  Review of tomographic probability representation of quantum states is
presented both for oscillator systems with continious variables and
spin--systems with discrete variables. New entropic--information inequalities
are obtained for Franck--Condon factors. Density matrices of qudit states are
expressed in terms of probabilities of artificial qubits as well as the quantum
suprematism approach to geometry of these states using the triadas of Malevich
squares is developed. Examples of qubits, qutrits and ququarts are considered.
