Abstract

In this contribution we group the operator basis for -dimensional Hilbert space in a way that enables us to relate bases of entangled states with single-particle mutually unbiased state bases (MUB), each in dimensionality . We utilize these sets of operators to show that an arbitrary density matrix for this -dimensional Hilbert-space system is analyzed via measurements, of which involve those entangled states that we associate with MUB of the -dimensional single-particle constituents. The number lies in the middle of the number of measurements needed for bipartite state reconstruction with two-particle MUB and those needed by single-particle MUB .
