"2D monolayer tungsten diselenide semiconductors have excellent electronics/ optics... heated introducing small number of defects, artificially break crystal symmetry resulting in bright/ dark excitons luminescence peaks... applied magnetic field (even relatively weak) significantly increased emission intensity... photon antibunching shows photons emitted 1 by 1... secure, efficient, and compact quantum information devices"
