Query: Optimal unbiased state characterization   We propose a general approach to characterize states of a bipartite system
composed by a fully controllable and an unaccessible subsystems. The method is
based on the measuring interference between states of the uncontrollable
subsystem obtained after projecting an appropriately transformed bipartite
state on the basis of the accessible subsystem by local operations.
