Abstract: | We discuss the generation of certain kinds of multi-component
entangled states for three-level atomic system with hyperfine structure.
The method proposed here is based on the interactions of dispersive
cavity with only one atom driven by a strong classical field.
It is shown that, with a judicious choice of the cavity detuning
and applied coherent field detuning, the atom can interact dispersively
with the quantized field but the classical driving field gives rise
to the creation or destruction of photons conditional on the state of
the system. In comparison with previous schemes,
our method is likely to be extremely easy to realize in practice. |
