We report the experimental manipulation of five-photon entanglement. In the experiment, we first generate a high intensity and ultra-stable source of entangled photons and then used two pairs of entangled photons to produce a four-photon entangled state. After combining it with a single-photon state, we are able to engineer a five-photon entangled state. Meanwhile, by manipulating these entangled states, we have also successfully demonstrated the open-destination quantum teleportation, and a distant nondestructive Controlled-NOT gate for quantum teleportation.
