针对诱导相干量子成像易受噪声影响的问题，提出基于信号干涉调制的成像蒸馏方法，实验证明其可在噪声高达信号250倍时生成高质量图像。

摘要：

基于诱导相干效应的成像利用光子对来获取物体信息，而无需探测照射该物体的光。当一个光子照射物体时，只有其伙伴光子被探测，因此不需要测量符合事件。通过观察被探测光子上的某种干涉图样，即可揭示所寻求的物体信息。在此，我们通过实验证明，这种成像技术可以具备抗噪声能力。我们引入了一种基于对感兴趣信号进行干涉调制的成像蒸馏方法。结果表明，即使在噪声水平高达实际感兴趣信号250倍的情况下，我们的方案仍能生成高质量的物体图像。我们还对研究结果给出了详细的理论解释。

英文摘要：

Imaging based on the induced coherence effect makes use of photon pairs to obtain information of an object without detecting the light that probes it. While one photon illuminates the object, only its partner is detected, so no measurement of coincidence events are needed. The sought-after object's information is revealed observing a certain interference pattern on the detected photon. Here we demonstrate experimentally that this imaging technique can be made resilient to noise. We introduce an imaging distillation approach based on the interferometric modulation of the signal of interest. We show that our scheme can generate a high-quality image of an object even against noise levels up to 250 times the actual signal of interest. We also include a detailed theoretical explanation of our findings.
