The new n-mode coherent–entangled state and its application

A new kind of continuous variable n-mode coherent–entangled state (CV-NCES) |x2, x3, ⋅⋅⋅, xn, α〉 is proposed, which exhibits both the properties of a coherent state and an entangled state, and spans a complete and orthonormal representation. The conjugate state of CV-NCES is derived by the Fourier transformation. Moreover, a simple experimental protocol of generating a CV-NCES is proposed by using beam splitters. As applications of this CV-NCES in quantum optics, a new n-mode squeezing-Fresnel operator is constructed.
