| 摘 要： | This paper reports that a quantum dense coding can be implemented with ions confined in a linear trap and interacting with laser beams. The scheme is insensitive to the interaction between the quantum channel and the environment. The Bell-state measurement is not involved and the probability of success in our scheme is 1.0.

| Abstract: | This paper reports that a quantum dense coding can be implemented
with ions confined in a linear trap and interacting with laser
beams. The scheme is insensitive to the interaction between the
quantum channel and the environment. The Bell-state measurement is
not involved and the probability of success in our scheme is $1.0$. |
