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…
Parity-Engineered Light-Matter Interaction
Jan Goetz, Frank Deppe, Kirill G. Fedorov +6
The concept of parity describes the inversion symmetry of a system and is of fundamental relevance in the standard model, quantum information processing, and field theory. In quant…
Finite-time quantum entanglement in propagating squeezed microwaves
Kirill G. Fedorov, S. Pogorzalek, U. Las Heras +13
Two-mode squeezing is a fascinating example of quantum entanglement manifested in cross-correlations of incompatible observables between two subsystems. At the same time, these sub…
Photon Statistics of Propagating Thermal Microwaves
J. Goetz, S. Pogorzalek, F. Deppe +7
In experiments with superconducting quantum circuits, characterizing the photon statistics of propagating microwave fields is a fundamental task. We quantify the ph…
Second-order decoherence mechanisms of a transmon qubit probed with thermal microwave states
J. Goetz, F. Deppe, P. Eder +9
Thermal microwave states are omnipresent noise sources in superconducting quantum circuits covering all relevant frequency regimes. We use them as a probe to identify three second-…
Displacement of propagating squeezed microwave states
Kirill G. Fedorov, L. Zhong, S. Pogorzalek +16
Displacement of propagating quantum states of light is a fundamental operation for quantum communication. It enables fundamental studies on macroscopic quantum coherence and plays…
