摘要: By using the theory of cavity QED, we study the system in which a two-level atom interacts with a cavity in the case of large detuning. Through the selective detecting of atomic state, Schr\"{o}dinger cat states and entangled coherent states are easily generated. When the atom is driven by a weak classical field and the cavity field is in the Schr\"{o}dinger cat state, we study the conditions of generating the Fock states and the maximal success probability. The maximal success probability in our scheme is larger than the previous one.
