Native-oxide-passivated trilayer junctions for superconducting qubits
Pankaj Sethi, Om Prakash, Jukka-Pekka Kaikkonen +15
Superconducting qubits in today's quantum processing units are typically fabricated with angle-evaporated aluminum--aluminum-oxide--aluminum Josephson junctions. However, there is…
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…
Wafer-scale CMOS-compatible graphene Josephson field-effect transistors
Andrey A. Generalov, Klaara L. Viisanen, Jorden Senior +5
Electrostatically tunable Josephson field-effect transistors (JoFETs) are one of the most desired building blocks of quantum electronics. JoFET applications range from parametric a…
Terahertz detection with graphene FETs: photothermoelectric and resistive self-mixing contributions to the detector response
Florian Ludwig, Andrey Generalov, Jakob Holstein +4
Field-effect transistors coupled to integrated antennas (TeraFETs) are photodetectors being actively developed for the THz frequency range ( 100 GHz - 10 THz). Among them, Gr…
