论文摘要
过去,已经提出了几种量子加密方案并实验实现。但是,即使在量子技术方面有所进步,并升级了对直接安全量子通信方案设计的兴趣,这些加密方案也没有太多的实验实现。在本文中,我们为此类量子加密方案提供了一组光电电路,尚未通过修改我们的一些理论上提出的安全通信方案来实验实现。具体来说,我们提出了用于实施两个单个光子和一个基于状态的控制量子对话方案的光学设计,并随后降低了我们的光学设计,以产生更简单的设计,以实现其他安全的量子通信任务,即,受控的确定性确定性安全量子通信,量子安全的直接通信,量子直接通信,量子键键,量子键分配和量子键分配。我们进一步提出了一种基于纠缠交换的确定性安全量子通信及其受控对应物的光学设计。
Several quantum cryptographic schemes have been proposed and realized experimentally in the past. However, even with an advancement in quantum technology and escalated interest in the designing of direct secure quantum communication schemes there are not many experimental implementations of these cryptographic schemes. In this paper, we have provided a set of optical circuits for such quantum cryptographic schemes, which have not yet been realized experimentally by modifying some of our theoretically proposed secure communication schemes. Specifically, we have proposed optical designs for the implementation of two single photon and one entangled state based controlled quantum dialogue schemes and subsequently reduced our optical designs to yield simpler designs for realizing other secure quantum communication tasks, i.e., controlled deterministic secure quantum communication, quantum dialogue, quantum secure direct communication, quantum key agreement, and quantum key distribution. We have further proposed an optical design for an entanglement swapping based deterministic secure quantum communication and its controlled counterpart.
