Measurement of geometric dephasing using a superconducting qubit
S. Berger, M. Pechal, P. Kurpiers +7
A quantum system interacting with its environment is subject to dephasing which ultimately destroys the information it holds. Using a superconducting qubit, we experimentally show…
Exploring Interacting Quantum Many-Body Systems by Experimentally Creating Continuous Matrix Product States in Superconducting Circuits
C. Eichler, J. Mlynek, J. Butscher +4
Improving the understanding of strongly correlated quantum many body systems such as gases of interacting atoms or electrons is one of the most important challenges in modern conde…
Observation of Dicke Superradiance for Two Artificial Atoms in a Cavity with High Decay Rate
J. A. Mlynek, A. A. Abdumalikov, C. Eichler +1
An individual excited two level system decays to its ground state by emitting a single photon in a process known as spontaneous emission. In accordance with quantum theory the prob…
Quantum limited amplification and entanglement in coupled nonlinear resonators
C. Eichler, Y. Salathe, J. Mlynek +2
We demonstrate a coupled cavity realization of a Bose Hubbard dimer to achieve quantum limited amplification and to generate frequency entangled microwave fields with squeezing par…
Collective Suppression of Linewidths in Circuit QED
Felix Nissen, Johannes M. Fink, Jonas A. Mlynek +2
We report the experimental observation, and a theoretical explanation, of collective suppression of linewidths for multiple superconducting qubits coupled to a good cavity. This de…
Demonstrating W-type Entanglement of Dicke-States in Resonant Cavity Quantum Electrodynamics
Jonas A. Mlynek, Abdufarrukh A. Abdumalikov, Johannes M. Fink +5
Nonlinearity and entanglement are two important properties by which physical systems can be identified as non-classical. We study the dynamics of the resonant interaction of up to…
