Abstract Quantum processors using superconducting qubits suffer from dielectric loss leading to noise and dissipation. Qubits are usually designed as large capacitor pads connected to a non-linear Josephson junction (or SQUID) by a superconducting thin metal wiring. Here. we report on finite-element simulation and experimental results confirming that more than 50% of surface loss in t... https://allfixelectricales.shop/product-category/spray-arm-guide-kit/
