Experimental Analysis of a 4-Qubit Cluster State
Nikolai Kiesel, Christian Schmid, Ulrich Weber +4
Linear optics quantum logic operations enabled the observation of a four-photon cluster state. We prove genuine four-partite entanglement and study its persistency, demonstrating r…

Linear Optics C-Phase gate made simple
Nikolai Kiesel, Christian Schmid, Ulrich Weber +2
Linear optics quantum logic gates are the best tool to generate multi-photon entanglement. Simplifying a recent approach [Phys. Rev. A 65, 062324; Phys. Rev. A 66, 024308] we were…
