  text: "<jats:p>\r\n                    Spins confined in optically active quantum
    dot molecules (QDMs) can be used for the deterministic generation of photonic
    graph states with tailored entanglement structures. Their usefulness for the generation
    of such nonclassical states of light is determined by orbital and spin decoherence
    mechanisms, particularly phonon-mediated processes dominant at energy scales up
    to a few millielectronvolts. Here, we directly measure the spectral function of
    orbital phonon relaxation between the energy states of the neutral exciton in
    a QDM and benchmark our findings against microscopic\r\n                    <a:math

    tunability of the exciton lifetime which can be leveraged to increase the lifetime
    of energetically unfavorable charge configurations needed for realizing efficient
    spin-photon interfaces and multidimensional cluster states.\r\n                  </jats:p>"

  text: "Despite the fundamental role the Quantum Satisfiability (QSAT) problem has\r\nplayed
    in quantum complexity theory, a central question remains open: At which\r\nlocal
    dimension does the complexity of QSAT transition from \"easy\" to \"hard\"?\r\nHere,
    we study QSAT with each constraint acting on a $k$-dimensional and\r\n$l$-dimensional
    qudit pair, denoted $(k,l)$-QSAT. Our first main result shows\r\nthat, surprisingly,
    QSAT on qubits can remain $\\mathsf{QMA}_1$-hard, in that\r\n$(2,5)$-QSAT is $\\mathsf{QMA}_1$-complete.
    In contrast, $2$-SAT on qubits is\r\nwell-known to be poly-time solvable [Bravyi,
    2006]. Our second main result\r\nproves that $(3,d)$-QSAT on the 1D line with
    $d\\in O(1)$ is also\r\n$\\mathsf{QMA}_1$-hard. Finally, we initiate the study
    of 1D $(2,d)$-QSAT by\r\ngiving a frustration-free 1D Hamiltonian with a unique,
    entangled ground state.\r\n  Our first result uses a direct embedding, combining
    a novel clock\r\nconstruction with the 2D circuit-to-Hamiltonian construction
    of [Gosset, Nagaj,\r\n2013]. Of note is a new simplified and analytic proof for
    the latter (as\r\nopposed to a partially numeric proof in [GN13]). This exploits
    Unitary Labelled\r\nGraphs [Bausch, Cubitt, Ozols, 2017] together with a new \"Nullspace
    Connection\r\nLemma\", allowing us to break low energy analyses into small patches
    of\r\nprojectors, and to improve the soundness analysis of [GN13] from\r\n$\\Omega(1/T^6)$
    to $\\Omega(1/T^2)$, for $T$ the number of gates. Our second\r\nresult goes via
    black-box reduction: Given an arbitrary 1D Hamiltonian $H$ on\r\n$d'$-dimensional
    qudits, we show how to embed it into an effective null-space\r\nof a 1D $(3,d)$-QSAT
    instance, for $d\\in O(1)$. Our approach may be viewed as a\r\nweaker notion of
    \"simulation\" (\\`a la [Bravyi, Hastings 2017], [Cubitt,\r\nMontanaro, Piddock
    2018]). As far as we are aware, this gives the first\r\n\"black-box simulation\"-based
    $\\mathsf{QMA}_1$-hardness result, i.e. for\r\nfrustration-free Hamiltonians."

