Quantum teleportation and its principles

Donglin Cai, Menghan Dong

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.

Recent experiments confirm that quantum teleportation is possible at least for states of photons and nuclear spins. The quantum teleportation is not only a curious effect but a fundamental protocol of quantum communication and quantum computing. The principles of the quantum teleportation and the entanglement swapping are explained, and physical realizations of teleportation of optical and atomic states are discussed.

We implement a quantum teleportation algorithm in NMR with 13 C-labeled L -alanine. Here three 13 C-nuclear spins are qubits and H-nuclear spins are employed as a well-defined quantum mechanical interface to a detector. Our experiment is considered as a realization of “quantum teleportation without irreversible detection” and is helpful for understanding the principle of quantum teleportation.
