text: "Exceptional points (EPs), with their intriguing spectral topology,
have attracted considerable attention in a broad range of physical systems, with
potential sensing applications driving much of the present research in this field.
Here, we investigate spectral topology and EPs in systems with significant nonlinearity,
exemplified by a nonequilibrium exciton-polariton condensate. With the possibility
to control loss and gain and nonlinearity by optical means, this system allows
for a comprehensive analysis of the interplay of nonlinearities (Kerr type and
saturable gain) and non-Hermiticity. Not only do we find that EPs can be intentionally
shifted in parameter space by the saturable gain, but we also observe intriguing
rotations and intersections of Riemann surfaces and find nonlinearity-enhanced
sensing capabilities. With this, our results illustrate the potential of tailoring
spectral topology and related phenomena in non-Hermitian systems by nonlinearity.\r\n

text: AbstractThermal stability is crucial for
doped organic semiconductors (OSCs) and their applications in organic thermoelectric
(OTE) devices. However, the capacity of n‐dopants to produce thermally stable
n‐doped OSC films has not been thoroughly explored, with few reports of high thermal
stability. Here, a novel n‐dopant, phosphazenium tetrafluoroborate (P2BF4)
is introduced, which effectively induces n‐doping in N2200, P(PzDPP‐CT2) and several
other commonly used OSCs. Remarkably, the electrical conductivity of P2BF4‐doped
OSC films remains almost unchanged even after heating at temperatures > 150 °C
for 24 h, far superior to the films doped with benchmark N‐DMBI. The exceptional
thermal stability observed in P2BF4‐doped
P(PzDPP‐CT2) films allows for stable operation of the corresponding organic thermoelectric
devices at 150 °C for 16 h, a milestone not previously achieved. This study offers
valuable insights into the development of n‐dopants capable of producing OSCs
with outstanding thermal stability, paving the way for the practical realization
of OTE devices with enhanced operation stability.

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: Phonons in solid-state quantum emitters play a crucial role in their performance
as photon sources in quantum technology. For resonant driving, phonons dampen
the Rabi oscillations resulting in reduced preparation fidelities. The phonon
spectral density, which quantifies the strength of the carrier-phonon interaction,
is non-monotonous as a function of energy. As one of the most prominent consequences,
this leads to the reappearance of Rabi rotations for increasing pulse power, which
was theoretically predicted in Phys. Rev. Lett. 98, 227403 (2007). In this paper
we present the experimental demonstration of the reappearance of Rabi rotations.

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: 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.
