Abstract: Dissipative Kerr soliton (DKS) frequency comb exhibits broad and narrow-linewidth frequency modes, which make it suitable for quantum communication. However, scalable quantum network based on multiple independent combs is still a challenge due to their fabrication-induced frequency mismatches. This limitation becomes critical in measurement-device-independent quantum key distribution, which requires high visibility of Hong-Ou-Mandel interference between multiple frequency channels. Here, we experimentally demonstrate two independent DKS combs with ten spectrally aligned lines without any frequency locking system. The visibility for individual comb-line pairs reaches up to $46.72 \pm 0.63\%$ via precision frequency translation, establishing a foundation for deploying DKS combs in multi-user quantum networks.

Threshold-less and Flexibly Tunable Frequency Comb via Floquet Engineering [7.430535130527771]
A new type of frequency comb-Floquet cavity frequency comb does not rely on intrinsic non-linearity. We implement this on a microwave cavity optomechanical system on-chip. Compared to Kerr optomechanical combs, this approach efficiently generates comb with pump signal far from the cavity's intrinsic frequency.
