Towards an electrically driven single photon source made from a carbon nanotube

On-demand single photon sources have potential applications in quantum cryptography, quantum computing, and metrology. In particular, there is a need for devices that can be integrated into an on-chip network and can produce indistinguishable photons on-demand. Such devices would enable practical designs for all-optical quantum computers. We aim to create electrically driven single photon sources using individual semiconducting carbon nanotubes with sp³ defects. Novel aspects of our device design include integration with van der Waals heterostructures, and the use of electrostatic gating to form p-n junctions. I will show why this is a promising platform, and discuss our progress towards fabricating a working prototype.
