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…
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…
Selection rules in a strongly coupled qubit-resonator system
T. Niemczyk, F. Deppe, E. P. Menzel +11
Superconducting qubits acting as artificial two-level atoms allow for controlled variation of the symmetry properties which govern the selection rules for single and multiphoton ex…
Planck Spectroscopy and the Quantum Noise of Microwave Beam Splitters
M. Mariantoni, E. P. Menzel, F. Deppe +7
We use a correlation function analysis of the field quadratures to characterize both the black body radiation emitted by a 50 Ohm load resistor and the quantum properties of two ty…
