Quantum information splitting of an arbitrary three-atom state by using W-class states in cavity QED. (English) Zbl 1247.81070
Summary: We demonstrate that four sets of W-class states can be used to realize the deterministic quantum information splitting of an arbitrary three-atom state in cavity QED. The scheme does not involve Bell-state measurement and is insensitive to both the cavity decay and the thermal field.
