The researchers of Los Alamos are discovering the enhanced potentials of the carbon nanotubes for processing the quantum information. Here while processing the quantum information, the carbon nanotubes function as single-photon emitters. Their research analysis finds a place in the journal Nature Materials.

Stephen Doorn says, “We are particularly interested in advances in nanotube integration into photonic cavities for manipulating and optimizing light-emission properties.” Stephen Doorn is the researcher at Los Alamos National Laboratory. He further adds, “In addition, nanotubes integrated into electroluminescent devices can provide greater control over the timing of light emission, and they can be feasibly integrated into photonic structures. We are highlighting the development and photophysical probing of carbon nanotube defect states as routes to room-temperature single photon emitters at telecom wavelengths.”

The team’s overview is generated in collaboration with their colleagues in Paris. These colleagues in Paris (Christophe Voisin) are involved in integrating the nanotubes with the photonic cavities. This integration modifies their rate of emission. At Karlsruhe, these researchers are engaged in the inclusion of electroluminescent devices. These electro-luminescent devices are based on nanotube and are influenced by structures of the photonic waveguides.

Los Alamos researchers focus more on analysis and subsequent identification of defects in the nanotubes. This analysis and identification direct quantum emission towards the room temperature as well as the wavelengths of telecom.

The scientific paper on the current study further notes, “With the advent of high-speed information networks, light has become the main worldwide information carrier. Single-photon sources are a key building block for a variety of technologies, in secure quantum communications metrology or quantum computing schemes.”
