Quantum Light (IMAGE) DOE/Los Alamos National Laboratory Caption Los Alamos National Laboratory researchers have produced the first known material capable of single-photon emission at room temperature and at telecommunications wavelengths, using chemically functionalized carbon nanotubes. These quantum light emitters are important for optically based quantum information processing and information security, ultrasensitive sensing, metrology and imaging needs and as photon sources for quantum optics studies.
