Abstract
Controlled quantum teleportation(CQT),which is regarded as the prelude and backbone for a genuine quantum internet,reveals the cooperation,supervision,and control relationship among the sender,receiver,and controller in the quantum network within the simplest unit.Compared with low-dimensional counterparts,high-dimensional CQT can exhibit larger information trans-mission capacity and higher superiority of the controller's authority.In this article,we report a proof-of-principle experimental realization of three-dimensional(3D)CQT with a fidelity of 97.4％±0.2％.To reduce the complexity of the circuit,we simu-late a standard 4-qutrit CQT protocol in a 9x9-dimensional two-photon system with high-quality operations.The corresponding control powers are 48.1％±0.2％for teleporting a qutrit and 52.8％±0.3％for teleporting a qubit in the experiment,which are both higher than the theoretical value of control power in 2-dimensional CQT protocol(33％).The results fully demonstrate the advantages of high-dimensional multi-partite entangled networks and provide new avenues for constructing complex quantum networks.
