Deterministic Quantum Controlled Teleportation of Arbitrary Multi-qubit States via Partially Entangled States.

In this paper, an efficient proposal for quantum controlled teleporatation of arbitrary multi-qubit states is presented via three-qubit non-maximally entangled states. The successful probability is viewed as one of the most important performance parameters for quantum teleportation. The significant advantage of our scheme is that the successful probability is independent of the coefficients of partially entangled states, and is always equal to 100% in spite of using non-maximally quantum channel. From the concrete implementation processes of this proposal, it could be found that only the usual Bell-state measurement, simple single-qubit projective measurement and common single-qubit local unitary operations, of which the physical realization has been widely explored, need to be performed without the introduction of auxiliary particles.
