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…
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…
Beyond the Jaynes-Cummings model: circuit QED in the ultrastrong coupling regime
T. Niemczyk, F. Deppe, H. Huebl +9
In cavity quantum electrodynamics (QED), light-matter interaction is probed at its most fundamental level, where individual atoms are coupled to single photons stored in three-dime…
Dual-path state reconstruction scheme for propagating quantum microwaves and detector noise tomography
E. P. Menzel, F. Deppe, M. Mariantoni +7
Quantum state reconstruction involves measurement devices that are usually described by idealized models, but not known in full detail in experiments. For weak propagating microwav…
