Asymmetric photon bunching recurring interferences and distributions via quantum frequency combs
Published on 2026-06-04 by Kai-Chi Chang, Xiang Cheng, Yujie Chen and Chee Wei Wong @IOP SCIENCE
Abstract: Quantum frequency combs (QFCs) exhibit periodic temporal recurrences arising from the Fourier transform of their mode-locked frequency spectra. While QFCs have been experimentally demonstrated, asymmetric Hong–Ou–Mandel (HOM) revival interference in QFCs has not been systematically investigated, and the efficient distribution of photon-bunching revivals has remained unreported. Here, we present the first experimental observation and distribution of asymmetric HOM recurrence interference usin[...]
Our summary: This study presents the first experimental observation of asymmetric Hong–Ou–Mandel revival interference using quantum frequency combs. The research demonstrates high visibility in HOM revivals across multiple time-bins from QFCs. Results indicate that QFCs are suitable for advanced quantum information processing applications.
