Hot electron heatsinks for microwave attenuators below 100 mK
Jen-Hao Yeh, Rui Zhang, Shavindra Premaratne +3
We demonstrate improvements to the cooling power of broad bandwidth (10 GHz) microwave attenuators designed for operation at temperatures below 100 mK. By interleaving 9-m thick…

Microwave attenuators for use with quantum devices below 100 mK
Jen-Hao Yeh, Jay LeFebvre, Shavindra Premaratne +2
To reduce the level of thermally generated electrical noise transmitted to superconducting quantum devices operating at 20 mK, we have developed thin-film microwave power attenuato…
