我们介绍了损耗分束器的一个简单量子理论。当应用于描述法布里-珀罗腔时，这导致腔内算子明显的反常换易关系。我们证明了这些不熟悉的性质仍然与矢量势算子和电场算子的基本正则换向子一致。这个结果是作为应用于镜面反射系数特性的因果关系的结果推导出来的。
We introduce a simple quantum theory of the lossy beam splitter. When applied to describe a Fabry-Perot cavity this leads to apparently anomalous commutation relations for the intracavity operators. We show that these unfamiliar properties are nevertheless consistent with the fundamental canonical commutator for the vector potential and electric field operators. This result is derived as a consequence of causality as applied to the properties of mirror reflection coefficients.
