Absence of Charge Offset Drift in a Transmon Qubit
Adria Rospars, Hector Hutin, Yannick Seis +8
Superconducting quantum circuits are sensitive to their electrostatic environment: uncontrolled charges accumulating on the electrodes of a Josephson junction shift the energy leve…

Towards a Josephson element using aluminum junctions with well-transmitted channels
J. Griesmar, H. Riechert, M. Hantute +8
We introduce a novel method for fabricating all-aluminum Josephson junctions with highly transmitted conduction channels. Such properties are typically associated with structures r…

The carbon nanotube gatemon qubit
H. Riechert, S. Annabi, A. Peugeot +8
Gate-tunable transmon qubits are based on quantum conductors used as weak links within hybrid Josephson junctions. These gatemons have been implemented in just a handful of systems…
