Abstract
The present invention discloses a d-dimensional chain teleportation method for random transmission based on measurement results of relay nodes. The method includes: two communicating parties are an information sender Alice and an information receiver Bob, a particle t carries an unknown quantum state and is held by the information sender Alice, Alice holds the particle t and a particle A1, a first intermediate node Charlie 1 holds a particle B1 and a particle A2, a second intermediate node Charlie 2 holds a particle B2 and a particle A3, . . . , and a kth (k=2, 3, . . . , P) intermediate node Charlie k holds a particle Bk and a particle Ak+1. The beneficial effect of the present invention is as follows: any relay node can randomly transmit its generalized Bell measurement result to the information sender Alice or the information receiver Bob, thereby greatly reducing connection restrictions of a classical channel.
