    "abstract": "Concerning state estimation, we will compare two cases. In one case we cannot\nuse the quantum correlations between samples. In the other case, we can use\nthem. In addition, under the later case, we will propose a method which\nsimultaneously measures the complex amplitude and the expected photon number\nfor the displaced thermal states.",
