"defects in silicon, quantum emitters, trap single electrons, send/ store quantum information over widely used wavelengths... simple electric diode manipulates qubits inside commercial silicon wafer, changing electric field, tune its wavelength, turn it on/ off... electrons hit with laser emit photons in specific wavelengths... G-center defects made adding hydrogen atoms to lattice... fabricate hundreds of devices with embedded defect in each device, across a commercial wafer. negative voltage turned off defects"
