Loss mechanisms in superconducting thin film microwave resonators
Jan Goetz, Frank Deppe, Max Haeberlein +10
We present a systematic analysis of the internal losses of superconducting coplanar waveguide microwave resonators based on niobium thin films on silicon substrates. In particular,…
Tunable coupling of transmission-line microwave resonators mediated by an rf SQUID
F. Wulschner, J. Goetz, F. R. Koessel +18
We realize tunable coupling between two superconducting transmission line resonators. The coupling is mediated by a non-hysteretic rf SQUID acting as a flux-tunable mutual inductan…
Spin-boson model with an engineered reservoir in circuit quantum electrodynamics
Max Haeberlein, Frank Deppe, Andreas Kurcz +14
A superconducting qubit coupled to an open transmission line represents an implementation of the spin-boson model with a broadband environment. We show that this environment can be…
Ultrastrong coupling in two-resonator circuit QED
A. Baust, E. Hoffmann, M. Haeberlein +17
We report on ultrastrong coupling between a superconducting flux qubit and a resonant mode of a system comprised of two superconducting coplanar stripline resonators coupled galvan…
Dual-Path Methods for Propagating Quantum Microwaves
R. Di Candia, E. P. Menzel, L. Zhong +4
We study quantum state tomography, entanglement detection, and channel noise reconstruction of propagating quantum microwaves via dual-path methods. The presented schemes make use…
Path Entanglement of Continuous-Variable Quantum Microwaves
E. P. Menzel, R. Di Candia, F. Deppe +13
Path entanglement constitutes an essential resource in quantum information and communication protocols. Here, we demonstrate frequency-degenerate entanglement between continuous-va…
