Wiring surface loss of a superconducting transmon qubit
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 3 piece horse wall art Josephson junction (or SQUID) by a superconducting thin metal wiring.Here, we report on finite-element simulation and experimental
