Room-Temperature Giant Stark Effect of Single Photon Emitter in van der Waals Material

Single photon emitters (SPEs) are critical building blocks needed for quantum science and technology. For practical applications, room-temperature solid-state platforms are critically demanded. To scale up quantum information processing using, for example, wavelength division multiplexing quantum key distribution, a large tuning range beyond emission line width of single photon energy is required. Stark effect can tune the single photon energy...
