Josephson traveling-wave parametric amplifier based on low-intrinsic-loss coplanar lumped-element waveguide
C. W. Sandbo Chang, Arjan F. Van Loo, Chih-Chiao Hung +4
We present a Josephson traveling-wave parametric amplifier (JTWPA) based on a low-loss coplanar lumped-element waveguide architecture. By employing open-stub capacitors and Manhatt…
