Josephson junctions are quantum mechanical devices consisting of two superconductors separated by a thin insulating barrier. They are named after Brian Josephson, who predicted their unique properties ...

while the qubit’s Josephson junction was fabricated using double-angle evaporation of aluminum and electron beam lithography. An arbitrary waveform generator with a 1 GHz sampling rate was ...

Switching takes place in a few picoseconds. Although Josephson junctions have not materialized for ordinary computer circuits, they have been used thus far in medical instruments and quantum ...

This typically involves quantum effects inherent to low temperature superconducting systems made with advanced photo and e-beam lithography to fabricate ultra-small quantum circuits. My research ...

SIS junctions have superconducting electrodes separated by a thin insulating barrier. The superconducting properties of the electrodes lead to unique tunneling characteristics, such as the Josephson ...
