- Abstract: In this article, the possibility of generating non-classical light due to
Planck-scale effects is considered. For this purpose, a widely studied model of
deformation of the Heisenberg uncertainty relation is applied to single-mode
and multi-mode lights. The model leads to a deformed dispersion relation, which
manifests in an advancement in the time of arrival of photons. The key finding
is that the model also leads to an oscillatory pattern of squeezing of the
state of light. Furthermore, while the amplitude of the oscillations is
constant for energy eigenstates, it exhibits linear growth over time for
coherent states with the annihilation operator eigenvalue $\alpha \neq0 $. This
second case leads to the accumulation of squeezing and phase-space
displacement, which can be significant for astrophysical photons. In
particular, for $\alpha \sim 1$, coherent light in the optical spectrum emitted
at megaparsec distances would acquire squeezing with the amplitude of the order
unity. This suggests that measurements of the non-classical properties of light
originating from distant astrophysical sources may open a window to test these
predictions.

We study subradiance in a Bose-Einstein condensate positioned at the mode crossing of two optical cavities.
metastable density structures that suppress emission into one cavity mode prevent relaxation to the stationary, superradiant grating.
We reproduce these dynamics by a quantum mean field model, suggesting that subradiance shares characteristics with quasi-stationary states predicted in other long-range interacting systems.

Two non-identical quantum emitters, when placed within a cavity and coherently excited at the two-photon resonance, can reach stationary states of nearly maximal entanglement.
We show that this mechanism is merely one among a complex family of phenomena that can generate both stationary and metastable entanglement when driving the emitters at the two-photon resonance.

No class-B quantum density-matrix model is available to date, capable of accurately describing coherence and photon correlations within a unified theory.
Here we carry out a density-matrix theoretical approach for generic class-B lasers, and provide closed equations for the photonic and atomic reduced density matrix in the Fock basis of photons.
This model enables the study of few-photon bifurcations and non-classical photon correlations in class-B laser devices, also leveraging quantum descriptions of coherently coupled nanolaser arrays.

Entanglement in high-dimensional quantum systems, where one or more degrees of freedom of light are involved, offers increased information capacities and enables new quantum protocols.
Here, we demonstrate a functional source of high-dimensional, noise-resilient hyperentangled states encoded in time-frequency and vector-vortex structured modes.
We generate highly entangled photon pairs at telecom wavelength that we characterise via two-photon interference and quantum state tomography, achieving near-unity visibilities and fidelities.

We also find a time-domain where the particle density of the point source is governed by the propagation of a main wavefront.
The relative positions of these wavefronts are used to investigate the time-delay of quantum waves in the Klein-tunneling regime.

The $upsilon_alpha3$ scaling also corresponds to the semiclassical result whereby quantum fluctuations between the atoms have been neglected.
