According quantum information, a physical meaning has not only the square of the modulus of wave function, but the wave function itself. Two ways to describe a physical object exist: from the object to the whole (i.e. as moving object in space time, from the whole to the object (i.e. as a concrete asymmetry of a fractal structure representing the whole).. Wave function represents such a concrete asym-metry of a fractal structure in space-time. Physical quantity representing a linear and Hermitian operator in Hilbert space means some move-ment of an object in space-time expressed by means of a change of its definitive asymmetry with regards to the whole. The being of the physical quantity is information.
