Experimental observation of an entire family of four-photon entangled states
arXiv:0806.1882 · doi:10.1103/PhysRevLett.101.010503
Abstract
A single linear optical set-up is used to observe an entire family of four-photon entangled states. This approach breaks with the inflexibility of present linear-optical set-ups usually designed for the observation of a particular multi-partite entangled state only. The family includes several prominent entangled states that are known to be highly relevant for quantum information applications.
