Abstract: | In this paper, we present a peculiar
tripartite entangled state that is
inequivalent to both the GHZ state and the W state, and then propose to
implement efficient quantum information processing such as quantum dense
coding and teleportation with this entangled state in cavity QED. In this
scheme the atoms interact with a highly detuned cavity field with the
assistance of a strong classical driven field. It does not require the
transfer of quantum information between the atomic system and the cavity,
and then our scheme is insensitive to both the cavity decay and the thermal field. |
