We identify classical light fields as physical examples of nonquantum entanglement. A natural measure of degree of polarization emerges from this identification, and we discuss its systematic application to any optical field, whether beamlike or not.
我们将经典光场鉴定为非量子纠缠的物理实例。这种鉴定产生了偏振度的自然度量,我们讨论了其在任何光学场中的系统应用,无论光束是否如此。
