    output channel may contain speech of multiple speakers.\r\nThis is often done
    by applying a conventional separation model trained with Utterance-level Permutation
    Invariant Training (uPIT), which exclusively maps a speaker to an output channel,
    in sliding window approach called stitching.\r\nRecently, we introduced an alternative
    training scheme called Graph-PIT that teaches the separation network to directly
    produce output streams in the required format without stitching.\r\nIt can handle
    an arbitrary number of speakers as long as never more of them overlap at the same
    time than the separator has output channels.\r\nIn this contribution, we further
    investigate the Graph-PIT training scheme.\r\nWe show in extended experiments
    that models trained with Graph-PIT also work in challenging reverberant conditions.\r\nModels
    trained in this way are able to perform segment-less CSS, i.e., without stitching,
    and achieve comparable and often better separation quality than the conventional
    CSS with uPIT and stitching.\r\nWe simplify the training schedule for Graph-PIT
    with the recently proposed Source Aggregated Signal-to-Distortion Ratio (SA-SDR)
    loss.\r\nIt eliminates unfavorable properties of the previously used A-SDR loss
    and thus enables training with Graph-PIT from scratch.\r\nGraph-PIT training relaxes
    the constraints w.r.t. the allowed numbers of speakers and speaking patterns which
    allows using a larger variety of training data.\r\nFurthermore, we introduce novel
    signal-level evaluation metrics for meeting scenarios, namely the source-aggregated
    scale- and convolution-invariant Signal-to-Distortion Ratio (SA-SI-SDR and SA-CI-SDR),
    which are generalizations of the commonly used SDR-based metrics for the CSS case."

  text: <jats:title>Abstract</jats:title><jats:p>The biexciton‐exciton emission cascade
    commonly used in quantum‐dot systems to generate polarization entanglement yields
    photons with intrinsically limited indistinguishability. In the present work,
    it focuses on the generation of pairs of photons with high degrees of polarization
    entanglement and simultaneously high indistinguishability. It achieves this goal
    by selectively reducing the biexciton lifetime with an optical resonator. It demonstrates
    that a suitably tailored circular Bragg reflector fulfills the requirements of
    sufficient selective Purcell enhancement of biexciton emission paired with spectrally
    broad photon extraction and twofold degenerate optical modes. The in‐depth theoretical
    study combines (i) the optimization of realistic photonic structures solving Maxwell's
    equations from which model parameters are extracted as input for (ii) microscopic
    simulations of quantum‐dot cavity excitation dynamics with full access to photon
    properties. It reports non‐trivial dependencies on system parameters and use the
    predictive power of the combined theoretical approach to determine the optimal
    range of Purcell enhancement that maximizes indistinguishability and entanglement
    to near unity values, here specifically for the telecom C‐band at 1550 nm.</jats:p>

  text: The biexciton-exciton emission cascade commonly used in quantum-dot systems
    to generate polarization entanglement yields photons with intrinsically limited
    indistinguishability. In the present work we focus on the generation of pairs
    of photons with high degrees of polarization entanglement and simultaneously high
    indistinguishibility. We achieve this goal by selectively reducing the biexciton
    lifetime with an optical resonator. We demonstrate that a suitably tailored circular
    Bragg reflector fulfills the requirements of sufficient selective Purcell enhancement
    of biexciton emission paired with spectrally broad photon extraction and two-fold
    degenerate optical modes. Our in-depth theoretical study combines (i) the optimization
    of realistic photonic structures solving Maxwell's equations from which model
    parameters are extracted as input for (ii) microscopic simulations of quantum-dot
    cavity excitation dynamics with full access to photon properties. We report non-trivial
    dependencies on system parameters and use the predictive power of our combined
    theoretical approach to determine the optimal range of Purcell enhancement that
    maximizes indistinguishability and entanglement to near unity values in the telecom
    C-band at $1550\,\mathrm{nm}$.

  text: "Viscous hydrodynamics serves as a successful mesoscopic description of the\r\nQuark-Gluon
    Plasma produced in relativistic heavy-ion collisions. In order to\r\ninvestigate,
    how such an effective description emerges from the underlying\r\nmicroscopic dynamics
    we calculate the hydrodynamic and non-hydrodynamic modes\r\nof linear response
    in the sound channel from a first-principle calculation in\r\nkinetic theory.
    We do this with a new approach wherein we discretize the\r\ncollision kernel to
    directly calculate eigenvalues and eigenmodes of the\r\nevolution operator. This
    allows us to study the Green's functions at any point\r\nin the complex frequency
    space. Our study focuses on scalar theory with quartic\r\ninteraction and we find
    that the analytic structure of Green's functions in the\r\ncomplex plane is far
    more complicated than just poles or cuts which is a first\r\nstep towards an equivalent
    study in QCD kinetic theory."

  text: "Memory Gym presents a suite of 2D partially observable environments, namely\r\nMortar
    Mayhem, Mystery Path, and Searing Spotlights, designed to benchmark\r\nmemory
    capabilities in decision-making agents. These environments, originally\r\nwith
    finite tasks, are expanded into innovative, endless formats, mirroring the\r\nescalating
    challenges of cumulative memory games such as ``I packed my bag''.\r\nThis progression
    in task design shifts the focus from merely assessing sample\r\nefficiency to
    also probing the levels of memory effectiveness in dynamic,\r\nprolonged scenarios.
    To address the gap in available memory-based Deep\r\nReinforcement Learning baselines,
    we introduce an implementation that\r\nintegrates Transformer-XL (TrXL) with Proximal
    Policy Optimization. This\r\napproach utilizes TrXL as a form of episodic memory,
    employing a sliding window\r\ntechnique. Our comparative study between the Gated
    Recurrent Unit (GRU) and\r\nTrXL reveals varied performances across different
    settings. TrXL, on the finite\r\nenvironments, demonstrates superior sample efficiency
    in Mystery Path and\r\noutperforms in Mortar Mayhem. However, GRU is more efficient
    on Searing\r\nSpotlights. Most notably, in all endless tasks, GRU makes a remarkable\r\nresurgence,
    consistently outperforming TrXL by significant margins. Website and\r\nSource

  text: "Many materials processes and properties depend on the anisotropy of the\r\nenergy
    of grain boundaries, i.e.~on the fact that this energy is a function of\r\nthe
    five geometric degrees of freedom (DOF) of the interface. To access this\r\nparameter
    space in an efficient way and to discover energy cusps in unexplored\r\nregions,
    a method was recently established, which combines atomistic\r\nsimulations with
    statistical methods 10.1002/adts.202100615. This sequential\r\nsampling technique
    is now extended in the spirit of an active learning\r\nalgorithm by adding a criterion
    to decide when the sampling has advanced enough\r\nto stop. In this instance,
    two parameters to analyse the sampling results on\r\nthe fly are introduced: the
    number of cusps, which correspond to the most\r\ninteresting and important regions
    of the energy landscape, and the maximum\r\nchange of energy between two sequential
    iterations. Monitoring these two\r\nquantities provides valuable insight into
    how the subspaces are energetically\r\nstructured. The combination of both parameters
    provides the necessary\r\ninformation to evaluate the sampling of the 2D subspaces
    of grain boundary\r\nplane inclinations of even non-periodic, low angle grain
    boundaries. With a\r\nreasonable number of data points in the initial design,
    only a few\r\nappropriately chosen sequential iterations already improve the accuracy
    of the\r\nsampling substantially and unknown cusps can be found within a few additional\r\nsequential
    steps."
