Something is said to bipartite if it consists of two distinct parts.

In quantum information science it is often quantum systems that are shared between two parties, usually spatially separated and called Alice and Bob.

If Alice's subsystem is described by the Hilbert space H_A and Bob's is described by H_B, the compound bipartite system is described by the tensor product of the two spaces, H_A ⊗ H_B. State vectors and density operators on H_A ⊗ H_B are called bipartite quantum states.
