Controlled quantum teleportation with Bell states
Tian‐Yin Wang, Qiaoyan Wen · Chinese Physics B · 2011
We propose a new scheme for controlled quantum teleportation with Bell states in which classical keys for controllers' portion are used. We also discuss the security of the proposed scheme and show that it can satisfy the requirements for controlled quantum teleportation. The comparison between this scheme and the previous ones shows that it is more economical and efficient.
