Outline

Single photon sources at telecommunication wavelength is promising for the quantum cryptography with unconditional security. However, the single photon sources with the conventional semiconductor quantum dots face challenges in the operation at room temperature. In this study, we propose the nanocarbon-based quantum optoelectronic devices such as single photon sources, electrically-driven emitters, which work at room temperature and telecommunication wavelength. These devices can be applied for high-speed, small-footprint and low-cost quantum cryptography.
