论文摘要
量子纠缠是许多应用程序的关键，例如量子钥匙分布，量子传送和量子传感。但是，可靠地在宏观系统中产生量子纠缠已被证明是一个挑战。在这里，我们提供了对Ponderomotive纠缠产生的详细分析，该分析利用光学机械相互作用来创建量子相关。我们从数值上计算纠缠措施 - 对数负性 - 用于纠缠的定量评估。计算中包括了现有实验的测量结果，包括热噪声和光损失，包括热噪声和光损失，这是在分析上解决的棘手。这项工作将在蓬勃发展纠缠设备的开发中发挥重要作用。
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.
