摘要：

Quantum dense coding via a two-mode squeezed-vacuum state is proposed, where classical information is encoded in two quadrature components of one mode of a two-mode squeezed-vacuum state. Decoding at a receiver side is performed by simultaneous measurement of two quadrature components of the two-mode state. Since a two-mode squeezed-vacuum state is partially entangled, the information can only be transmitted without error in the strong-squeezing limit.
