摘要：
A brief review of nonclassicality conditions in terms of moments of the creation and annihilation operators is given. By introducing k-th power amplitude squeezing, the notions of ordinary quadrature squeezing and amplitude-squared squeezing are generalized. Minimum uncertainty states are considered as a special class of k-th power amplitude squeezed states. These states can be characterized by a special, rather simple nonclassicality condition.
