Abstract
New scheme to conditionally produce two types of macroscopic entangled states is developed. The studied system consists of the system of coupled down converters with type-I phase matching pumped simultaneously by powerful optical fields in coherent states, one auxiliary photon in superposition state of two input modes and projective measurement system used in output generated modes. Given scheme works without photon number resolving detection. Moreover, an analysis of “separation” between components of the entangled states and influence of detector inefficiency on fidelity of the scheme is accomplished.
