text: Boson sampling is a key candidate for demonstrating quantum advantage
and has already yielded significant advances in quantum simulation, machine learning,
and graph theory. In this work, a unification and extension of distinct forms
of boson sampling is developed. The devised protocol merges discrete-variable
scattershot boson sampling with continuous-variable Gaussian boson sampling. Therefore,
it is rendered possible to harness the complexity of more interesting states,
such as squeezed photons, in advanced sampling protocols. A generating function
formalism is developed for the joint description of multiphoton and multimode
light undergoing Gaussian transformations. The resulting analytical tools enable
one to explore interfaces of different photonic quantum-information-processing
platforms. A numerical simulation of unified sampling is carried out, benchmarking
its performance, complexity, and scalability. Entanglement is characterized to
exemplify the generation of quantum correlations from the nonlinear interactions
of a unified sampler.

text: 'Entangled two-mode Gaussian states constitute an important building
block for continuous variable quantum computing and communication protocols. In
this work, we theoretically study two-mode bipartite states, which are extracted
from multimode light generated via type-II parametric downconversion (PDC) in
lossy waveguides. For these states, we demonstrate that the squeezing quantifies
entanglement and we construct a measurement basis, which results in the maximal
bipartite entanglement. We illustrate our findings by numerically solving the
spatial master equation for PDC in a Markovian environment. The optimal measurement
modes are compared with two widely used broadband bases: the Mercer–Wolf basis
(the first-order coherence basis) and the Williamson–Euler basis.'

text: Samples of dielectric optical waveguides of rib or strip type in thin-film
lithium niobate (TFLN) technology are characterized with respect to their optical
loss using the Fabry-Pérot method. Attributing the losses mainly to sidewall roughness,
we employ a simple perturbational procedure, based on rigorously computed mode
profiles of idealized channels, to estimate the attenuation for waveguides with
different cross sections. A single fit parameter suffices for an adequate modelling
of the effect of the waveguide geometry on the loss levels.

text: Lateral leakage of TM modes in dielectric optical waveguides of rib/ridge
or strip-loaded types can be fully suppressed, if the waveguide core is formed
not through a strip that protrudes at one side (up) from the remaining lateral
guiding slab, but through parallel strips on both sides (up and down), such that
the resulting cross section becomes vertically symmetric. The fairly general arguments
underlying the leakage suppression apply to TM modes of all orders simultaneously,
and are independent of wavelength. These plus-shaped waveguides support strictly
guided, non-leaky TM modes for, in principle, arbitrarily shallow etching.

text: Phased arrays are vital in communication systems and have received significant
interest in the field of optoelectronics and photonics, enabling a wide range
of applications such as LiDAR, holography, wireless communication, etc. In this
work, we present a blazed grating antenna that is optimized to have upward radiation
efficiency as high as 80% with a compact footprint of 3.5 μm × 2 μm at an operational
wavelength of 1.55 μm. Our numerical investigations demonstrate that this antenna
in a 64 × 64 phased array configuration is capable of producing desired far-field
radiation patterns. Additionally, our antenna possesses a low side lobe level
of -9.7 dB and a negligible reflection efficiency of under 1%, making it an attractive
candidate for integrated optical phased arrays.

text: 'Dielectric slab waveguides made of thin-film-lithium-niobate (TFLN) media
are consid-ered, for operation in the linear regime. We outline and implement
a largely analytic procedure forrigorous modal analysis of three-layer slabs with
birefringent, anisotropic core. For Z-cut wave-guides, the slab eigenmode problem
separates into uncoupled sets of scalar equations for TE andTM modes. Slabs in
X-cut configuration support mostly mildly hybrid eigenmodes, with clear pre-dominant
TE or TM polarization, and with effective indices that depend on the propagation
directionof the modes, relative to the crystal axes. Strong hybridization can
be observed for near degeneratemodes in singular configurations without vertical
symmetry, or in symmetric slabs where two nearlydegenerate modes are of the same
symmetry class. Dispersion curves for slab thickness and propa-gation angle are
discussed, for slabs with oxide and air cover. '

text: 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.

text: "In the SUPER scheme (Swing-UP of the quantum EmitteR population),
excitation of a quantum emitter is achieved with two off-resonant, red-detuned
laser pulses. This allows the generation of high-quality single photons without
the need of complex laser stray light suppression or careful spectral filtering.
In the present work, we extend this promising method to quantum emitters, specifically
semiconductor quantum dots, inside a resonant optical cavity. A significant advantage
of the SUPER scheme is identified in that it eliminates re-excitation of the quantum
emitter by suppressing photon emission during the excitation cycle. This, in turn,
leads to almost ideal single-photon purity, overcoming a major factor typically
limiting the quality of photons generated with quantum emitters in high-quality
cavities. We further find that for cavity-mediated biexciton emission of degenerate
photon pairs, the SUPER scheme leads to near-perfect biexciton initialization
with very high values of polarization entanglement of emitted photon pairs.\r\n

text: "Abstract\r\n Topological states
have been widely investigated in different types of systems and lattices. In the
present work, we report on topological edge states in double-wave (DW) chains,
which can be described by a generalized Aubry-André-Harper (AAH) model. For the
specific system of a driven-dissipative exciton polariton system we show that
in such potential chains, different types of edge states can form. For resonant
optical excitation, we further find that the optical nonlinearity leads to a multistability
of different edge states. This includes topologically protected edge states evolved
directly from individual linear eigenstates as well as additional edge states
that originate from nonlinearity-induced localization of bulk states. Extending
the system into two dimensions (2D) by stacking horizontal DW chains in the vertical
direction, we also create 2D multi-wave lattices. In such 2D lattices multiple
Su–Schrieffer–Heeger (SSH) chains appear along the vertical direction. The combination
of DW chains in the horizonal and SSH chains in the vertical direction then results
in the formation of higher-order topological insulator corner states. Multistable
corner states emerge in the nonlinear regime."
