    "abstract": "A closed system of the equations for the local Bloch vectors and spin\ncorrelation functions is obtained by decomplexification of the Liouville-von\nNeumann equation for three magnetic qubits with the exchange interaction, that\ntakes place in an arbitrary time-dependent external magnetic field. The\nnumerical comparative analysis of entanglement is carried out depending on\ninitial conditions and the magnetic field modulation. The present study may be\nuseful for analysis of interference experiments and in the field of quantum\ncomputing.",
