The study of higher-order nonclassical properties of the squeezing-enhanced coherent state

Tóm tắt

In this paper, we study the nonclassical properties such as Hillery’s higher-order squeezing effect, higher-order sub-Poissonian statistic, and higher-order antibunching of the squeezing-enhanced coherent state. The results show that the squeezing-enhanced coherent state is stronger squeezing at higher-order, comparing the values of squeezing effect at higher-order to choose the suitable value to enhanced accurate measurements in quantum information, quantum optic, and show characteristic of higher-order sub-Poissonian statistic and higher-order antibunching. All results indicate that higher-order nonclassical properties of the squeezing-enhanced coherent state have stronger than the normal order.
