International audienceThe single-wall carbon nanotubes are currently studied and developed because of their unique physical properties. In particular, single-photon emission at room temperature has been recently reported. This has been achieved by surface chemistry that creates point-like defects that localize the nanotube's exciton. The design of these defects allows to create potential well with deepness far above kT leading to the antibunching at room T. The last achievement reports g$^2$(0)<0.01 at room T and in the telecom wavelength bands. Concomitantly, first Cavity Quantum Electrodynamics experiments have been carried out using nanotubes as the quantum emitter. In particular, Purcell effect and cavity feeding has been recently repor...
