Undetermined terminal-based accelerated joint quantum remote state preparation method

An undetermined terminal-based accelerated joint quantum remote state preparation method performed by a sending terminal, comprising:

• determining chain channels between at least two sending terminals and a receiving terminal edge node;
• and
• jointly preparing, by the at least two sending terminals that share to-be-transferred information together, the to-be-transferred information for the receiving terminal edge node together, sending, by the receiving terminal edge node, the to-be-transferred information to a plurality of candidate receiving terminals, and after a target receiving terminal is determined, recovering, by the other candidate receiving terminals and the target receiving terminal, the to-be-transferred information shared together by the at least two sending terminals,
• wherein the jointly preparing, by the at least two sending terminals that share to-be-transferred information together, the to-be-transferred information for the receiving terminal edge node together, sending, by the receiving terminal edge node, the to-be-transferred information to a plurality of candidate receiving terminals, comprises:
• introducing an auxiliary particle |0b into one of the sending terminals, performing a CNOT operation on particles (1, b), and sending the auxiliary particle |0b to the other sending terminal;
• and
• separately selecting, by the at least two sending terminals, corresponding amplitude measurement bases and phase measurement bases according to a part of the to-be-transferred information shared by the at least two sending terminals, and jointly preparing the to-be-transferred information for the receiving terminal edge node together.
