摘要:

提出了一种新的三能级光量子系统的实验实现方法。我们使用双光子的偏振态来生成用于BB 84协议扩展版本的特定状态序列。我们通过实验验证了基态的正交性,并证明了它们之间轻松切换的能力。利用层析成像方法重建了产生态的密度矩阵。

英文摘要:

The novel experimental realization of three-level optical quantum systems is presented. We use the polarization state of biphotons to generate a specific sequence of states that are used in the extended version of BB84 protocol. We experimentally verify the orthogonality of the basis states and demonstrate the ability to easily switch between them. The tomography procedure is employed to reconstruct the density matrices of generated states.
