Enhancement of nonclassical effect and superposition state
Zhanxian Yan, Kaicheng Zhu, Qing Wang · Journal of the Optical Society of America B · 1992
The quantum statistical properties of the superposition state involving a coherent state and a squeezed vacuum are investigated. Such states can enhance the squeezing parameter and the intensity compared with the incoming squeezed vacuum state. Also, the antibunching effect can occur in such states under certain conditions.
