Abstract
Consider a system consisting of -dimensional quantum particles and arbitrary pure state of the whole system. Suppose we simultaneously perform complete von Neumann measurements on each particle. One can ask: what is the minimal possible value of the entropy of outcomes joint probability distribution? We show that coincides with entanglement entropy for bipartite states. We compute for two sample multipartite states: the hexacode state () and determinant states (). The generalization of determinant states to the case is considered.
