Description
In this short note we discuss the relation between the so-called Off-Diagonal-Long-Range-Order in many-body interacting quantum systems introduced by C. N. Yang in Rev. Mod. Phys. {\bf 34}, 694 (1962) and entanglement. We argue that there is a direct relation between these two concepts.
