text: AbstractTailored nanoscale quantum light
sources, matching the specific needs of use cases, are crucial building blocks
for photonic quantum technologies. Several different approaches to realize solid-state
quantum emitters with high performance have been pursued and different concepts
for energy tuning have been established. However, the properties of the emitted
photons are always defined by the individual quantum emitter and can therefore
not be controlled with full flexibility. Here we introduce an all-optical nonlinear
method to tailor and control the single photon emission. We demonstrate a laser-controlled
down-conversion process from an excited state of a semiconductor quantum three-level
system. Based on this concept, we realize energy tuning and polarization control
of the single photon emission with a control-laser field. Our results mark an
important step towards tailored single photon emission from a photonic quantum
system based on quantum optical principles.

text: We study the DC conductivity in potassium titanyl phosphate (KTiOPO4, KTP)
and its isomorphs KTiOAsO4 (KTA) and Rb1%K99%TiOPO4 (RKTP) and introduce a method
by which to reduce the overall ionic conductivity in KTP by a potassium nitrate
treatment. Furthermore, we create so-called gray tracking in KTP and investigate
the ionic conductivity in theses areas. A local unintended reduction of the ionic
conductivity is observed in the gray-tracked regions, which also induce additional
optical absorption in the material. We show that a thermal treatment in an oxygen-rich
atmosphere removes the gray tracking and brings the ionic conductivity as well
as the optical transmission back to the original level. These studies can help
to choose the best material and treatment for specific applications.

text: Inspired by plant grafting, grafted vortex beams can be formed through grafting
two or more helical phase profiles of optical vortex beams. Recently, grafted
perfect vortex beams (GPVBs) have attracted much attention due to their unique
optical properties and potential applications. However, the current method to
generate and manipulate GPVBs requires a complex and bulky optical system, hindering
further investigation and limiting its practical applications. Here, a compact
metasurface approach for generating and manipulating GPVBs in multiple channels
is proposed and demonstrated, which eliminates the need for such a complex optical
setup. A single metasurface is utilized to realize various superpositions of GPVBs
with different combinations of topological charges in four channels, leading to
asymmetric singularity distributions. The positions of singularities in the superimposed
beam can be further modulated by introducing an initial phase difference in the
metasurface design. The work demonstrates a compact metasurface platform that
performs a sophisticated optical task that is very challenging with conventional
optics, opening opportunities for the investigation and applications of GPVBs
in a wide range of emerging application areas, such as singular optics and quantum
science.

text: Subwavelength dielectric resonators assembled into metasurfaces have become
a versatile tool for miniaturizing optical components approaching the nanoscale.
An important class of metasurface functionalities is associated with asymmetry
in both the generation and transmission of light with respect to reversals of
the positions of emitters and receivers. The nonlinear light–matter interaction
in metasurfaces offers a promising pathway towards miniaturization of the asymmetric
control of light. Here we demonstrate asymmetric parametric generation of light
in nonlinear metasurfaces. We assemble dissimilar nonlinear dielectric resonators
into translucent metasurfaces that produce images in the visible spectral range
on being illuminated by infrared radiation. By design, the metasurfaces produce
different and completely independent images for the reversed direction of illumination,
that is, when the positions of the infrared emitter and the visible light receiver
are exchanged. Nonlinearity-enabled asymmetric control of light by subwavelength
resonators paves the way towards novel nanophotonic components via dense integration
of large quantities of nonlinear resonators into compact metasurface designs.

text: Quantum walks function as essential means to implement quantum simulators,
allowing one to study complex and often directly inaccessible quantum processes
in controllable systems. In this contribution, the notion of a driven Gaussian
quantum walk is introduced. In contrast to typically considered quantum walks
in optical settings, we describe the operation of the walk in terms of a nonlinear
map rather than a unitary operation, e.g., by replacing a beam-splitter-type coin
with a two-mode squeezer, being a process that is controlled and driven by a pump
field. This opens previously unattainable possibilities for quantum walks that
include nonlinear elements as core components of their operation, vastly extending
their range of applications. A full framework for driven Gaussian quantum walks
is developed, including methods to dynamically characterize nonlinear, quantum,
and quantum-nonlinear effects. Moreover, driven Gaussian quantum walks are compared
with their classically interfering and linear counterparts, which are based on
classical coherence of light rather than quantum superpositions. In particular,
the generation and boost of highly multimode entanglement, squeezing, and other
quantum effects are studied over the duration of the nonlinear walk. Importantly,
we prove the quantumness of the evolution itself, regardless of the input state.
A scheme for an experimental realization is proposed. Furthermore, nonlinear properties
of driven Gaussian quantum walks are explored, such as amplification that leads
to an ever increasing number of correlated quantum particles, constituting a source
of new walkers during the walk. Therefore, a concept for quantum walks is proposed
that leads to—and even produces—directly accessible quantum phenomena, and that
renders the quantum simulation of nonlinear processes possible.

