text: We report a titanium indiffused waveguide resonator featuring an integrated
electro-optic modulator for cavity length stabilisation that produces close to
5 dB of squeezed light at 1550 nm (2.4 dB directly measured). The resonator is
locked on resonance for tens of minutes with 70 mW of SH light incident on the
cavity, demonstrating that photorefraction can be mitigated. Squeezed light production
concurrent with cavity length stabilisation utilising the integrated EOM is demonstrated.
The device demonstrates the suitability of this platform for squeezed light generation
in network applications, where stabilisation to the reference field is typically
necessary.

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.

continued weighted zeta functions established by the authors\r\ntogether with
Barkhofen (2021). To make this applicable for numerics we express\r\nthe weighted

text: In this work, we utilize thin dielectric meta-atoms placed on a silver substrate
to efficiently enhance and manipulate the third-harmonic generation. We theoretically
and experimentally reveal that when the structural symmetry of the meta-atom is
incompatible with the lattice symmetry of an array, some generalized nonlinear
geometric phases appear, which offers new possibilities for harmonic generation
control beyond the accessible symmetries governed by the selection rule. The underlying
mechanism is attributed to the modified rotation of the effective principal axis
of a dense meta-atom array, where the strong coupling among the units gives rise
to a generalized linear geometric phase modulation of the pump light. Therefore,
nonlinear geometric phases carried by third-harmonic emissions are the natural
result of the wave-mixing process among the modes excited at the fundamental frequency.
This mechanism further points out a new strategy to predict the nonlinear geometric
phases delivered by the nanostructures according to their linear responses. Our
design is simple and efficient and offers alternatives for the nonlinear meta-devices
that are capable of flexible photon generation and manipulation.

text: "Savitch's theorem states that NPSPACE computations can be simulated in\r\nPSPACE.
We initiate the study of a quantum analogue of NPSPACE, denoted\r\nStreaming-QCMASPACE
(SQCMASPACE), where an exponentially long classical proof\r\nis streamed to a
poly-space quantum verifier. Besides two main results, we also\r\nshow that a
quantum analogue of Savitch's theorem is unlikely to hold, as\r\nSQCMASPACE=NEXP.
For completeness, we introduce Streaming-QMASPACE (SQMASPACE)\r\nwith an exponentially
long streamed quantum proof, and show SQMASPACE=QMA_EXP\r\n(quantum analogue of
NEXP). Our first main result shows, in contrast to the\r\nclassical setting, the
solution space of a quantum constraint satisfaction\r\nproblem (i.e. a local Hamiltonian)
is always connected when exponentially long\r\nproofs are permitted. For this,
we show how to simulate any Lipschitz\r\ncontinuous path on the unit hypersphere
via a sequence of local unitary gates,\r\nat the expense of blowing up the circuit
size. This shows quantum\r\nerror-correcting codes can be unable to detect one
codeword erroneously\r\nevolving to another if the evolution happens sufficiently
slowly, and answers\r\nan open question of [Gharibian, Sikora, ICALP 2015] regarding
the Ground State\r\nConnectivity problem. Our second main result is that any SQCMASPACE
computation\r\ncan be embedded into \"unentanglement\", i.e. into a quantum constraint\r\nsatisfaction
problem with unentangled provers. Formally, we show how to embed\r\nSQCMASPACE
into the Sparse Separable Hamiltonian problem of [Chailloux,\r\nSattath, CCC 2012]
(QMA(2)-complete for 1/poly promise gap), at the expense of\r\nscaling the promise
gap with the streamed proof size. As a corollary, we obtain\r\nthe first systematic
construction for obtaining QMA(2)-type upper bounds on\r\narbitrary multi-prover
interactive proof systems, where the QMA(2) promise gap\r\nscales exponentially
with the number of bits of communication in the\r\ninteractive proof."

text: The achievement of a flat metasurface has realized extraordinary control over
light–matter interaction at the nanoscale, enabling widespread use in imaging,
holography, and biophotonics. However, three-dimensional metasurfaces with the
potential to provide additional light–matter manipulation flexibility attract
only little interest. Here, we demonstrate a three-dimensional metasurface scheme
capable of providing dual phase control through out-of-plane plasmonic resonance
of L-shape antennas. Under circularly polarized excitation at a specific wavelength,
the L-shape antennas with rotating orientation angle act as spatially variant
three-dimensional tilted dipoles and are able to generate desire phase delay for
different polarization components. Generalized Snell's law is achieved for both
in-plane and out-of-plane dipole components through arranging such L-shape antennas
into arrays. These three-dimensional metasurfaces suggest a route for wavefront
modulation and a variety of nanophotonic applications.

