Low-loss Millimeter-wave Resonators with an Improved Coupling Structure
Alexander Anferov, Shannon P. Harvey, Fanghui Wan +3
Millimeter-wave superconducting resonators are a useful tool for studying quantum device coherence in a new frequency domain. However, improving resonators is difficult without a r…
