摘要:

量子纠缠是量子密钥分发、量子隐形传态和量子传感等许多应用的关键。然而,在宏观系统中可靠地产生量子纠缠已被证明是一个挑战。在这里,我们提出了一个详细的分析有质动力纠缠的产生,利用光机相互作用,以创建量子关联。我们数值计算的纠缠措施-对数负-的纠缠的定量评估。实验的限制,包括热噪声和光损耗,从现有的实验测量包括在计算中,这是难以解决的分析。这一工作对有质动力纠缠器件的发展具有重要意义。

英文摘要:

Quantum entanglement is the key to many applications like quantum key distribution, quantum teleportation, and quantum sensing. However, reliably generating quantum entanglement in macroscopic systems has proved to be a challenge. Here, we present a detailed analysis of ponderomotive entanglement generation which utilizes optomechanical interactions to create quantum correlations. We numerically calculate an entanglement measure -- the logarithmic negativity -- for the quantitative assessment of the entanglement. Experimental limitations, including thermal noise and optical loss, from measurements of an existing experiment were included in the calculation, which is intractable to solve analytically. This work will play an important role in the development of ponderomotive entanglement devices.
