摘要

我们通过对倒置振荡器应用运动积分法,确定了该系统几种重要的非经典状态的演化概率表示。最初在谐波振荡器势中准备的非经典状态包括偶数和奇数薛定谔猫态、挤压相干态和相干态的晶格叠加。后一种叠加可以高精度地逼近几种非经典态,因此它们的概率表示可以描述反相振荡器的各种非经典态。通过确定出现在概率表示中的叠加参数,显示了数态、光子数叠加和振幅挤压态的近似结果。

Probability Representation of Nonclassical States of the Inverted Oscillator

We determine the evolving probability representations of several important nonclassical states of the inverted oscillator by applying the method of integrals of motion for this system. The considered nonclassical states initially prepared in the potential of the harmonic oscillator are even and odd Schrödinger cat states, squeezed coherent states, and lattice superpositions of coherent states. The latter superpositions can approximate several nonclassical states with high precision, hence their probability representation can describe various nonclassical states of the inverted oscillators. Explicit results are shown for the approximation of number states, photon number superpositions, and amplitude squeezed states by determining the parameters of the superposition appearing in the probability
