我们报道了从单个量子点发射的电信波长的共振荧光。我们执行高分辨率光谱和观察摩洛三重态在拉比体制-共振荧光的标志。测量的共振-荧光光谱允许我们排除纯减相作为这些量子点的重要退相干机制。结合数值模拟，实验结果提供了量子点环境中电荷噪声的鲁棒性表征。量子点的共振控制为按需产生电信波长的难以区分的单光子以及量子光学实验和直接操纵电信波长量子点中的固态量子比特开辟了新的可能性。AIP出版社出版。
We report on resonance fluorescence from a single quantum dot emitting at telecom wavelengths. We perform high-resolution spectroscopy and observe the Mollow triplet in the Rabi regime-a hallmark of resonance fluorescence. The measured resonance-fluorescence spectra allow us to rule out pure dephasing as a significant decoherence mechanism in these quantum dots. Combined with numerical simulations, the experimental results provide robust characterisation of charge noise in the environment of the quantum dot. Resonant control of the quantum dot opens up new possibilities for the on-demand generation of indistinguishable single photons at telecom wavelengths as well as quantum optics experiments and direct manipulation of solid-state qubits in telecom-wavelength quantum dots.
