摘要
根据相关的基本概念,从量纲分析和思想实验的角度介绍了光速的起源,并指出了超光速的不可能性。深入探讨了光量子和量子态等概念的内涵。基于光子分裂的视角,分析了基于量子态表达二进制数据的物理实质,提出了可控的光子分裂的概念。可控的光子分裂是实现二进制数据量子态表达的前提。讨论了量子通信的现有理论基础可能会面临的问题。
According to relevant basic concepts, the origin of the speed of light is presented from the point of dimensional analysis and thought experiment. The impossibility of faster-than-light is pointed out. The connotation of the concepts such as light quantum, quantum state, etc. is discussed in depth. On the basis of the view of photon splitting, the physical essence of quantum state representation of binary data is analyzed and the concept of controllable photon splitting is proposed. Controllable photon splitting is the precondition for realizing quantum state representation of binary data. The problems which the existing theoretical basis of quantum communication may face are discussed.
