We have successfully completed the main task of our original plan in Fiscal Year (FY) 2015 and 2016. In FY2015, we constructed a fiber spectrometer to measure the spectrally resolved Hong-Ou-Mandel interference between independent photon sources (HOMI-IPS). This experiment not only can deepen our understanding of HOMI-IPS in frequency domain, but also provides an important tool to test the theoretical predictions of HOMI-IPS using spectrally engineered photon sources. This result was published in Optics Express in 2015. In FY2016, we successfully generated discrete frequency modes in a Hong-Ou-Mandel interference. These modes are equally distributed in the frequency domain, and thus have a kind of frequency comb structure, forming a type of high dimensional entangled state (qudit). This result (arXiv:1603.07887) has been submitted to some high-profile journal.All of these experiments were done at 1.5 micrometer telecom wavelength, which is most suitable for long-haul optical communications. Therefore, our technology would enable us to enhance performances in optical-fiber-based quantum communication, e.g. quantum cryptography. Moreover, the distribution of distinct entangled frequency modes may also be useful for improving quantum metrology, quantum remote synchronization, as well as fundamental tests of stronger violation of local realism at the telecom wavelength.

我们已成功完成了2015财年和2016财年原计划的主要任务。在2015财年，我们构建了一台光纤光谱仪，用于测量独立光子源之间的光谱分辨Hong-Ou-Mandel干涉（HOMI-IPS）。该实验不仅加深了我们对HOMI-IPS在频域的理解，而且为检验基于光谱工程光子源的HOMI-IPS的理论预测提供了重要工具。这一结果于2015年发表在Optics Express上。于二零一六财政年度，我们成功在Hong-Ou-Mandel干扰中产生离散频率模式。这些模在频域中均匀分布，形成一种频率梳状结构，形成一种高维纠缠态。这一结果（arXiv：1603.07887）已提交给一些高知名度的期刊。所有这些实验都是在1.5微米电信波长下完成的，这是最适合长距离光通信的波长。因此，我们的技术将使我们能够提高基于光纤的量子通信的性能，例如量子密码学。此外，不同的纠缠频率模式的分布也可能有助于改善量子计量学，量子远程同步，以及在电信波长处更强的局部现实主义违反的基本测试。
