我们提出了一个本质上纯净的单光子态和弱相干态之间的非经典干涉实验。我们的实验表明，在不使用带通滤波器的情况下，光谱纯单光子可以对来自弱相干场的光子产生高可见度（89.4{+-}0.5%）的干扰。我们的方案为未来需要非经典态光子和相干态光子之间的量子干涉的实验奠定了基础。
We present an experiment of nonclassical interference between an intrinsically pure heralded single-photon state and a weak coherent state. Our experiment demonstrates that, without the use of bandpass filters, spectrally pure single photons can have high-visibility (89.4{+-}0.5%) interference with photons from a weak coherent field. Our scheme lays the groundwork for future experiments requiring quantum interference between photons in nonclassical states and those in coherent states.