  text: "Estimating ground state energies of many-body Hamiltonians is a central task\r\nin
    many areas of quantum physics. In this work, we give quantum algorithms\r\nwhich,
    given any $k$-body Hamiltonian $H$, compute an estimate for the ground\r\nstate
    energy and prepare a quantum state achieving said energy, respectively.\r\nSpecifically,
    for any $\\varepsilon>0$, our algorithms return, with high\r\nprobability, an
    estimate of the ground state energy of $H$ within additive\r\nerror $\\varepsilon
    M$, or a quantum state with the corresponding energy. Here,\r\n$M$ is the total
    strength of all interaction terms, which in general is\r\nextensive in the system
    size. Our approach makes no assumptions about the\r\ngeometry or spatial locality
    of interaction terms of the input Hamiltonian and\r\nthus handles even long-range
    or all-to-all interactions, such as in quantum\r\nchemistry, where lattice-based
    techniques break down. In this fully general\r\nsetting, the runtime of our algorithms
    scales as $2^{cn/2}$ for $c<1$, yielding\r\nthe first quantum algorithms for low-energy
    estimation breaking the natural\r\nbound based on Grover search. The core of our
    approach is remarkably simple,\r\nand relies on showing that any $k$-body Hamiltonian
    has a low-energy subspace\r\nof exponential dimension."

  text: "We investigate the role of energy, i.e. average photon number, as a resource\r\nin
    the computational complexity of bosonic systems. We show three sets of\r\nresults:
    (1. Energy growth rates) There exist bosonic gate sets which increase\r\nenergy
    incredibly rapidly, obtaining e.g. infinite energy in finite/constant\r\ntime.
    We prove these high energies can make computing properties of bosonic\r\ncomputations,
    such as deciding whether a given computation will attain infinite\r\nenergy, extremely
    difficult, formally undecidable. (2. Lower bounds on\r\ncomputational power) More
    energy ``='' more computational power. For example,\r\ncertain gate sets allow
    poly-time bosonic computations to simulate PTOWER, the\r\nset of deterministic
    computations whose runtime scales as a tower of\r\nexponentials with polynomial
    height. Even just exponential energy and $O(1)$\r\nmodes suffice to simulate NP,
    which, importantly, is a setup similar to that of\r\nthe recent bosonic factoring
    algorithm of [Brenner, Caha, Coiteux-Roy and\r\nKoenig (2024)]. For simpler gate
    sets, we show an energy hierarchy theorem. (3.\r\nUpper bounds on computational
    power) Bosonic computations with polynomial\r\nenergy can be simulated in BQP,
    ``physical'' bosonic computations with\r\narbitrary finite energy are decidable,
    and the gate set consisting of Gaussian\r\ngates and the cubic phase gate can
    be simulated in PP, with exponential bound\r\non energy, improving upon the previous
    PSPACE upper bound. Finally, combining\r\nupper and lower bounds yields no-go
    theorems for a continuous-variable\r\nSolovay--Kitaev theorem for gate sets such
    as the Gaussian and cubic phase\r\ngates."

  text: "The Quantum k-SAT problem is the quantum generalization of the k-SAT problem.\r\nIt
    is the problem whether a given local Hamiltonian is frustration-free.\r\nFrustration-free
    means that the ground state of the k-local Hamiltonian\r\nminimizes the energy
    of every local interaction term simultaneously. This is a\r\ncentral question
    in quantum physics and a canonical QMA_1-complete problem. The\r\nQuantum k-SAT
    problem is not as well studied as the classical k-SAT problem in\r\nterms of special
    tractable cases, approximation algorithms and parameterized\r\ncomplexity. In
    this paper, we will give a graph-theoretic study of the Quantum\r\nk-SAT problem
    with the structures core and radius. These hypergraph structures\r\nare important
    to solve the Quantum k-SAT problem. We can solve a Quantum k-SAT\r\ninstance in
    polynomial time if the derived hypergraph has a core of size n-m+a,\r\nwhere a
    is a constant, and the radius is at most logarithmic. If it exists, we\r\ncan
    find a core of size n-m+a with the best possible radius in polynomial time,\r\nwhereas
    finding a general minimum core with minimal radius is NP-hard."

