Quantifying Trapped Magnetic Vortex Losses in Niobium Resonators at mK Temperatures
Trapped magnetic vortices in niobium can introduce microwave losses in superconducting devices, affecting both niobium-based qubits and resonators. While our group has extensively studied
2D transmons with lifetimes and coherence times exceeding 1 millisecond
Materials improvements are a powerful approach to reducing loss and decoherence in superconducting qubits because such improvements can be readily translated to large scale processors.
