论文摘要
我们量化了由固定镜组成的环腔的光学模式与相对机械模式之间的固定相关性，并在三角形设计中进行了两个可移动的镜子。两分协方差矩阵用于评估对数负性，以衡量纠缠的量度，高斯量子不和谐，作为量度的总量子相关性和互信息，作为整体相关性的度量。讨论了这些量相对于环境温度以及其他参数的行为，例如激光抽水功率和可移动镜的质量。
We quantify the stationary correlations between the optical mode and the relative mechanical mode of a ring cavity composed of a fixed mirror and two movable ones in a triangular design. The bipartite covariance matrix, is used to evaluate the logarithmic negativity as a measure of entanglement, the Gaussian quantum discord as a measure of total quantum correlations and the mutual information as a measure of the overall correlations. The behaviour of these quantities with respect to the environment's temperature as well as other parameters such as the laser pumping power and mass of the movable mirrors is discussed.
