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.
Is proposed numerical method for simulation reconstruction quantum states of light's harmonics in homodyne tomography. Had been investigated the homodyne processing of discretized and quantized function of sine that was used as model of light's harmonic. In results were obtained the representations of the squeezed quantum amplitude-phase and vacuum states, as well as vacuum and coherent (displaced) quantum states. The computing simulation model parameters have been identified, and estimated. Graphics images of quantum states are presented; future using of obtained results for quantum tomography are discussed.
