Entanglement swapping is utilized to establish entanglement between non-adjacent quantum nodes, for hop by hop mechanism is impossible because of the non-cloning theorem. Noted that every time quantum teleportation is conducted, the pre-shared entanglement will be collapsed, or say, consumed. Therefore, the 3 main challenges of remote entanglement distributions are: limited resources, severe decoherence and low success rate, where the latter two factors even aggravate the shortage of resources.
