text: Non-Hermitian systems hosting exceptional points (EPs) exhibit enhanced sensitivity
and unconventional mode dynamics. Going beyond isolated EPs, here we report on
the existence of exceptional rings (ERs) in planar optical resonators with specific
form of circular dichroism and TE-TM splitting. Such exceptional rings possess
intriguing topologies as discussed earlier for condensed matter systems, but they
remain virtually unexplored in presence of nonlinearity, for which our photonic
platform is ideal. We find that when Kerr-type nonlinearity (or saturable gain)
is introduced, the linear ER splits into two concentric ERs, with the larger-radius
ring being a ring of third-order EPs. Transitioning from linear to nonlinear regime,
we present a rigorous analysis of spectral topology and report enhanced and adjustable
perturbation response in the nonlinear regime. Whereas certain features are specific
to our system, the results on non-Hermitian spectral topology and nonlinearity-enhanced
perturbation response are generic and equally relevant to a broad class of other
nonlinear non-Hermitian systems, providing a universal framework for engineering
ERs and EPs in nonlinear non-Hermitian systems.

text: We introduce a new classification of multimode states with a fixed
number of photons. This classification is based on the factorizability of homogeneous
multivariate polynomials and is invariant under unitary transformations. The classes
physically correspond to field excitations in terms of single and multiple photons,
each of which is in an arbitrary irreducible superposition of quantized modes.
We further show how the transitions between classes are rendered possible by photon
addition, photon subtraction, and photon-projection nonlinearities. We explicitly
put forward a design for a multilayer interferometer in which the states for different
classes can be generated with state-of-the-art experimental techniques. Limitations
of the proposed designs are analyzed using the introduced classification, providing
a benchmark for the robustness of certain states and classes.

text: Bell measurements, entailing the projection onto one of the Bell states,
play a key role in quantum information and communication, where the outcome of
a variety of protocols crucially depends on the success probability of such measurements.
Although in the case of qubit systems, Bell measurements can be implemented using
only linear optical components, the same result is no longer true for qudits,
where at least the use of ancillary photons is required. In order to circumvent
this limitation, one possibility is to introduce nonlinear effects. In this work,
we adopt the latter approach and propose a scalable Bell measurement scheme for
high-dimensional states, exploiting multiple squeezer devices applied to a linear
optical circuit for discriminating the different Bell states. Our approach does
not require ancillary photons, is not limited by the dimension of the quantum
states, and is experimentally scalable, thus paving the way toward the realization
of an effective high-dimensional Bell measurement.

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: 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: 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.
