In order to solve the problem of information acquisition of quantum state,based on the quantum tomography theory,the single-qubit and multi-qubits tomography techniques are analyzed in details and an experiment for quantum state measurement is designed.Then the practicability of this method is verified by the simulation for single-qubit tomography with computer simulation technology.Simulation results show that not only the density matrix can be reconstructed and the information of quantum state can be obtained,but also the efficiency of experiment is satisfying,when suitable measurement times are chosen in quantum tomography experiment.
