Epitaxial rhenium microwave resonators
E Dumur, B Delsol, T Weißl +8
We have fabricated rhenium microwave resonators from epitaxial films. We have used thin films of different structural quality depending on their growth conditions. The resonators w…
Unexpectedly allowed transition in two inductively coupled transmons
Étienne Dumur, Bruno Küng, Alexey Feofanov +6
We present experimental results in which the unexpected zero-two transition of a circuit composed of two inductively coupled transmons is observed. This transition shows an unusual…
Kerr coefficients of plasma resonances in Josephson junction chains
Thomas Weißl, Bruno Küng, Étienne Dumur +6
We present an experimental and theoretical analysis of the self- and cross-Kerr effect of extended plasma resonances in Josephson junction chains. We calculate the Kerr coefficient…
A V-shape superconducting artificial atom based on two inductively coupled transmons
É. Dumur, B. Küng, A. K. Feofanov +5
Circuit quantum electrodynamics systems are typically built from resonators and two-level artificial atoms, but the use of multi-level artificial atoms instead can enable promising…
A Superconducting 180° Hybrid Ring Coupler for circuit Quantum Electrodynamics
E. Hoffmann, F. Deppe, T. Niemczyk +11
Superconducting circuit quantum electrodynamics experiments with propagating microwaves require devices acting as beam splitters. Using niobium thin films on silicon and sapphire s…
Two-resonator circuit QED: Dissipative Theory
Georg M. Reuther, David Zueco, Frank Deppe +9
We present a theoretical treatment for the dissipative two-resonator circuit quantum electrodynamics setup referred to as quantum switch. There, switchable coupling between two sup…
