text: 'We review our results of numerical simulations of light scattering from different
systems of densely packed irregular particles. We consider spherical clusters,
thick layers and monolayers with realistic topologies and dimensions much larger
than the wavelength of light. The maximum bulk packing density of clusters is
0.5. A numerically exact solution of the electromagnetic problem is obtained using
the Discontinuous Galerkin Time Domain method and with application of high- performance
computing. We show that high packing density causes light localization in such
structures which makes an impact on the opposition phenomena: backscattering intensity
surge and negative linear polarization feature. Diffuse multiple scattering is
significantly reduced in the case of non-absorbing particles and near-field interaction
results in a percolation-like light transport determined by the topology of the
medium. With this the negative polarization feature caused by single scattering
gets enhanced if compared to lower density samples. We also confirm coherent double
scattering mechanism of negative polarization for light scattered from dense absorbing
slabs. In this case convergent result for the scattering angle polarization dependency
at backscattering can be obtained for a layer of just a few tens of particles
if they are larger than the wavelength.'

text: Transformation of Fe- and Cu-rich primary phase particles was studied in an
Al-Li-based alloy prepared by twin-roll casting. Thin foils for combined STEM
and SEM experiments were prepared by electrolytic twin-jet polishing. They were
in-situ heated in a TEM heating stage and observed at 200 kV in the JEOL JEM 2200FS
electron microscope equipped with STEM HAADF and BF detectors and SEM BSE and
SE detectors working both in composition and topographic modes. The resulting
structures were combined with EDS mapping performed directly in the heating holder.
Dissolution and transformation of Cu- and Fe-rich particles occur above 500 °C.
EDS maps acquired on the foil cooled down to room temperature show that Cu and
Fe are both still present in newly formed particles, most likely indicating the
presence of the Al7Cu2Fe phase.

text: "Abstract\r\n We demonstrate
the fabrication of micron-wide tungsten silicide superconducting nanowire single-photon
detectors on a silicon substrate using laser lithography. We show saturated internal
detection efficiencies with wire widths ranging from 0.59 µm
to 1.43 µm under illumination at 1550 nm. We demonstrate
both straight wires, as well as meandered structures. Single-photon sensitivity
is shown in devices up to 4 mm in length. Laser-lithographically written devices
allow for fast and easy structuring of large areas while maintaining a saturated
internal efficiency for wire widths around 1 µm."

text: "Abstract\r\n Lithium niobate
is a promising platform for integrated quantum optics. In this platform, we aim
to efficiently manipulate and detect quantum states by combining superconducting
single photon detectors and modulators. The cryogenic operation of a superconducting
single photon detector dictates the optimisation of the electro-optic modulators
under the same operating conditions. To that end, we characterise a phase modulator,
directional coupler, and polarisation converter at both ambient and cryogenic
temperatures. The operation voltage \r\n \r\n \r\n \r\n V\r\n

\ \r\n /\r\n
\ \r\n 2\r\n
\ \r\n \r\n
\ \r\n \r\n of these
modulators increases, due to the decrease in the electro-optic effect, by 74%
for the phase modulator, 84% for the directional coupler and 35% for the polarisation
converter below 8.5\r\n \r\n \r\n \r\n K\r\n \r\n \r\n
\ \r\n .
The phase modulator preserves its broadband nature and modulates light in the
characterised wavelength range. The unbiased bar state of the directional coupler
changed by a wavelength shift of 85\r\n \r\n \r\n \r\n n\r\n m\r\n

the device down to 5\r\n \r\n \r\n \r\n K\r\n \r\n \r\n

The polarisation converter uses periodic poling to phasematch the two orthogonal
polarisations. The phasematched wavelength of the utilised poling changes by 112\r\n

text: Superconducting Nanowire Single Photon Detectors (SNSPDs) have become
an integral part of quantum optics in recent years because of their high performance
in single photon detection. We present a method to replace the electrical input
by supplying the required bias current via the photocurrent of a photodiode situated
on the cold stage of the cryostat. Light is guided to the bias photodiode through
an optical fiber, which enables a lower thermal conduction and galvanic isolation
between room temperature and the cold stage. We show that an off-the-shelf InGaAs–InP
photodiode exhibits a responsivity of at least 0.55 A/W at 0.8 K. Using this device
to bias an SNSPD, we characterize the count rate dependent on the optical power
incident on the photodiode. This configuration of the SNSPD and photodiode shows
an expected plateau in the single photon count rate with an optical bias power
on the photodiode above 6.8 µW. Furthermore, we compare the same detector under
both optical and electrical bias, and show there is no significant changes in
performance. This has the advantage of avoiding an electrical input cable, which
reduces the latent heat load by a factor of 100 and, in principle, allows for
low loss RF current supply at the cold stage.

