用量子理论方法给出两光子的自旋态，即通过2个单光子自旋态的直积并叠加得到两光子的自旋本征态，从而给出两光子的纠缠态，所得结果与用经典极化矢量表示的两光子纠缠态不同，该结果可应用于量子通讯和量子计算中。

We gave the spin states of two-photon using quantum theory approach,i.e.,two-photon spin eigen states were expressed by the superposition of the direct product of two single photon spin states.Then,we obtained the quantum representation of two-photon entanglement states,which are different from the classical polarization vector expression of two-photon entanglement state.The results could be used in quantum communication and quantum computation.
