Two-mode oscillator quantum states are described via coherent state superpositions. The one-complex-plane coherent-state representation is introduced as a generalization of low-dimensional coherent-state representations of single mode fields. Application to two-mode squeezed states is emphasized, because of their entangled nature and applicability for quantum communication. Continuous variable quantum teleportation is treated in this framework.
