Abstract
Based on the partial transposition criterion on entanglement of a bipartite system, a necessary and sufficient condition for inseparability of two-mode Gaussian states is established in the non-diagonal coherent-state representation. The condition only depends on four elements of the correlation matrix characterizing the state in the representation.
