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…

Effect of ion irradiation on superconducting thin films
Katja Kohopää, Alberto Ronzani, Robab Najafi Jabdaraghi +8
We demonstrate ion irradiation by argon or gallium as a wafer-scale post-processing method to increase disorder in superconducting thin films. We study several widely used supercon…
