Broadband and high-precision two-level system loss measurement using superconducting multi-wave resonators
Cliff Chen, Shahriar Aghaeimeibodi, Yuki Sato +3
Two-level systems (TLS) are known to be a dominant source of dissipation and decoherence in superconducting qubits. Superconducting resonators provide a convenient way to study TLS…

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 thin…
