A nano-scale “corral” for light-emitting particles (IMAGE)

Future quantum technologies require efficient ways to connect matter-based quantum states with light. One promising approach uses excitons—quasiparticles formed when light creates bound electron-hole pairs inside a semiconductor. Excitons interact strongly with light, making them attractive for quantum communication and photonic technologies. Boston College researchers report in Nature Nanotechnology they created an electrically tunable quantum nano-scale corral that traps charged excitons and enables precise electrical control of tiny light sources, including their brightness, color, and quantum states.
