| Popis: | How far is the distance between the two is obtained through mutually entangled particles. A far as long as the state of one particle changes, so as the state of the other particle instantaneously change. We present a scheme for hierarchical quantum teleportation via a four-qubit cluster state, where a sender distributes asymmetrically a quantum state to distant agents. This asymmetrically distribution leads to different agents to have different authority to reconstruct the secret quantum information. Furthermore, the hierarchical quantum teleportation of an arbitrary single-qubit state can be realized in cavity quantum electrodynamics (QED) systems. |
