Original Abstract Submitted
the present invention discloses a high-fidelity entangled link generation method based on quantum time-space, the method comprising: directing, by a communication provider, a laser beam to a nonlinear crystal, thereby enabling probabilistically bursting out of a photon beam, and polarizing the photon beam to be in an entangled state; at an entanglement distribution stage, enabling entangled photons to traverse through quantum trajectories, and generating a distributed entangled photon state between a first communication node and a second communication node to construct an elementary entangled link; the first communication node or the second communication node is required to select the same measurement basis for m control qubits when m copies of entangled photon pairs from entanglement source are assumed to be distributed through quantum trajectories to communication nodes with the time interval �, such that 2 m memory qubits of two adjacent nodes may store m exactly the same distributed entangled states.