text: "The Quantum Singular Value Transformation (QSVT) is a recent technique that\r\ngives
a unified framework to describe most quantum algorithms discovered so\r\nfar,
and may lead to the development of novel quantum algorithms. In this paper\r\nwe
investigate the hardness of classically simulating the QSVT. A recent result\r\nby
Chia, Gily\\'en, Li, Lin, Tang and Wang (STOC 2020) showed that the QSVT can\r\nbe
efficiently \"dequantized\" for low-rank matrices, and discussed its\r\nimplication
to quantum machine learning. In this work, motivated by\r\nestablishing the superiority
of quantum algorithms for quantum chemistry and\r\nmaking progress on the quantum
PCP conjecture, we focus on the other main class\r\nof matrices considered in
applications of the QSVT, sparse matrices.\r\n We first show how to efficiently
\"dequantize\", with arbitrarily small\r\nconstant precision, the QSVT associated
with a low-degree polynomial. We apply\r\nthis technique to design classical algorithms
that estimate, with constant\r\nprecision, the singular values of a sparse matrix.
We show in particular that a\r\ncentral computational problem considered by quantum
algorithms for quantum\r\nchemistry (estimating the ground state energy of a local
Hamiltonian when\r\ngiven, as an additional input, a state sufficiently close
to the ground state)\r\ncan be solved efficiently with constant precision on a
classical computer. As a\r\ncomplementary result, we prove that with inverse-polynomial
precision, the same\r\nproblem becomes BQP-complete. This gives theoretical evidence
for the\r\nsuperiority of quantum algorithms for chemistry, and strongly suggests
that\r\nsaid superiority stems from the improved precision achievable in the quantum\r\nsetting.
We also discuss how this dequantization technique may help make\r\nprogress on
the central quantum PCP conjecture."

text: Due to their valuable properties (low weight, and good thermal and
mechanical properties), glass fiber reinforced thermoplastics are becoming increasingly
important. Fiber-reinforced thermoplastics are mainly manufactured by injection
molding and extrusion, whereby the extrusion compounding process is primarily
used to produce fiber-filled granulates. Reproducible production of high-quality
components requires a granulate in which the fiber length is even and high. However,
the extrusion process leads to the fact that fiber breakages can occur during
processing. To enable a significant quality enhancement, experimentally validated
modeling is required. In this study, short glass fiber reinforced thermoplastics
(polypropylene) were produced on two different twin-screw extruders. Therefore,
the machine-specific process behavior is of major interest regarding its influence.
First, the fiber length change after processing was determined by experimental
investigations and then simulated with the SIGMA simulation software. By comparing
the simulation and experimental tests, important insights could be gained and
the effects on fiber lengths could be determined in advance. The resulting fiber
lengths and distributions were different, not only for different screw configurations
(SC), but also for the same screw configurations on different twin-screw extruders.
This may have been due to manufacturer-specific tolerances.

text: "Recent advances in numerical methods significantly pushed forward the\r\nunderstanding
of electrons coupled to quantized lattice vibrations. At this\r\nstage, it becomes
increasingly important to also account for the effects of\r\nphysically inevitable
environments. In particular, we study the transport\r\nproperties of the Hubbard-Holstein
Hamiltonian that models a large class of\r\nmaterials characterized by strong
electron-phonon coupling, in contact with a\r\ndissipative environment. Even in
the one-dimensional and isolated case,\r\nsimulating the quantum dynamics of such
a system with high accuracy is very\r\nchallenging due to the infinite dimensionality
of the phononic Hilbert spaces.\r\nFor this reason, the effects of dissipation
on the conductance properties of\r\nsuch systems have not been investigated systematically
so far. We combine the\r\nnon-Markovian hierarchy of pure states method and the
Markovian quantum jumps\r\nmethod with the newly introduced projected purified
density-matrix\r\nrenormalization group, creating powerful tensor-network methods
for dissipative\r\nquantum many-body systems. Investigating their numerical properties,
we find a\r\nsignificant speedup up to a factor $\\sim 30$ compared to conventional\r\ntensor-network
techniques. We apply these methods to study dissipative\r\nquenches, aiming for
an in-depth understanding of the formation, stability, and\r\nquasi-particle properties
of bipolarons. Surprisingly, our results show that in\r\nthe metallic phase dissipation
localizes the bipolarons, which is reminiscent\r\nof an indirect quantum Zeno
effect. However, the bipolaronic binding energy\r\nremains mainly unaffected,
even in the presence of strong dissipation,\r\nexhibiting remarkable bipolaron
stability. These findings shed light on the\r\nproblem of designing real materials
exhibiting phonon-mediated\r\nhigh-$T_\\mathrm{C}$ superconductivity."
