摘要：

Information transmission via the quantum dense coding of continuous variables by using a two-mode squeezed vacuum state is considered for a noisy quantum channel. It is shown that if the channel noise is not so strong, the quantum dense coding of continuous variables works well for information transmission even in a noisy quantum channel.
