text: Simulating vibronic spectra is a central task in physical chemistry, offering
insight into important properties of molecules. 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.

text: "After nearly two decades of research, the question of a quantum PCP theorem\r\nfor
quantum Constraint Satisfaction Problems (CSPs) remains wide open. 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]."

text: 'Scalable plasmonic technologies face a critical trade‐off: few‐body architectures
offer high enhancement but are sensitive to fabrication flaws, while scalable
methods like solid‐state dewetting yield large, low‐enhancement gaps. 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.'

text: We introduce a method for determining the sensitivity of any given entangled
two-photon absorption (ETPA) measurement. By modeling all signal and noise contributions
to the measurement, we derive a single numerical value that describes the sensitivity
of the ETPA measurement in Göppert-Mayer units. This allows us to directly compare
vastly different experimental approaches and determine whether ETPA will be detectable
under the given conditions. Therefore we can quantify the effect of any change
to a given experimental apparatus and identify the ideal optimization pathway.

text: "\r\n We develop a framework for identifying nonclassical
speedups in systems with polarization, likewise spin degrees of freedom. 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 \r\n
\ \r\n O\r\n
\ (\r\n \r\n
\ N\r\n \r\n
\ )\r\n \r\n
\ \r\n with the photon number\r\n
\ \r\n
\ N\r\n \r\n ,
with a parity effect in favor of even photon numbers. The results establish polarization
nonclassicality as a genuine dynamical resource, linking quantum coherence to
quantum-enhanced evolution speeds in nonlinear photonic systems.\r\n "

text: "Abstract\r\n The service
life of fatigue-loaded components that already contain manufacturing‑induced microcracks
is primarily governed by the direction and the rate of fatigue-crack growth. When
multiple loading components (e.g., tension, compression, shear) act simultaneously
but not in temporal synchrony, out‑of‑phase mixed‑mode conditions occur. Such
loadings are typical for automotive chassis parts and mechanically joined sheet‑metal
assemblies. For optimized design of structural components, the crack kinking angle
that occurs under mixed‑mode loading must be predicted as accurately as possible.
At present, however, this is still challenging for out‑of‑phase loading conditions.
To investigate the associated crack kinking behavior, a novel Compact‑Tension‑Shear‑Mini
(CTSM) specimen was developed, enabling controlled generation of plane out-of-phase
mixed-mode loading states. Experiments were performed under various combinations
of cyclic and static mode I and mode II load components and compared with the
analytical predictions of the Out-of-Phase Mixed-Mode (OMM) concept. The measured
crack kinking angles showed very good agreement with the predicted values, with
mean deviations of only a few degrees, demonstrating the validity and reproducibility
of the approach. These findings confirm the applicability of the OMM concept for
describing fatigue‑crack propagation under non‑proportional mixed‑mode loading
and provide a basis for fatigue‑life assessment of clinched joints and other cyclic
multi-axially loaded components."

text: Investigating crack growth in sheet metal originating from clinched
joints is a major part of predicting the service life of mechanically joined structures.
Clinching allows different materials to be joined together. A key task in this
context is to perform crack growth simulations in the vicinity of clinched joints
considering different load and environmental conditions. This requires formulaic
descriptions of the fatigue crack growth rate curves for the materials used. For
this purpose, fatigue crack growth rate curves for different R-ratios and temperatures
are determined experimentally. Generally, these fatigue crack growth rate curves
can be described very well using a novel two-part exponential approach for the
formulaic description of fatigue crack growth rate curves developed at Applied
Mechanics of Paderborn University (FAM). In this case, three parameters are sufficient
to describe the fatigue crack growth rate curves. For the material HCT590X, which
is frequently used in clinched joints, it is shown as an example how the parameters
vary with the R-ratio and the temperature. In addition, at high crack growth rates,
a significant rise in the fatigue crack growth rate curve sometimes occurs at
both low and high temperatures. To account for this feature, the two-part exponential
approach can be expanded to include a third part.

