Modified nonclassical coherent state: Squeezing, antibunching, sub-Poissonian photon statistics, realization scheme with the {chi}{sup (2)}-nonlinearity, and generation of a macroscopic entangled state

Journal Article · · Journal of Experimental and Theoretical Physics
The nonlinear {chi}{sup (2)} Mach-Zehnder interferometer is proposed as a device for conditional generation of a modified coherent nonclassical state. We show that the generated macroscopic state exhibits nonclassical effects, such as squeezing, photon antibunching, and sub-Poissonian statistics. The modified coherent state generates a macroscopic entangled state. The scheme works without the photon number resolving detection but requires high-efficiency photodetectors. We explain the mechanism of generation of the modified coherent non-classical state.
