Quantum information entropy and multi-qubit entanglement
TL;DR: In this article, the authors provide a general expression for the entanglement in a multi-level system and show that the mixed-state and specific eigenstates of the two or three-level systems posses remarkable entagglement properties that can reveal new insight into quantum correlations present in the multilevel models.

Tripartite entanglement dynamics and entropic squeezing of a three-level atom interacting with a bimodal cavity field
TL;DR: In this article, the interaction between a Λ-type three-level atom and two quantized electromagnetic fields which are simultaneously injected in a bichromatic cavity surrounded by a Kerr medium in the presence of field-field interaction and detuning parameters is investigated.

Dynamics of entanglement of a three-level atom in motion interacting with two coupled modes including parametric down conversion
TL;DR: In this paper, a model by which the interaction between a motional three-level atom and a two-mode field injected simultaneously in a bichromatic cavity is considered; the threelevel atom is assumed to be in a Λ -type configuration.

Comparison of quantum and semiclassical radiation theories with application to the beam maser
E.T. Jaynes,F.W. Cummings +1 more
TL;DR: In this article, it was shown that the semiclassical theory, when extended to take into account both the effect of the field on the molecules and the effects of the molecules on the field, reproduces the same laws of energy exchange and coherence properties as the quantized field theory, even in the limit of one or a few quanta in the field mode.

Manipulating quantum entanglement with atoms and photons in a cavity
TL;DR: The concept of entanglement plays an essential role in quantum physics as mentioned in this paper, and it is also essential to understand decoherence, the process accounting for the classical appearance of the macroscopic world.

TL;DR: In this article, the exact solution for a problem of identical two-level molecules interacting through a dipole coupling with a single-mode quantized radiation field at resonance is given, and approximate expressions for the eigenvectors and eigenvalues for the ground and low-lying excited states, as well as the most highly excited states are developed and compared with the exact results.

Observation of quantum collapse and revival in a one-atom maser.
TL;DR: The dynamics of the interaction of a single Rydberg atom with a single mode of an electromagnetic field in a superconducting cavity was investigated and the quantum collapse and revival predicted by the Jaynes-Cummings model were demonstrated experimentally for the first time.

TL;DR: The Jaynes-Cummings model was used to examine the classical aspects of spontaneous emission and reveal the existence of Rabi oscillations in atomic excitation probabilities for fields with sharply defined energy as mentioned in this paper.
