Quantum emitters in two dimensions

Integrated circuits that process information encoded in individual quantized states of the electromagnetic field are poised to revolutionize information processing, communications, and sensing technologies. An emerging class of such quantum technologies is based on solid-state, on-demand single-photon emitters (SPEs) coupled to optical resonators and waveguides that serve as building blocks for high-density, on-chip quantum circuits ( 1 ). To date, the most investigated solid-state SPE systems are epitaxial quantum dots (QDs) that operate primarily at cryogenic temperatures, and color centers in solids. A noteworthy example of the latter is the nitrogen vacancy defect (NV-center) in diamond, which has become a standard for the myriad quantum optics experiments and inspired numerous studies of SPEs ( 2 ).

    Random number generators go public

    On 10 July, researchers in Chile will unveil an online public random number service. Later in July, the U.S. National Institute of Standards and Technology (NIST) will launch its Randomness Beacon as a permanent service, upgrading a pilot program that began in 2013. Brazil, too, is planning ... more

    When the cure kills—CBD limits biodiversity research

    The Convention on Biological Diversity (CBD) commits its 196 nation parties to conserve biological diversity, use its components sustainably, and share fairly and equitably the benefits from the utilization of genetic resources. The last of these objectives was further codified in the Conve ... more

    See-through solar cells could power offices

    Solar windows turn some of the light shining through into electricity. They've been on the market for years. But many of these windows absorb some visible light, leaving them with a reddish or brownish hue, a trait frowned on by architects. Now, new versions are on the way that absorb invis ... more

    It's Not an Illusion

    Researchers have developed a compound that can transform near-infrared light into broadband white-light, offering a cheap, efficient means to produce visible light. The emitted light is also exceedingly directional, a desirable quality for devices like microscopes that require high spatial ... more
