Work on two kinds of nonclassical states is proposed. The first are states whose phase is correlated with their ampli- tude. States of this kind can be detected by measuring their noise after they have passed through a Kerr medium. The objective is to develop a formalism for describing the phase/amplitude correlations for such states. The second set of states to be studied are the so called squeezed states. In particular, those states which are squeezed in the mode ampli- tudes (quadratic squeezing). Three basic forms of quadratic squeezing have already been examined and it is proposed to study the nature of mixed forms of these states. Here, non-linear interactions can transform different types of quadratically squeezed states among themselves. These trans- formations will be studied in some detail in the proposal.

提出了关于两种非经典状态的工作。第一种是相位与其振幅相关的状态。 这种状态可以通过测量它们通过克尔介质后的噪声来检测。目标是开发一种形式来描述此类状态的相位/幅度相关性。要研究的第二组状态是所谓的压缩状态。特别是那些模幅被压缩的状态（二次压缩）。二次挤压的三种基本形式已经被研究过，并且建议研究这些状态的混合形式的性质。在这里，非线性相互作用可以在它们之间转换不同类型的二次压缩状态。该提案将详细研究这些转变。
