    "abstract": "We propose a method for the tomographic reconstruction of qubit states for a\ngeneral class of solid state systems in which the Hamiltonians are represented\nby spin operators, e.g., with Heisenberg-, $XXZ$-, or XY- type exchange\ninteractions. We analyze the implementation of the projective operator\nmeasurements, or spin measurements, on qubit states. All the qubit states for\nthe spin Hamiltonians can be reconstructed by using experimental data.",
