位相失真或像差会对光学成像系统的性能产生负面影响。通过使用位置动量纠缠光子，我们通过有意地在另一个光子的光路中引入互补像差来非局部地校正一个光子的光路中的像差。特别地，我们展示了光子横向自由度中奇数和偶数阶像差的同时非局域消除。我们还展示了这一技术的潜在应用，通过在量子成像实验中非局部抵消散焦的影响，从而恢复原始的空间分辨率。
Phase distortions, or aberrations, can negatively influence the performance of an optical imaging system. Through the use of position-momentum entangled photons, we nonlocally correct for aberrations in one photon’s optical path by intentionally introducing the complementary aberrations in the optical path of the other photon. In particular, we demonstrate the simultaneous nonlocal cancellation of aberrations that are of both even and odd order in the photons’ transverse degrees of freedom. We also demonstrate a potential application of this technique by nonlocally canceling the effect of defocus in a quantum imaging experiment and thereby recover the original spatial resolution.
