# Quantum suprematism picture of Malevich's squares triada for spin states and the parametric oscillator evolution in the probability representation of quantum mechanics. (arXiv:1712.01927v1 [quant-ph])

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.
