一个原子穿过一个静止的光场，会给光场带来一个位置相关的相移。通过对场进行相位敏感测量，可以将原子的位置精确到远小于光的波长。现场测量导致虚拟狭缝的产生，并且可以观察到衍射和干涉现象。相位测量提供了更多的Weg信息，并使“量子擦除”实验得以实现
An atom passing through a standing light field imparrts a position-dependent phase shift to the field. By making a phase-sensitive measurement of the field, it is possible to resolve the atom's position to much less than the wavelength of the light. The field measurement results in the creation of virtual slits, and diffraction and interference phenomena may be observed. The phase measurements give welcher Weg information and enable «quantum-eraser» experiments to be realised
