Superconductor-insulator transition in nanowires and nanowire arrays

Hans Mooij, Gerd Schön, Alexander Shnirman +4

Superconducting nanowires are the dual elements to Josephson junctions, with quantum phase-slip processes replacing the tunneling of Cooper pairs. When the quantum phase-slip ampli…

Multi-photon dressing of an anharmonic superconducting many-level quantum circuit

Jochen Braumüller, Joel Cramer, Steffen Schlör +10

We report on the investigation of a superconducting anharmonic multi-level circuit that is coupled to a harmonic readout resonator. We observe multi-photon transitions via virtual…

Aluminium-oxide wires for superconducting high kinetic inductance circuits

H. Rotzinger, S. T. Skacel, M. Pfirrmann +7

We investigate thin films of conducting aluminium-oxide, also known as granular aluminium, as a material for superconducting high quality, high kinetic inductance circuits. The fil…

Probing the TLS Density of States in SiO Films using Superconducting Lumped Element Resonators

S. T. Skacel, Ch. Kaiser, S. Wuensch +6

We have investigated dielectric losses in amorphous SiO thin films under operating conditions of superconducting qubits (mK temperatures and low microwave powers). For this purpose…

One-dimensional Josephson junction arrays: Lifting the Coulomb blockade by depinning

Nicolas Vogt, Roland Schäfer, Hannes Rotzinger +4

Experiments with one-dimensional arrays of Josephson junctions in the regime of dominating charging energy show that the Coulomb blockade is lifted at the threshold voltage, which…
