We establish the path integral formalism for nondegenerate parametric amplifiers in the entangled state representations. Its advantage in obtaining the energy level gap of this system is analyzed.
In 3-mode Fock space we find a new tripartite entangled state |α,γ〉λ, which make up a new quantumparametric down-conversion amplifier. Application of the state is briefly discussed.
