The Development and Application of Quantum Teleportation
Hao Chen
Abstract
Quantum teleportation is one of the most important protocols in quantum information, which is based on quantum entanglement. This paper provides an overview of the basic theory behind the original quantum teleportation protocol and explores its advanced variations. We validate these protocols' effectiveness by constructing simple quantum circuits. Following this, we delve into deeper theoretical aspects, experimental realizations, and applications of quantum teleportation, including quantum state exchange experiments and weak measurement techniques, as well as environment-assisted measurements. Finally, we briefly discussed its current limitations and the future prospects of quantum teleportation.
