Title: Fine-grained All-fiber Nonlocal Dispersion Compensation in the Telecommunications O-Band
Authors: RuiMing Chua, James A. Grieve, Alexander Ling
Abstract summary: Photon timing correlations were preserved down to 51ps$pm$21ps over two multi-segmented 10km spans of deployed metropolitan fiber. This degree of compensation can be achieved with relatively large fiber (1km), compatible with real-world deployment.

Abstract: Nonlocal dispersion compensation between broadband photon pairs propagated over fiber corresponding to the ITU-T G.652D telecommunications standard was studied via fine-grained measurements of the temporal correlation between them. We demonstrated near-ideal levels of nonlocal dispersion compensation by adjusting the propagation distance of the photon pairs to preserve photon timing correlations close to the effective instrument resolution of our detection apparatus (41.0$\pm$0.1ps). Experimental data indicates that this degree of compensation can be achieved with relatively large fiber increments (1km), compatible with real-world deployment. Ultimately, photon timing correlations were preserved down to 51ps$\pm$21ps over two multi-segmented 10km spans of deployed metropolitan fiber.

Ultrabright fiber-coupled ploarization-entangled photon source with spectral brightness surpassing 2.0 MHz/mW/nm [0.6581049960856515]
We present an ultrabright polarization-entangled photon source that is optimally coupled into single-mode fibers. By employing a simple mode-matching optical setup, we optimize the SMF coupling and heralding efficiencies of the photon-pairs. This represents the highest spectral brightness of SPDC photons generated using a CW laser pumped bulk crystal to date.

Implementation of quantum synchronization over a 20-km fiber distance based on frequency-correlated photon pairs and HOM interference [3.9137835408510298]
The quantum synchronization based on frequency-correlated photon pairs and HOM interference has shown femtosecond-level precision. Due to the difficulty of achieving stable HOM interference fringe after long-distance fiber transmission, this quantum synchronization is hampered from long-haul field application. We successfully achieved the stable observation of the two-photon interference of the lab-developed broadband frequency-correlated photon pairs after 20 km-long fiber transmission.

We demonstrate a quantum key distribution implementation over deployed dark telecom fibers with polarisation-entangled photons generated at the O-band. One of the photons in the pairs are propagated through 10km of deployed fiber while the others are detected locally. This ensures continuous and stable QKD operation with an average QBER of 6.4% and a final key rate of 109 bits/s.