- lang: eng
text: "Dispersion is present in every optical setup and is often an undesired effect,
especially in nonlinear-optical experiments where ultrashort laser pulses are
needed. Typically, bulky pulse compressors consisting of gratings or prisms are
used\r\nto address this issue by precompensating the dispersion of the optical
components. However, these devices are only able to compensate for a part of the
dispersion (second-order dispersion). Here, we present a compact pulse-shaping
device that uses plasmonic metasurfaces to apply an arbitrarily designed spectral
phase delay allowing for a full dispersion control. Furthermore, with specific
phase encodings, this device can be used to temporally reshape the incident laser
pulses into more complex pulse forms such as a double pulse. We verify the performance
of our device by using an SHG-FROG measurement setup together with a retrieval
algorithm to extract the dispersion that our device applies to an incident laser
pulse."

text: The nonlinear optical response of an ensemble of semiconductor quantum dots
is analyzed by wave-mixing processes, where we focus on four-wave mixing with
two incident pulses. Wave-mixing experiments are often described with semiclassical
models, where the light is modeled classically and the material quantum mechanically.
Here, however, we use a fully quantized model, where the light is given by a quantum
state of light. Quantum light involves more degrees of freedom than classical
light as e.g., its photon statistics and quantum correlations, which is a promising
resource for quantum devices, such as quantum memories. The light-matter interaction
is treated with a Jaynes-Cummings type model and the quantum field is given by
a single mode since the quantum dots are embedded in a microcavity. We present
numerical simulations of the four-wave-mixing response of a homogeneous system
for pulse sequences and find a significant dependence of the result on the photon
statistics of the incident pulses. The model constitutes a problem with a large
state space which arises from the frequency distribution of the transition energies
of the inhomogeneously broadened quantum dot ensemble that is coupled with a quantum
light mode. Here we approximate the dynamics by summing over individual quantum
dot-microcavity systems. Photon echoes arising from the excitation with different
quantum states of light are simulated and compared.

text: Perfect vector vortex beams (PVVBs) have attracted considerable interest due
to their peculiar optical features. PVVBs are typically generated through the
superposition of perfect vortex beams, which suffer from the limited number of
topological charges (TCs). Furthermore, dynamic control of PVVBs is desirable
and has not been reported. We propose and experimentally demonstrate hybrid grafted
perfect vector vortex beams (GPVVBs) and their dynamic control. Hybrid GPVVBs
are generated through the superposition of grafted perfect vortex beams with a
multifunctional metasurface. The generated hybrid GPVVBs possess spatially variant
rates of polarization change due to the involvement of more TCs. Each hybrid GPVVB
includes different GPVVBs in the same beam, adding more design flexibility. Moreover,
these beams are dynamically controlled with a rotating half waveplate. The generated
dynamic GPVVBs may find applications in the fields where dynamic control is in
high demand, including optical encryption, dense data communication, and multiple
particle manipulation.

text: Interference between single photons is key for many quantum optics experiments
and applications in quantum technologies, such as quantum communication or computation.
It is advantageous to operate the systems at telecommunication wavelengths and
to integrate the setups for these applications in order to improve stability,
compactness and scalability. A new promising material platform for integrated
quantum optics is lithium niobate on insulator (LNOI). Here, we realise Hong-Ou-Mandel
(HOM) interference between telecom photons from an engineered parametric down-conversion
source in an LNOI directional coupler. The coupler has been designed and fabricated
in house and provides close to perfect balanced beam splitting. We obtain a raw
HOM visibility of (93.5 ± 0.7) %, limited mainly by the source performance and
in good agreement with off-chip measurements. This lays the foundation for more
sophisticated quantum experiments in LNOI.
