Description

The issue of evidence of a quantum system to be an elementary or a composite one is discussed within the Stratonovich-Weyl correspondence for finite dimensional systems.

The numerical experiments with a 4-level quantum system are performed in order to understand how its virtual 2-level subsystems manifest themselves in the properties of the Wigner quasiprobability distributions of quantum states.

The results of our studies show that ``compositeness of a quantum system'' is encoded not only in the density matrix of quantum state but in the structure of the Stratonovich-Weyl kernels as well.
