机械运动中宏观或介观物体的量子纠缠的产生通常受到其环境所施加的热波动的限制。在这里，我们提出了一种在腔体的两个机械振荡镜之间建立静止纠缠的方案。研究表明，通过将宽带压缩激光用作腔体的压缩真空储存器，可以在机械镜之间产生稳定的纠缠。利用绝热消除法和主方程方法，我们分析发现，产生的纠缠本质上是由机械镜相对动量的挤压决定的，该相对动量是从挤压的储层通过腔传递的。数值验证表明我们的方案符合光力学技术目前的实验水平。
The generation of quantum entanglement of macroscopic or mesoscopic bodies in mechanical motion is generally bounded by the thermal fluctuation exerted by their environments. Here we propose a scheme to establish stationary entanglement between two mechanically oscillating mirrors of a cavity. It is revealed that, by applying a broadband squeezed laser acting as a squeezed-vacuum reservoir to the cavity, a stable entanglement between the mechanical mirrors can be generated. Using the adiabatic elimination and master equation methods, we analytically find that the generated entanglement is essentially determined by the squeezing of the relative momentum of the mechanical mirrors, which is transferred from the squeezed reservoir through the cavity. Numerical verification indicates that our scheme is within the present experimental state of the art of optomechanics.
