摘　　要：Photon quantum statistics of light can be shown by the high-order coherence. The fourth-order coherences of various quantum states including Fock states, coherent states, thermal states and squeezed vacuum states are investigated based on a double Hanbury Brown Twiss （HBT） scheme. The analytical results are obtained by taking the overall efficiency and background into account.Photon quantum statistics of light can be shown by the high-order coherence.
