我们提出了一种双腔装置，能够在低温下产生两个可移动镜子的静止纠缠态。该方案是基于通过腔内光的辐射压力将输入光场的压缩最优转移到反射镜的机械振动模式上。我们证明了宏观纠缠的存在可以通过对两个腔的输出光的适当读出来证明。
We propose a double-cavity set-up capable of generating a stationary entangled state of two movable mirrors at cryogenic temperatures. The scheme is based on the optimal transfer of squeezing of input optical fields to mechanical vibrational modes of the mirrors, realized by the radiation pressure of the intracavity light. We show that the presence of macroscopic entanglement can be demonstrated by an appropriate readout of the output light of the two cavities.
