| Abstract: | From the viewpoint of quantum information, this paper proposes a
concept and a definition of the atomic optimal entropy squeezing
sudden generation (AOESSG) for the system of an effective two-level
moving atom which entangles with the two-mode coherent fields. It
also researches the relationship between the AOESSG and
entanglement sudden death of the atom-fields, and discusses the
influences of atomic initial state on the AOESSG and obtains the
system parameter which controls the AOESSG. |
