In quantum information, photons possess the advantage of weak interactions with the environment but also a disadvantage in that it is difficult to perform any non-linear operation on them. Thus, a Gaussian (quasi-classical) field will stay Gaussian most of time. However, non-linear interactions between the mechanical oscillator and optical cavity in an optomechanical system permit a non-classical evolution of the cavity field in the fourth and higher orders of expansion. In this project a bi-chromatic driving with a phase change after each mechanical period will be used to eliminate most optical and interaction terms in lower orders of expansion, allowing the non-classicality and purity of the resulting cavity field to be investigated.

在量子信息中，光子具有与环境相互作用弱的优点，但也有缺点，即很难对它们进行任何非线性操作。因此，高斯场(准经典)大部分时间将保持高斯场。然而，在光学机械系统中，机械振子和光腔之间的非线性相互作用允许腔场在四阶和更高阶展开中的非经典演化。在这个项目中，在每个机械周期之后的相变的双色驱动将被用来消除较低级展开中的大部分光学项和相互作用项，从而允许研究所产生的腔场的非经典和纯度。
