Bipartite

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, $H\_A\; \backslash otimes\; H\_B$. State vectors and [[density operator]]s on $H\_A\; \backslash otimes\; H\_B$ are called ''bipartite quantum states''. == See also == * [[ Multipartite ]] * [[ Tensor product ]] * [[ Bipartite states and Schmidt decomposition ]] == External links == * [http://en.wiktionary.org/wiki/bipartite Bipartite] in Wiktionary [[Category:Handbook of Quantum Information]] [[Category:Mathematical Structure]]
