The invention provides an undetermined terminal-based accelerated joint quantum remote state preparation method, including: determining chain channels between at least two sending terminals and a receiving terminal edge node, and determining GHZ channels between the receiving terminal edge node and a plurality of candidate receiving terminals; jointly preparing, by the at least two sending terminals together, to-be-transferred information for the receiving terminal edge node; and sending, by the receiving terminal edge node, the to-be-transferred information to the plurality of candidate receiving terminals, after a target receiving terminal is determined, performing, by the other candidate receiving terminals, a measurement operation, and performing, by the target receiving terminal, corresponding unitary transformation to recover the to-be-transferred information. Information transfer efficiency and information security are greatly improved, thereby resolving a current problem that a terminal lacks a scheme of remotely preparing a quantum state in a case that a receiving terminal is indefinite.
