Preparation of Three-atom Entangled W StateVia Resonant Atom-field Interaction
Shao-Hua Xiang · Acta Sinica Quantum Optica · 2002
We present a simple and realizable scheme to generate three-atom entangled W state, based on the resonant interaction of three two-level atoms with one single-mode cavity field. It is shown that such state can easily be achieved by controlling the interaction time of atom-cavity-field and the coupling constant without the detection of photon number within the cavity. In addition, the experimental feasibility within the realm of cavity QED is analyzed.
