Abstract. We present examples of macroscopic systems entailing a quantum mechanical
structure. One of our examples has a structure which is isomorphic to the spin structure
for a spin 1/2 and another system entails a structure isomorphic to the structure of two spin
1/2 in the entangled singlet state. We elaborate this system by showing that an arbitrary
tensor product state representing two entangled qubits can be described in a complete way by a
specific internal constraint between the ray or density states of the two qubits, which describes
