A monolithic silicon Josephson junction can be fabricated from a silicon wafer using semiconductor technologies such as gas immersion laser doping and smart cut technology. Rather than using a superconducting metal for the junction electrodes, silicon that has been highly doped with boron can serve as the superconducting material for the electrodes of the Josephson junction. A region of the silicon wafer that has not been doped serves as the tunnel barrier. Fabrication of the Josephson junction does not require a metallization process since the electrodes and tunnel barrier are formed from highly doped silicon and non-doped silicon, respectively. The single-crystal structure of the resulting Josephson junction yields low two-level system (TLS) noise.
