## Description

- description: Quantum light sources using single-walled carbon nanotubes show promise
    for quantum technologies but face challenges in achieving precise control over
    color center formation. Here we present a novel technique for deterministic creation
    of single organic color centers in carbon nanotubes using \textit{in-situ} photochemical
    reaction. By monitoring discrete intensity changes in photoluminescence spectra,
    we achieve precise control over the formation of individual color centers. Furthermore,
    our method allows for position-controlled formation of color centers as validated
    through photoluminescence imaging. We also demonstrate photon antibunching from
    a color center, confirming the quantum nature of the defects formed. This technique
    represents a significant step forward in the precise engineering of atomically
    defined quantum emitters in carbon nanotubes, facilitating their integration into
    advanced quantum photonic devices and systems.
