The Progress and the state-of-art approaches of Quantum Teleportation and Communication

Abstract

Quantum teleportation is a new technique utilized dispersed quantum entanglement to transmit information (i.e., the quantum states). In this paper, the principles and the protocol will be introduced systematically. Specifically, the experimental setups and the state-of-art applications will be discussed. According to the analysis, one can better understand the working principle and current development of quantum teleportation. However, the limitation of further applying the quantum teleportation is obvious the cost of building the QT infrastructure and the superconducting technology. Besides, it is also too expensive to achieve large-scale use and commercial promotion. In the future, QT will expand its industrial scale and build a national or even global quantum communication network. These results shed light on guiding further development for quantum teleportation important.
