Abstract: | According to the protocol of Agrawal et al., we propose a cavity QED
scheme for realization of teleportation and dense coding. Instead of using EPR
states and GHZ states, our scheme is more insensitive to the loss of one
particle by using a W-class state as a quantum channel. Besides, our scheme
is immune to thermal field, and does not require the cavity to remain in the
vacuum state throughout the procedure. |