study theoretically how high-gain effects affect the measurement outcome of visible
signal spectra in undetected photon measurement schemes. We consider two interferometric
configurations: firstly, the SU(1,1) interferometer where the idler incurs loss
and additional dispersion in between two identical, lossless, squeezers; secondly,
the induced coherence interferometer where the idler incurs loss and additional
dispersion in between two identical, lossless, squeezers and where the second
squeezer is seeded by the idler and a vacuum ancilla mode. Furthermore, we consider
a distributed loss configuration where the idler incurs loss as it propagates
in the nonlinear medium. Motivated by experimental evidence and due to the fact
that broadband sources are ideal for these measurement schemes, we use the dispersive
data of a third-order dispersion engineered integrated waveguide parametric down
conversion (PDC) source presented in Roeder\r\n et
al\r\n (2024 New J. Phys.\r\n 26\r\n
\ 123025) to model the PDC spectra in the three configurations.
For each configuration we consider the case of idler-only (i) absorption, (ii)
additional dispersion, and (iii) the combined effects. We obtain results which
outline the strength and weaknesses of the different configurations at different
operation points.\r\n "

theoretically compare the quantum Fisher information (QFI) for three configurations
of absorption spectroscopy with undetected idler photons: an SU(1,1) interferometer
with inter-source idler loss, an induced-coherence (IC) setup in which the idler
partially seeds a second squeezer together with a vacuum ancilla, and a distributed-loss
(DL) scheme with in-medium attenuation. 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

text: The two-qubit controlled-not (C-NOT) gate is an essential component for gate-based
quantum circuits. In fact, its operation, combined with single qubit rotations
allows to realise any quantum circuit. Several strategies have been adopted in
order to build quantum gates. Among them, photonics offers the dual advantage
of excellent isolation from the environment and ease of manipulation at the single
qubit level. Here we adopt a scalable time-multiplexed approach in order to build
a fully reconfigurable architecture capable of implementing a post-selected C-NOT
gate with a fidelity of (93.8 ± 1.4)%. We then show how our time-multiplexed platform
can be employed to combine a C-NOT and a single qubit gate in order to generate
the four Bell states.

text: "Classical shadows are succinct classical representations of quantum states\r\nwhich
allow one to encode a set of properties P of a quantum state rho, while\r\nonly
requiring measurements on logarithmically many copies of rho in the size\r\nof
P. In this work, we initiate the study of verification of classical shadows,\r\ndenoted
classical shadow validity (CSV), from the perspective of computational\r\ncomplexity,
which asks: Given a classical shadow S, how hard is it to verify\r\nthat S predicts
the measurement statistics of a quantum state? We show that\r\neven for the elegantly
simple classical shadow protocol of [Huang, Kueng,\r\nPreskill, Nature Physics
2020] utilizing local Clifford measurements, CSV is\r\nQMA-complete. This hardness
continues to hold for the high-dimensional\r\nextension of said protocol due to
[Mao, Yi, and Zhu, PRL 2025]. Among other\r\nresults, we also show that CSV for
exponentially many observables is complete\r\nfor a quantum generalization of
the second level of the polynomial hierarchy,\r\nyielding the first natural complete
problem for such a class."

text: Three‐dimensional (3D) assemblies of gold nanoparticles (AuNPs) offer a rich
platform for plasmonic coupling and near‐field engineering, yet their optical
behavior is often complex due to structural disorder and fabrication‐induced variability.
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. These results provide process‐enabled guidelines
for using meniscus‐guided 3D‐nanoprinting to realize robust nanoparticle assemblies.

text: Multimode quantum light has promising applications in many areas of physics,
such as quantum communications and quantum computing. 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.

text: In increasingly volatile and uncertain markets, corporate resilience has become
a critical capability in strategic product planning. Companies face significant
challenges in systematically monitoring and interpreting heterogeneous environmental
data originating from diverse sources, formats, and temporal contexts. While predefined
workflows and decision trees can support strategic analysis, they often lack the
flexibility required to cope with dynamic market conditions and foresightrelated
data from extreme dispersed and heterogeneous sources. This paper proposes a method
to enhance corporate resilience through the application of generic, reusable AI-based
workflows in strategic product planning. The approach integrates Data Science
and Artificial Intelligence methods into modular, visually modelled workflows
that enable hybrid human-AI decision-making. Based on a systematic literature
review and an analysis of industrial challenges, key success factors and resilience
criteria are identified. These insights are used to develop a method that supports
internal and external analyses, scenario-based strategy development, and adaptive
implementation monitoring within a generic workflow structure. The method leverages
techniques such as machine learning and generative AI to process structured and
unstructured data, identify patterns, and support real-time strategic assessments.
Validation with decision-makers from medium-sized companies demonstrates improved
transparency, repeatability, and cross-functional collaboration compared to predefined
workflows.
