摘要
We employ the EPR eigenstate representation /eta > and the operational phase operator to propose a protocol of quantum dense coding. The /eta > state provides a convenient way to realize quantum dense coding when the quantum channel is a two-mode squeezed state, because the two-mode squeezing operator has a natural representation in the < eta/ representation.