text: "We study the complexity of problems solvable in deterministic polynomial
time\r\nwith access to an NP or Quantum Merlin-Arthur (QMA)-oracle, such as $P^{NP}$\r\nand
$P^{QMA}$, respectively. The former allows one to classify problems more\r\nfinely
than the Polynomial-Time Hierarchy (PH), whereas the latter\r\ncharacterizes physically
motivated problems such as Approximate Simulation\r\n(APX-SIM) [Ambainis, CCC
2014]. In this area, a central role has been played by\r\nthe classes $P^{NP[\\log]}$
and $P^{QMA[\\log]}$, defined identically to $P^{NP}$\r\nand $P^{QMA}$, except
that only logarithmically many oracle queries are\r\nallowed. Here, [Gottlob,
FOCS 1993] showed that if the adaptive queries made by\r\na $P^{NP}$ machine have
a \"query graph\" which is a tree, then this computation\r\ncan be simulated in
$P^{NP[\\log]}$.\r\n In this work, we first show that for any verification class\r\n$C\\in\\{NP,MA,QCMA,QMA,QMA(2),NEXP,QMA_{\\exp}\\}$,
any $P^C$ machine with a query\r\ngraph of \"separator number\" $s$ can be simulated
using deterministic time\r\n$\\exp(s\\log n)$ and $s\\log n$ queries to a $C$-oracle.
When $s\\in O(1)$ (which\r\nincludes the case of $O(1)$-treewidth, and thus also
of trees), this gives an\r\nupper bound of $P^{C[\\log]}$, and when $s\\in O(\\log^k(n))$,
this yields bound\r\n$QP^{C[\\log^{k+1}]}$ (QP meaning quasi-polynomial time).
We next show how to\r\ncombine Gottlob's \"admissible-weighting function\" framework
with the\r\n\"flag-qubit\" framework of [Watson, Bausch, Gharibian, 2020], obtaining
a\r\nunified approach for embedding $P^C$ computations directly into APX-SIM\r\ninstances
in a black-box fashion. Finally, we formalize a simple no-go\r\nstatement about
polynomials (c.f. [Krentel, STOC 1986]): Given a multi-linear\r\npolynomial $p$
specified via an arithmetic circuit, if one can \"weakly\r\ncompress\" $p$ so
that its optimal value requires $m$ bits to represent, then\r\n$P^{NP}$ can be
decided with only $m$ queries to an NP-oracle."

text: Secret sharing is a well-established cryptographic primitive for storing
highly sensitive information like encryption keys for encoded data. It describes
the problem of splitting a secret into different shares, without revealing any
information to its shareholders. Here, we demonstrate an all-optical solution
for secret sharing based on metasurface holography. In our concept, metasurface
holograms are used as spatially separable shares that carry encrypted messages
in the form of holographic images. Two of these shares can be recombined by bringing
them close together. Light passing through this stack of metasurfaces accumulates
the phase shift of both holograms and optically reconstructs the secret with high
fidelity. In addition, the hologram generated by each single metasurface can uniquely
identify its shareholder. Furthermore, we demonstrate that the inherent translational
alignment sensitivity between two stacked metasurface holograms can be used for
spatial multiplexing, which can be further extended to realize optical rulers.

text: Topological photonic crystals (TPhCs) provide robust manipulation of light
with built-in immunity to fabrication tolerances and disorder. Recently, it was
shown that TPhCs based on weak topology with a dislocation inherit this robustness
and further host topologically protected lower-dimensional localized modes. However,
TPhCs with weak topology at optical frequencies have not been demonstrated so
far. Here, we use scattering-type scanning near-field optical microscopy to verify
mid-bandgap zero-dimensional light localization close to 100 THz in a TPhC with
nontrivial Zak phase and an edge dislocation. We show that because of the weak
topology, differently extended dislocation centers induce similarly strong light
localization. The experimental results are supported by full-field simulations.
Along with the underlying fundamental physics, our results lay a foundation for
the application of TPhCs based on weak topology in active topological nanophotonics,
and nonlinear and quantum optic integrated devices because of their strong and
robust light localization.

text: "Abstract\r\n For a compact
Riemannian locally symmetric space $\\mathcal M$ of rank 1 and an associated vector
bundle $\\mathbf V_{\\tau }$ over the unit cosphere bundle $S^{\\ast }\\mathcal
M$, we give a precise description of those classical (Pollicott–Ruelle) resonant
states on $\\mathbf V_{\\tau }$ that vanish under covariant derivatives in the
Anosov-unstable directions of the chaotic geodesic flow on $S^{\\ast }\\mathcal
M$. In particular, we show that they are isomorphically mapped by natural pushforwards
into generalized common eigenspaces of the algebra of invariant differential operators
$D(G,\\sigma )$ on compatible associated vector bundles $\\mathbf W_{\\sigma }$
over $\\mathcal M$. As a consequence of this description, we obtain an exact band
structure of the Pollicott–Ruelle spectrum. Further, under some mild assumptions
on the representations $\\tau$ and $\\sigma$ defining the bundles $\\mathbf V_{\\tau
}$ and $\\mathbf W_{\\sigma }$, we obtain a very explicit description of the generalized
common eigenspaces. This allows us to relate classical Pollicott–Ruelle resonances
to quantum eigenvalues of a Laplacian in a suitable Hilbert space of sections
of $\\mathbf W_{\\sigma }$. Our methods of proof are based on representation theory
and Lie theory."
