Dielectric Loss of Boron-Based Dielectrics on Niobium Resonators [PDF]
Journal of Low Temperature Physics, 2019 Advanced solid-state quantum bits (qubits) are likely to require a variety of dielectrics for wiring crossovers, substrates, and Josephson junctions. Microwave superconducting resonators are an excellent tool for measuring the internal dielectric loss of materials. We report the dielectric loss of boron-based dielectric films using a microwave coplanar
