TL;DR: In this paper, the quantum entanglement properties of two-mode coherent fields interacting with a two-level atom via the two-photon transition were investigated, and it was shown that three types of entangled states can be prepared via twomode coherent field interactions with a 2 level atom and choosing appropriately the initial state parameters of the system.

TL;DR: In this article, the quantum entropic dynamics of the phonons and trapped ion were studied and the authors obtained a general evolution operator of the trapped ion system, which is the same as the one of the field in the Jaynes-Cummings model.

TL;DR: In this article, the entropy of entanglement of the output state from a Mach-Zehnder interferometer for the two-mode squeezed vacuum state input was numerically analyzed, and it was shown that if the internal phase shift of the interferometers is adjusted to the value of 0 or π, the entangling characteristic of the input state is efficiently preserved at the output.

TL;DR: In this article, the authors studied the dynamical behavior of the ionic inversion in a trapped ion system in running-wave lasers and discussed the properties of entanglement between the ion and phonons and the statistics of the vibrational phonon field.

TL;DR: In this paper, the entropy and the entanglement of an electromagnetically induced transparency system were studied by using quantum reduced entropy and quantum relative entropy, and it was shown that the minimum value of the atomic reduced entropy may be regarded as an entropy criterion on the electromagnetic induced transparency occurring.
