On preparation of the W-states from atomic ensembles
V. N. Gorbachev, A. A. Rodichkina, A. I. Trubilko
Abstract
A scheme, where three atomic ensembles can be prepared in the states of the W-class via Raman type interaction of strong classical field and a projection measurement involved three single-photon detectors and two beamsplitters, are considered. The obtained atomic entanglement consists of the Dicke or W-states of each of the ensembles.
