Abstract: This paper uses a special two-particle entangled state as a quantum channel to achieve invisibility unknown arbitrary two-particle quantum state teleportation. It makes contrast with Yuan, who makes use of χ-type entangled states to achieve two any unknown quantum state teleportation scheme. The scheme uses two sub-channels and Bell-based measurements, as well as special unitary operation successfully completing message teleportation. The program uses fewer resources, and the obtained probability of an original information is 1.
