Advances on continuous-variable quantum teleportation
Quantum teleportation is one of the most important protocols in the field of quantum information.By utilizing quantum entanglement,quantum teleportation serves as a key element of quantum technologies and a cornerstone across many quantum information tasks.It also plays a key role in the development of quantum communication,quantum computation,and quantum networks.Quantum teleportation with continuous variable systems attracted great attention and grows very fast due to the infinite-dimensional Hilbert space and deterministic in experiment.In this paper,we summarize the basic theory of continuous variable quantum teleportation and its research progress,particularly we focus on its experimental realization.We outline the different development paths of continuous variable quantum teleportation in terms of fidelity improvement,teleportation of different quantum states,and channel multiplexing teleportation schemes.By reviewing the research progress of teleportation,this paper further explores its future prospects and challenges.
