Scaling-up optical quantum technologies requires a combination of highly efficient multi-photon sources and integrated waveguide components. Here, we interface these scalable platforms, demonstrating high-rate three-photon interference with a quantum dot based multi-photon source and a reconfigurable photonic chip on glass. We actively demultiplex the temporal train of single photons obtained from a quantum emitter to generate a $3.8\times {10}^3{\mathrm{s}}^{-1}$three-photon source, which is then sent to the input of a tunable tritter circuit, demonstrating the on-chip quantum interference of three indistinguishable single photons. We show via pseudo number-resolving photon detection characterizing the output distribution that this first combination of scalable sources and reconfigurable photonic circuits compares favorably in performance with respect to previous implementations. Our detailed loss-budget shows that merging solid-state multi-photon sources and reconfigurable photonic chips could allow 10-photon experiments on chip at $\sim 40{\mathrm{s}}^{-1}$ rate in a foreseeable future.

连接可扩展光子平台：可重构玻璃芯片中基于固态的多光子干涉

放大光学量子技术需要高效的多光子源和集成的波导组件的组合。在这里，我们将这些可扩展平台连接起来，展示了基于量子点的多光子源和玻璃上可重构光子芯片的高速率三光子干扰。我们积极地对从量子发射器获得的单个光子的时间序列进行解复用，以生成一个$3.8\times {10}^3{\mathrm{s}}^{-\mathrm{1个}}$三光子源，然后将其发送到可调三振器电路的输入，演示了三个不可区分的单光子的片上量子干扰。通过对输出分布进行特征化的伪数解析光子检测，我们可以看出，这种可扩展光源和可重配置光子电路的第一种组合在性能上相对于以前的实现方式具有可比性。我们的详细损失预算显示，将固态多光子源与可重构光子芯片合并可以在芯片上进行10光子实验，$〜40{\mathrm{s}}^{-\mathrm{1个}}$ 在可预见的将来率。
