In-situ tunable nonlinearity and competing signal paths in coupled superconducting resonators
Michael Fischer, Qi-Ming Chen, Christian Besson +10
We have fabricated and studied a system of two tunable and coupled nonlinear superconducting resonators. The nonlinearity is introduced by galvanically coupled dc-SQUIDs. We simula…
Quantum probe of an on-chip broadband interferometer for quantum microwave photonics
P. Eder, T. Ramos, J. Goetz +11
Quantum microwave photonics aims at generating, routing, and manipulating propagating quantum microwave fields in the spirit of optical photonics. To this end, the strong nonlinear…
Compact 3D quantum memory
Edwar Xie, Frank Deppe, Michael Renger +8
Superconducting 3D microwave cavities offer state-of-the-art coherence times and a well controlled environment for superconducting qubits. In order to realize at the same time fast…
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…
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…
