Digital quantum simulation of spin models with circuit quantum electrodynamics
Y. Salathé, M. Mondal, M. Oppliger +9
Systems of interacting quantum spins show a rich spectrum of quantum phases and display interesting many-body dynamics. Computing characteristics of even small systems on conventio…
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…
Photon-mediated interactions between distant artificial atoms
Arjan F. van Loo, Arkady Fedorov, Kevin Lalumière +3
Photon-mediated interactions between atoms are of fundamental importance in quantum optics, quantum simulations and quantum information processing. The exchange of real and virtual…
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…
Characterizing Quantum Microwave Radiation and its Entanglement with Superconducting Qubits using Linear Detectors
C. Eichler, D. Bozyigit, A. Wallraff
Recent progress in the development of superconducting circuits has enabled the realization of interesting sources of nonclassical radiation at microwave frequencies. Here, we discu…
Geometric phases in superconducting qubits beyond the two-level-approximation
S. Berger, M. Pechal, S. Pugnetti +5
Geometric phases, which accompany the evolution of a quantum system and depend only on its trajectory in state space, are commonly studied in two-level systems. Here, however, we s…
