符合成像是当两个系统被具有适当相关性的源照射时，从由参考系统透射的光子的统计中提取测试系统的图像的技术。最近有人认为，量子纠缠源是必要的实施这项技术。我们表明，这种技术不需要纠缠，我们提供了一个实验演示的符合成像使用经典源。我们进一步发现，任何一种符合成像技术，它使用一个“桶”检测器的测试臂是无法成像的相位只有对象，无论是采用经典或量子源。
Coincidence imaging is a technique that extracts an image of a test system from the statistics of photons transmitted by a reference system when the two systems are illuminated by a source possessing appropriate correlations. It has recently been argued that quantum entangled sources are necessary for the implementation of this technique. We show that this technique does not require entanglement, and we provide an experimental demonstration of coincidence imaging using a classical source. We further find that any kind of coincidence imaging technique which uses a "bucket" detector in the test arm is incapable of imaging phase-only objects, whether a classical or quantum source is employed.
