Summary
For the first time, a four-photon Greenberger-Horne-Zeilinger state is generated with a fidelity of 98%, which is even comparable to the best fidelity of biphoton entangled states, and enables us to demonstrate an ultrahigh-fidelity entanglement swapping-the key ingredient in various quantum information tasks.
