Electronic cooling of a TiW alloy normal-metal island using Nb-based superconducting tunnel junctions
Joel Hätinen, Renan Pires Loreto, Arvind Kumar +2
TiW thin films remain non-superconducting down to millikelvin temperatures and are compatible with large-scale CMOS manufacturing, making them attractive for cryogenic and quantum…

Efficient electronic cooling above 2 K by niobium-based superconducting tunnel junctions
J. Hätinen, A. Ronzani, R. P. Loreto +15
Replacing the bulky cryoliquid-based cooling stages of cryoenabled instruments by chip-scale refrigeration is envisioned to disruptively reduce the system size similar to microproc…

Scalable on-chip multiplexing of silicon single and double quantum dots
Heorhii Bohuslavskyi, Alberto Ronzani, Joel Hätinen +5
Owing to the maturity of complementary metal oxide semiconductor (CMOS) microelectronics, qubits realized with spins in silicon quantum dots (QDs) are considered among the most pro…
