The coherent state is represented by a minimum uncertainty wave packet , the quantum correlation in these state is absent , so that it behaves as a quasi - classical state . it is such a property that leads to the results coincide completely with those obtained in semiclassical approximation 正是因為相干態是一個量子力學允許的最小的測不準波包，沒有任何量子關聯，可以看作是一個準經典態，才導致了完全量子場論和半經典近似下理論結果的完全一致性。
Generally , the electron and photons become entangled as the electronic wave packet evolves . if initial photon state is a coherent state and we neglected the transferred photons then the quantized - field calculation is equivalent to the semiclassical calculation 當初始光子態是相干態，且忽略轉移的光子數時，電子與量子場系統之間不存在相關性，這種情況下量子場計算與半經典計算等價；當初始光子態是f 。
