We solve the joint open problems of photon localization and single-photon wave functions in the context of spontaneous emission from an excited atom in free space. Our wave functions are well-defined members of a discrete orthonormal function set. Both the degree and shape of the localization are controlled by entanglement mapping onto the atom wave function, even though the atom is remote from the photon.
我们在自由空间中激发原子自发辐射的背景下，解决了光子定位和单光子波函数的联合开放问题。我们的波函数是离散正交归一函数集的明确定义的成员。尽管原子与光子相距甚远，但定位的程度和形状都由映射到原子波函数上的纠缠控制。
