Seventy five years ago, three remarkable papers by Schrödinger, Kennard and Darwin were
published. They were devoted to the evolution of Gaussian wave packets for an oscillator, a …

We study photon blockade and antibunching in the cavity of an optomechanical system in
which the mechanical resonator is coupled to a two-level system (TLS). In particular, we …

The term'nonclassical states' refers to the quantum states that cannot be produced in the
usual sources of light, such as lasers or lamps, rather than those requiring more …

We theoretically analyze the Einstein-Podolsky-Rosen (EPR) correlation, the quadrature
squeezing, and the continuous-variable quantum teleportation when considering non …

Analyses of phenomena exhibiting finite-time decay of quantum entanglement have recently
attracted considerable attention. Such decay is often referred to as sudden vanishing (or …

Two Kerr-squeezed optical beams can be combined in a beam splitter to produce non-
Gaussian continuous-variable entangled states. We characterize the non-Gaussian nature …

In this paper, two distinct classes of generalized deformed Kerr states are introduced by
considering the standard and deformed Kerr mediums, when the initial field state that enters …

Axionlike particles (ALPs) are promising dark matter candidates. They are typically
described by a classical field, motivated by large phase space occupation numbers. Here …

In this paper, we first analyze a parametric oscillator with both mass and frequency time-
dependent. We show that the evolution operator can be obtained from the evolution operator …

Non-Gaussian states represent a powerful resource for quantum information protocols in the
continuous variables regime. Cat states, in particular, have been produced in the motional …
