Revisiting Thermal Scalability for Large-Scale Superconducting Quantum Systems
Shaswot Shresthamali, Ilkwon Byun, Teruo Tanimoto +4
The readout amplification chain imposes a critical thermal scalability bottleneck in large-scale superconducting quantum systems. This happens through three mechanisms: amplifier d…

Microwave characterization of tantalum superconducting resonators on silicon substrate with niobium buffer layer
Yoshiro Urade, Kay Yakushiji, Manabu Tsujimoto +4
Tantalum thin films sputtered on unheated silicon substrates are characterized with microwaves at around 10 GHz in a 10 mK environment. We show that the phase of tantalum with a bo…
