Deterministic Quantum-Controlled Teleportation of Arbitrary Multi-Qubit States Via Three-Qubit Entangled States

Abstract. In this paper, we propose an efficient proposal of quantum-controlled teleportation for transmitting arbitrary multi-qubit states via maximally three-qubit entangled states, in which the sender transmits arbitrary multi-qubit states to the remote receiver under control of the supervisor. This proposal is performed with 100% successful probability by using only Bell-state mutually orthogonal measurement basis and single-qubit measurement basis without the introduction of auxiliary particle. The concrete implementation process is given in detail and the total classical information cost required in the process of this proposal is also calculated.
