Progress in quantum computing and quantum cryptography requires efficient, electrically triggered, single-photon sources at room temperature in the telecom wavelengths. It has been long known that semiconducting single-wall carbon nanotubes (SWCNTs) display strong excitonic binding and emit light over a broad range of wavelengths, but their use has been hampered by a low quantum yield and a high sensitivity to spectral diffusion and blinking. In this Perspective, we discuss recent advances in the mastering of SWCNT optical properties by chemistry, electrical contacting and resonator coupling towards advancing their use as quantum light sources. We describe the latest results in terms of single-photon purity, generation efficiency and indistinguishability. Finally, we consider the main fundamental challenges stemming from the unique properties of SWCNTs and the most promising roads for SWCNT-based chip integrated quantum photonic sources.

量子计算和量子密码技术的进步要求在室温下在电信波长下提供高效的电触发单光子源。众所周知，半导电单壁碳纳米管（SWCNT）具有很强的激子结合能力，并能在很宽的波长范围内发光，但是由于量子产率低，对光谱扩散和闪烁的敏感性高，阻碍了它们的使用。在此观点中，我们讨论了通过化学，电接触和共振器耦合掌握SWCNT光学特性的最新进展，以促进将其用作量子光源。我们根据单光子纯度，产生效率和不可分辨性来描述最新结果。最后，
