Abstract
AbstractIn the 40 years since the BB84 protocol was proposed, the practical progress of quantum communication has been relatively slow, because many key technologies have not yet made breakthroughs. This paper proposes a model that can be supported by existing technologies, that is, three-non quantum communication which has no quantum key distribution, no teleportation, and no information transmission. Its working principle is that Alice uses fiber channel or free space to send polarized entangled photon streams to Bob and has the controllable decoherence of entangled photons with the industrial-grade optoelectronic devices, and her control role is equivalent to information coding to realize communication functions. It also has other characteristics such as no requirement for code rate, single-photon detection, quantum base operations and classical channel, etc. It has a low requirement for light sources and transmission channels and is easy to implement.