  text: <jats:p>Local droplet etching and subsequent refilling enables the fabrication
    of highly symmetric quantum dots with low fine structure splitting, suitable for
    generating polarization entangled photons. While well established in GaAs/AlxGa1−xAs,
    this approach does not yield emission in the telecom bands required for low loss
    fiber-based quantum communication. To achieve emission at 1.55 μm, local droplet
    etching must be adapted to alternative material platforms such as InP. Here, we
    systematically investigate how the etching material deposition rate and etching
    time influence nanohole morphology in In0.52Al0.48As layers lattice-matched to
    InP. In the first experiment, InAl was deposited at fluxes of 0.2–4.0 Å s−1 at
    Tetch = 350 °C and 460 °C. Lower fluxes produced nanoholes with lower density
    and larger ring diameters, indicating fewer and larger initial droplets, consistent
    with scaling theory. The average nanohole diameter decreased monotonically with
    increasing flux, whereas the average depth showed no clear dependence on flux.
    In the second experiment, etching times of 30–600 s were tested for InAl, In,
    and Al droplets. Average nanohole diameters remained constant for Al across all
    etching times, but decreased for In and InAl with increasing etching time, suggesting
    sidewall redeposition during etching. For all droplet types, depths peaked at
    intermediate times and decreased for prolonged etching, consistent with material
    diffusion into the nanohole after droplet consumption.</jats:p>

  text: This study examines how strengthening tax enforcement by increasing human
    enforcement capacity and improving tax audit technology affect tax audit efficiency.
    I employ an economic model in which a tax manager’s tax planning effort shapes
    corporate tax planning and a strategic tax auditor makes a technology-based audit
    decision. I show that strengthening tax enforcement always increases tax revenues,
    but decreases the number of audits only under narrow conditions, so that its effect
    on tax audit efficiency is often ambiguous. Improving tax audit technology has
    more nuanced implications. When the strength of tax enforcement is sufficiently
    high, gradual improvements in tax audit technology crowd out audit incentives
    and, surprisingly, reduce tax revenues, while sufficiently large improvements
    can overturn this adverse revenue effect. At the same time, improved technology
    lowers unnecessary audits once the strength of tax enforcement exceeds a minimum
    level. Therefore, sufficiently large technology improvements improve tax audit
    efficiency once this minimum level is exceeded. The results have important policy
    and empirical implications in an environment of constrained fiscal budgets and
    rapidly advancing audit technologies.

  text: This study analyzes the impact of tariff imposition announcements on the stock
    prices of 1,194 U.S. companies during the first Trump administration, using a
    unique sample of 4,624 announcements made by or against the U.S. between January
    2018 and August 2019. We find that tariff announcements lead to negative (cumulative)
    average abnormal stock returns. These negative wealth effects occur regardless
    of whether the Trump administration imposes safeguard tariffs to protect domestic
    industries or foreign countries announce retaliatory tariffs. Moreover, the adverse
    impact is primarily driven by announcements involving China, with variations linked
    to sector-specific, tariff, trade, and firm characteristics.

  text: <jats:p>Abstract. Saving emissions and a circular economy are key aspects
    of sustainable production and compliance global climate change targets. Friction-induced
    solid-state recycling of aluminum scrap to production endless semi-finished products.
    Scrap is fed into a continuously rotating wheel. This requires less energy compared
    to heat-based recycling processes. Different sizes, shapes and surfaces of chips
    can be used as starting material in the process. The influence of this has been
    shown in past publications. A native oxide layer is a fixed component of aluminum
    surface. This layer is broken up during the forming process, allowing the aluminum
    to bond. In addition to the geometry, the surface finishes and the thickness of
    the oxide layer are therefore also important input variables in friction-induced
    solid-state recycling. The oxide layers on the chips were determined for the investigation.
    In addition, different layer thicknesses were produced to survey their influence.
    The resulting semi-finished products were evaluated on the basis of their tensile
    strength and microstructure. The main result of the investigations is the fact
    that semi-finished products made from chips with thicker oxide layers tend to
    be more brittle. In addition, thick oxide layers cause microstructural and surface
    defects.</jats:p>
