QUANTUM COMPUTATIONS AND ATOM-FIELD ENTANGLED STATES IN JAYNES-CUMMINGS GENERALIZED MODEL

Atom-field entanglement in two-atom system in different initial states in Jay-nes-Cummings model with degenerate two photon transition with dependant from intensity of the field of parameter of atom-field interaction is considered. It is shown that consideration of discontency of parameter of atom-field interaction for some initial states of atoms leads to damping or collapse of instant death of entanglement effect and changes of disentanglement time.
