We study mode entanglement in four quantum states (coherent state, squeezed vacuum state, displaced squeezed state, squeezed coherent state), which are generated from a bosonic two-mode vacuum state by the action of displacement and squeezing operators. The mode entanglement entropy in these states is calculated and shown to depend only on the squeezing magnitude.
