    Tweezers Enable Dynamic Control of Single Nanoscale Quantum Objects

    Article obtained from Photonics RSS Feed.

    Led by Justus Ndukaife, assistant professor of electrical engineering, Vanderbilt researchers have introduced an approach for trapping and moving a single colloidal nanodiamond with nitrogen-vacancy center using a low-power laser beam. The width of a single human hair is approximately 90,000 nm; nanodiamonds are less than 100 nm. These carbon-based materials are one of the few that can release a single photon, considered a building block for future quantum photonics applications, Ndukaife said.

    It is currently possible to trap nanodiamonds using light fields focused near nano-size metallic surfaces, but it is not possible to move them that way; laser beam spots are simply too big. Using an atomic force microscope, it takes scientists…
