Abstract
Two-particle spin states are considered. The problem of reconstruction of the density matrix of the states in terms of the measurement data is studied. Two methods of such reconstruction are investigated — one is connected with reduction of the density matrix and the other is based on the quantum-tomography approach; the number of measurements needed in each case is obtained.
