Asymmetric steering is an effect whereby an inseparable bipartite system can be found to be
described by either quantum mechanics or local hidden variable theories depending on …

We study the squeezing dynamics in a Kerr-nonlinear oscillator, and quantify the
metrological usefulness of the resulting states. Even if the nonlinearity limits the attainable …

In the present manuscript, we investigate qualitatively the quantum entanglement and
coherence in two atoms coupled to a quantized field in the existence of Kerr medium and …

Nonlocal quantum correlations are important for potential applications in quantum optics
and quantum information. Multipartite quantum correlations are relevant to access to high …

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 …

Quantum entanglement is an important resource for quantum information processing,
quantum communication, quantum computation and quantum sensing. Hence, several …

We investigate two coupled nonlinear cavities that are coherently driven in a dissipative
environment. We perform semiclassical, numerical, and analytical quantum studies of this …

We investigate how entanglement spreads along small Bose-Hubbard chains, with only the
first well initially occupied by a mesoscopic number of atoms, as the number of sites …

We examine theoretically the driven-dissipative Bose-Hubbard dimer in the optical bistable
regime. Various approximation schemes based on a Gutzwiller mean-field decoupling are …

We propose three criteria for identifying continuous variable entanglement between two
many-particle systems with no restrictions on the quantum state of the local oscillators used …
