Abstract
In this paper, a new hierarchical controlled cyclic quantum teleportation scheme is proposed, which can be applied to hierarchical quantum information transmission in a variety of application scenarios. In this scheme, Charlie in the low-level position can only complete simple sending tasks under the control of Bob, while Alice in the middle-level position needs to complete ordinary sending tasks under the control of Charlie and Diana; Bob in the high-level position needs to complete important tasks sent to Charlie under the control of the controller Diana and the high-level controller Eve. Diana and Eve can be regarded as both internal middle and high-level managers as well as different external regulators. Finally, this paper also discusses the number of controllers and their control capabilities, and briefly proposes a simplified hierarchical cyclic quantum teleportation scheme, which provides more options for users with different needs.
