Low-Loss Superconducting Resonators Fabricated from Tantalum Films Grown at Room Temperature
Guillaume Marcaud, David Perello, Cliff Chen +16
The use of -tantalum in superconducting circuits has enabled a considerable improvement of the coherence time of transmon qubits. The standard approach to grow -tantalum th…
