Plug‐and‐Play Single‐Photon Devices with Efficient Fiber‐Quantum Dot Interface Abstract Incorporating solid‐state quantum emitters into optical fiber networks enables the long‐distance transmission of quantum information and the remote connection of distributed quantum nodes. However, interfacing quantum emitters with fiber optics encounters several challenges, including low coupling efficiency and delicate configuration. In this study, a highly efficient fiber‐interfacing photonic device that ...
