- Abstract: The Schr\"{o}dinger dynamics of photon excitation numbers together with
entanglement in two non-resonant time-dependent coupled oscillators is
investigated. By considering $ \pi-$periodically pumped parameters and using
suitable transformations, we obtain the coupled Meissner oscillators.
Consequently, our analytical study shows two interesting results, which can be
summarized as follows. (i): Classical instability of classical analog of
quantum oscillators and photon excitation {averages $\left\langle
N_{j}\right\rangle $} are strongly correlated. (ii): Photon excitation's and
entanglement are connected to each other. These results can be used to shed
light on the link between quantum systems and their classical counterparts.
Also it allow to control entanglement by engineering only classical systems
where the experiments are less expensive.

Quantum correlations in four-wave-mixing from ensembles of cold two-level atoms may prevail without filtering over background light.
We detail the experimental procedure and the variation of the quantum correlation with various parameters of the system.
The non-classical aspects of the signal occur for short timescales, but the long timescales carry as well the classical correlations of the system.

We study theoretically an array of two-level qubits moving relative to a one-dimensional waveguide.

We develop a comprehensive general theoretical framework that incorporates both perturbative diagrammatic techniques and a rigorous master-equation approach.

We show that for a class of quantum light spectroscopy (QLS) experiments, identical signals can be obtained by replacing the biphotons with classical-like coherent states of light.
This analysis shows that understanding the equivalence between entangled biphoton probes and carefully designed classical-like coherent state probes leads to quantum-inspired experiments.

The radiative quantum cascade, i.e. the consecutive emission of photons from a ladder of energy levels, is of fundamental importance in quantum optics.
Here, we use exciton polaritons to explore the cascaded emission of photons in the regime where individual transitions of the ladder are not resolved.
Remarkably, the measured photon-photon correlations exhibit a strong dependence on the polariton energy, and therefore on the underlying polaritonic interaction strength.
