Abstract
Recently, Sang and Nie (Int. J. Theor. Phys. 10, 1007 2017), proposed a protocol of deterministic tripartite controlled remote state preparation via a seven-qubit entangled state as quantum channel. In this paper, we present a novel scheme for tripartite controlled remote state preparation via a seven-qubit entangled state and three auxiliary particles. Our program is proposed by selecting a new set of measurement bases to enhance the implementation of scheme, and it is more perfect and efficient than the previous ones.
