Essentially entangled component of multipartite mixed quantum states, its properties, and an efficient algorithm for its extraction
Using geometric means, we first consider a density matrix decomposition of a multipartite quantum system of a finite dimension into two density matrices: a separable one, also known as the best separable approximation, and an essentially entangled one, which contains no product state components. We show that this convex decomposition …
