摘要
给出各种输入态和光学器件的数学表述 ,态包括单光子的空间和极化模 ,双光子的可分离态和纠缠态 ,光学器件有分束器 ,极化分束器 ,波片 .用这种表述对一些重大实验的网络进行分析和计算 ,其中有Hadamard门的实现 ,M -Z干涉仪光路分析 ,Hong -Ou -Mandel干涉仪 ,而且自然引入了Mandel新近名著OpticalCoherenceandQuantumOptics中人为添加的因子 ,还有Teleportation实验中的Bell基的测量和一些自己设计的网络 .并同时给出一些物理上的总结 .
In the linear network of optical apparatus,various kinds of inputting states(including the polarization entangled mode and the k vector mode of a single photon and dissociable and entangled state of two photons) are described by column matrices and optical apparatus(including beam splitter,polarizing beam splitter and wave plate) are described by matrices,the outputting state is easily obtained by matrix multiplication.Using this method,some important experiments,including the Hadamard gate,M Z interferometer,measurement of Bell state in quantum teleportation and Hong Ou Mantel interferometer are calculated and analyzed, in the latter case, the seemingly artificial factors elswhere appear naturally.Some projects are designed and some physical discussions are given.
