Multi-state Quantum Teleportation via One Entanglement State

A multi-sender-controlled quantum teleportation scheme is proposedto teleport several secret quantum states from different senders toa distance receiver based on only one Einstein-Podolsky-Rosen (EPR)pair with controlled-NOT (CNOT) gates. In the present scheme, several secret single-qubit quantum states are encoded into a multi-qubit entangled quantum state. Two communication modes, i.e.,the detecting mode and the message mode, are employed so that theeavesdropping can be detected easily and the teleported message maybe recovered efficiently. It has an advantage over teleportingseveral different quantum states for one scheme run with moreefficiency than the previous quantum teleportation schemes.
