标题： Hectometer Revivals of Quantum Interference

摘要： 腔增强的单光子源表现出具有梳状相关函数的锁模双光子态。 我们的超亮光源另外发射单光子对或两光子NOON态，分别将输出分为偶数梳和奇数梳。 利用偶数梳光子，我们展示了典型的非经典Hong-Ou-Mandel干涉的复兴，直至第84个凹陷，对应于路径长度差超过100米。 利用奇数梳光子，我们观察到单光子干涉条纹在Hong-Ou-Mandel干涉的位移范围的两倍内被调制。 显示英文摘要

摘要： Cavity-enhanced single photon sources exhibit mode-locked biphoton states with comb-like correlation functions. Our ultrabright source additionally emits either single photon pairs or two-photon NOON states, dividing the output into an even and an odd comb respectively. With even-comb photons we demonstrate revivals of the typical non-classical Hong-Ou-Mandel interference up to the 84th dip, corresponding to a path length difference exceeding 100 m. With odd-comb photons we observe single photon interference fringes modulated over twice the displacement range of the Hong-Ou-Mandel interference.
