In this thesis, we studied the entanglement properties of a system composed of one-to-three atoms, interacting stochastically with a cavity field. We also studied the entanglement properties of the systems under random phase telegraph noise. We obtained exact solutions for each systems. In order to examine atom-field, atom-atom and field-field entanglement in two level atom model we used the Jaynes-Cummings model. We will mainly focus on atom-atom entanglement. A strong atom-atom entanglement is observed in a stationary case. It has been observed that a strong noise helped in creating stationary atom-atom entanglement. We confined our research to random phase telegraph noise in order to understand the effects on atom-field interaction.
