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…
Tunable and Switchable Coupling Between Two Superconducting Resonators
A. Baust, E. Hoffmann, M. Haeberlein +16
We realize a device allowing for tunable and switchable coupling between two superconducting resonators mediated by an artificial atom. For the latter, we utilize a persistent curr…
Squeezing with a flux-driven Josephson parametric amplifier
L. Zhong, E. P. Menzel, R. Di Candia +12
Josephson parametric amplifiers (JPA) are promising devices for applications in circuit quantum electrodynamics (QED) and for studies on propagating quantum microwaves because of t…
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…
