In this paper we show how to construct a quantum $(k, n)$ threshold scheme without the assistance of a trusted party, who generates and distributes shares among the participants. Instead, each participant chooses his private state and contributes the same to the determination of the final secret quantum state.}, identifier = {05865904}, }
