text: In this article we prove meromorphic continuation of weighted zeta functions
in the framework of open hyperbolic systems by using the meromorphically continued
restricted resolvent of Dyatlov and Guillarmou (2016). We obtain a residue formula
proving equality between residues of weighted zetas and invariant Ruelle distributions.
We combine this equality with results of Guillarmou, Hilgert and Weich (2021)
in order to relate the residues to Patterson-Sullivan distributions. Finally we
provide proof-of-principle results concerning the numerical calculation of invariant
Ruelle distributions for 3-disc scattering systems.

text: AbstractThe 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.

text: This review examines the use of continuous-variable spectroscopy techniques
for investigating quantum coherence and light-matter interactions in semiconductor
systems with ultrafast dynamics. Special emphasis is placed on multichannel homodyne
detection as a powerful tool to measure the quantum coherence and the full density
matrix of a polariton system. Observations, such as coherence times that exceed
the nanosecond scale obtained by monitoring the temporal decay of quantum coherence
in a polariton condensate, are discussed. Proof-of-concept experiments and numerical
simulations that demonstrate the enhanced resourcefulness of the produced system
states for modern quantum protocols are assessed. The combination of tailored
resource quantifiers and ultrafast spectroscopy techniques that have recently
been demonstrated paves the way for future applications of quantum information
technologies.

text: 'AbstractBased on a literature review of
studies on teachers’ professional competence and related assessment tools, this
paper introduces a model of teacher education assessment. It is influenced by
Miller’s (1990) framework of assessment in medical education and includes, among
other aspects, performance assessments. This model is used to understand the potential
effects of transferring assessment tools into a digital format with assessment
feedback. Five examples for such a transfer will be discussed: three methods for
various aspects of communication, a test for pedagogical content knowledge, and
a test for content knowledge. All five are established instruments well-described
in terms of validity. All five have recently been transferred into a digital format.
The analysis of this transfer also reveals a potentially harmful effect of digital
assessment. The closer an assessment instrument is to assessing action-related
parts of professional competence, the more authenticity is required; however,
digitisation tends to decrease this authenticity. This suggests that an increasing
number of digital assessment tools in teacher education might result in an even
more dominant focus on knowledge tests, ignoring other parts of professional competence.
This article highlights the role of authenticity in validity and discusses the
most suitable assessment format to address various parts of professional competence.
It ends by highlighting the lessons learned from the transfer of assessment instruments
into a digital format that other academic disciplines might find interesting.'

text: Superconducting nanowire single-photon detectors (SNSPDs) show near
unity efficiency, low dark count rate, and short recovery time. Combining these
characteristics with temporal control of SNSPDs broadens their applications as
in active de-latching for higher dynamic range counting or temporal filtering
for pump-probe spectroscopy or LiDAR. To that end, we demonstrate active gating
of an SNSPD with a minimum off-to-on rise time of 2.4 ns and a total gate length
of 5.0 ns. We show how the rise time depends on the inductance of the detector
in combination with the control electronics. The gate window is demonstrated to
be fully and freely, electrically tunable up to 500 ns at a repetition rate of
1.0 MHz, as well as ungated, free-running operation. Control electronics to generate
the gating are mounted on the 2.3 K stage of a closed-cycle sorption cryostat,
while the detector is operated on the cold stage at 0.8 K. We show that the efficiency
and timing jitter of the detector is not altered during the on-time of the gating
window. We exploit gated operation to demonstrate a method to increase in the
photon counting dynamic range by a factor 11.2, as well as temporal filtering
of a strong pump in an emulated pump-probe experiment.

text: Spatial modes of light have become highly attractive to increase the dimension
and, thereby, security and information capacity in quantum key distribution (QKD).
So far, only transverse electric field components have been considered, while
longitudinal polarization components have remained neglected. Here, we present
an approach to include all three spatial dimensions of electric field oscillation
in QKD by implementing our tunable, on-a-chip vector beam decoder (VBD). This
inversely designed device pioneers the "preparation" and "measurement" of three-dimensionally
polarized mutually unbiased basis states for high-dimensional (HD) QKD and paves
the way for the integration of HD QKD with spatial modes in multifunctional on-a-chip
photonics platforms.

text: In real photonic quantum systems losses are an unavoidable factor limiting
the scalability to many modes and particles, restraining their application in
fields as quantum information and communication. For this reason, a considerable
amount of engineering effort has been taken in order to improve the quality of
particle sources and system components. At the same time, data analysis and collection
methods based on post-selection have been used to mitigate the effect of particle
losses. This has allowed for investigating experimentally multi-particle evolutions
where the observer lacks knowledge about the system's intermediate propagation
states. Nonetheless, the fundamental question how losses affect the behaviour
of the surviving subset of a multi-particle system has not been investigated so
far. For this reason, here we study the impact of particle losses in a quantum
walk of two photons reconstructing the output probability distributions for one
photon conditioned on the loss of the other in a known mode and temporal step
of our evolution network. We present the underlying theoretical scheme that we
have devised in order to model controlled particle losses, we describe an experimental
platform capable of implementing our theory in a time multiplexing encoding. In
the end we show how localized particle losses change the output distributions
without altering their asymptotic spreading properties. Finally we devise a quantum
civilization problem, a two walker generalisation of single particle recurrence
processes.

text: We present the fabrication of strain-free quantum dots in the In0.53Ga0.47As/In0.52Al0.48As-system
lattice matched to InP, as future sources for single and entangled photons for
long-haul fiber-based quantum communication in the optical C-band. We achieved
these quantum dots by local droplet etching via InAl droplets in an In0.52Al0.48As
layer and subsequent filling of the holes with In0.53Ga0.47As. Here, we present
detailed investigations of the hole morphologies measured by atomic force microscopy.
Statistical analysis of a set of nanoholes reveals a high degree of symmetry for
nearly half of them when etched at optimized temperatures. Overgrowth with 50–150 nm
In0.52Al0.48As increases their diameter and elongates the holes along the [01̄1]-direction.
By systematically scanning the parameter space, we were able to fill the holes
with In0.53Ga0.47As, and by capping the filled holes and performing photoluminescence
measurements, we observe photoluminescence emission in the O-band up into the
C-band depending on the filling height of the nanoholes.
