Carbon Nanotube Optics Poised to Provide Pathway to Optical-Based Quantum Cryptography and Quantum C (image) DOE/Los Alamos National Laboratory Share Print E-Mail Caption Depiction of a carbon nanotube defect site generated by functionalization of a nanotube with a simple organic molecule. Altering the electronic structure at the defect enables room-temperature single photon emission at telecom wavelengths.
