Josephson Junction Arrays: Parasitic Capacitances
Explains why capacitance to ground limits the number of junctions in a fluxonium array, then compares simulated junction capacitances with parallel-plate theory and measured data. It studies how Dolan-bridge geometry affects parasitic capacitance, discusses a bridge-free fabrication alternative, and sketches ongoing work on array Q and faster numerical diagonalization of fluxonium.
- Role of series junction arrays in fluxonium and the limit set by capacitance to ground
- Simulated vs. empirical junction capacitance per area
- Dolan-bridge geometry study and design guidelines for minimizing parasitic capacitance
- Bridge-free junction technique, array loss, and algebraic diagonalization of fluxonium
Summary and key points drafted by a language model from the slides, not yet reviewed by me. The slides are the source.
