Abstract

The tripartite W state exhibits maximal entanglement between three parties, represented as 1/sqrt(3)(|001>+|010>+|100>), and has interesting applications for quantum communication, fundamental tests of quantum mechanics, and in quantum sensing and quantum computing. We experimentally demonstrate the generation of a three-photon discrete-energy-entangled W state in optical fiber. The source relies on multiphoton-pair generation via spontaneous four-wave mixing, and post-selection. By taking advantage of constraints imposed by the SFWM process, post-selection, and the properties of the W state, we verify the state produced by this source without resorting to frequency conversion.
