Abstract
The independent claims of this patent signify a concise description of embodiments. Disclosed is technology for direct measurement of the capacitance of a Josephson junction. Roughly, the technique includes detecting the resonance frequency f of the junction under test, determining the DC voltage Vp across the junction under test at resonance frequency, and determining the capacitance of the junction under test in dependence upon the critical current Ic of the junction under test and the DC voltage Vp. This Abstract is not intended to limit the scope of the claims.
