Fisher information and quantum squeezing properties of Gaussian pure states

摘要：

　　In this paper the Fisher information of Gaussian pure States is studied.Based on the definition of joint non-classical properties,we calculate the non-classical properties of Gaussian pure States.The results show that the Fisher information and Fisher length are efficacious tools to study the non-classical properties of quantum States.
