Demonstration of dual Shapiro steps in small Josephson junctions
Fabian Kaap, Christoph Kissling, Victor Gaydamachenko +2
Bloch oscillations in small Josephson junctions were predicted theoretically as the quantum dual to Josephson oscillations. A significant consequence of this prediction is the emer…
Mitigation of quasiparticle loss in superconducting qubits by phonon scattering
Arno Bargerbos, Lukas Johannes Splitthoff, Marta Pita-Vidal +6
Quantum error correction will be an essential ingredient in realizing fault-tolerant quantum computing. However, most correction schemes rely on the assumption that errors are suff…
Singlet-doublet transitions of a quantum dot Josephson junction detected in a transmon circuit
Arno Bargerbos, Marta Pita-Vidal, Rok Žitko +10
We realize a hybrid superconductor-semiconductor transmon device in which the Josephson effect is controlled by a gate-defined quantum dot in an InAs/Al nanowire. Microwave spectro…
Gate-tunable kinetic inductance in proximitized nanowires
Lukas Johannes Splitthoff, Arno Bargerbos, Lukas Grünhaupt +6
We report the detection of a gate-tunable kinetic inductance in a hybrid InAs/Al nanowire. For this purpose, we have embedded the nanowire into a quarter-wave coplanar waveguide re…
Subgap kinetic inductance detector sensitive to 85-GHz radiation
F. Levy-Bertrand, A. Benoît, O. Bourrion +8
We have fabricated an array of subgap kinetic inductance detectors (SKIDs) made of granular aluminum (2~K) sensitive in the 80-90 GHz frequency band and operating at 300~m…
Quantum non-demolition dispersive readout of a superconducting artificial atom using large photon numbers
Daria Gusenkova, Martin Spiecker, Richard Gebauer +13
Reading out the state of superconducting artificial atoms typically relies on dispersive coupling to a readout resonator. For a given system noise temperature, increasing the circu…
