Recently, the delayed-choice quantum eraser has been applied for coherently excited superresolution using phase-controlled projection measurements of laser light to overcome the diffraction limit in classical physics as well as to solve the limited order N of the N00N state in quantum physics. Here, a general scheme of the phase-controlled quantum eraser-based superresolution is proposed for quantum sensing satisfying the Heisenberg limit, and its general solution is derived for an arbitrary Nth-order intensity correlation. Furthermore, phase quantization of the proposed superresolution is discussed to better understand the wave nature of quantum mechanics. Unlike other methods of superresolution in quantum sensing, the proposed method is for the intensity products between phase-controlled quantum erasers and thus is compatible with most conventional sensing metrologies.
最近，延迟选择量子擦除器已被应用于利用激光的相位控制投影测量进行相干激发超分辨率，以克服经典物理学中的衍射极限，并解决量子物理学中N00N态的有限阶数N。在此，提出了一种基于相位控制量子擦除器的超分辨率通用方案，用于满足海森堡极限的量子传感，并针对任意第N阶强度关联推导了其通解。此外，还讨论了所提出超分辨率的相位量化，以更好地理解量子力学的波动性质。与量子传感中的其他超分辨率方法不同，所提出的方法适用于相位控制量子擦除器之间的强度乘积，因此与大多数传统传感计量学兼容。
