Electronic primary thermometry -- experimental comparison of the Coulomb Blockade and Shot Noise Thermometer
Eemil Praks, Libin Wang, Yu-Cheng Chang +4
Since the redefinition of the kelvin in 2019, new methods of primary thermometry have been considered to replace the currently agreed temperature scale in the very high and low tem…
A scalable non-superconducting tunnel junction technology
Juho Luomahaara, Kristupas Razas, Omid Sharifi Sedeh +15
Tunnel junctions are one of the key elements of chip-scale microsystems serving various technologies from classical microelectronics to quantum information. Aluminium and its oxide…
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…
Fast optical data transfer into a Josephson junction array
K. Kohopää, J. Nissilä, E. Mykkänen +19
We employ externally shunted Nb-AlO-Nb Josephson junctions for demonstrating a circuit that is suitable for an optically driven Josephson Arbitrary Waveform Synthesizer (JAWS).…
