D-dimensional chain type invisible state transfer method based on random sending of relay node measurement result

The invention discloses a d-dimensional chain type invisible state transfer method based on random sending of a relay node measurement result. The d-dimensional chain type invisible state transfer method based on random sending of the relay node measurement result comprises the steps that two communication parties are an information sender Alice and an information receiver Bob, and particles t carry unknown quantum states and are held by the information sender Alice. Alice holds a particle t and a particle A1, wherein the first intermediate node Charlie1 holds particles B1 and A2, the second intermediate node Charlie2 holds particles B2 and A3,..., and the kth intermediate node Charliek (k = 1, 2, 3,..., P) holds particles Bk and particles Ak + 1. The d-dimensional chain type invisible state transfer method based on random sending of the relay node measurement result has the advantages that any relay node can randomly send the generalized Bell measurement result of itself to an information sender Alice or an
