Title: Controlled cyclic quantum teleportation of an arbitrary qubit state from 4 participants via a nine-qubit entangled
Abstract: We proposed a scheme of teleported arbitrary four-qubit states from four participants cyclically. In this scheme, Alice sends an arbitrary qubit state to Bob. Bob sends an arbitrary qubit to Charli. At the same time, Charli sends his arbitrary qubit state to David while David sends his arbitrary qubit state to Alice. The teleportation scheme is carried out cyclically via a nine-qubit entangled channel with Eve’s assistance as a controller and Bell’s measurements.
