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…
Josephson junctions based on ultraclean carbon nanotubes
S. Annabi, E. Arrighi, A. Peugeot +6
We present a technique for integrating ultraclean carbon nanotubes into superconducting circuits, aiming to realize Josephson junctions based on one-dimensional elementary quantum…
Two-tone spectroscopy of high-frequency quantum circuits with a Josephson emitter
A. Peugeot, H. Riechert, S. Annabi +7
We perform two-tone spectroscopy on quantum circuits, where high-frequency radiation is generated by a voltage-biased superconductor-normal-superconductor Josephson junction and de…
