摘要：
A scheme of two-way teleportation is proposed, with Bell entangled state as Quantum Channel (QC). Firstly, two sides of communication(Alice and Bob), share two EPR entangled states. After communication, Alice and Bob perform Bell-state joint measurements to their own qubits respectively, and announce the measured results via Classical Channel (CC). Then according to the measured results, Alice and Bob make relevant unitary transformations, namely, its own party can reproduce the opposite quantum state information, and thus the two-way teleportation is realized. In order to enhance the security of two-way teleportation, and the analysis result indicates that the system's security will strengthen with the increase of the control particles, but the security will not strengthen when the control particles increase to a certain number.
