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…
Many-Body Interactions with Tunable-Coupling Transmon Qubits
A. Mezzacapo, L. Lamata, S. Filipp +1
The efficient implementation of many-body interactions in superconducting circuits allows for the realization of multipartite entanglement and topological codes, as well as the eff…
Digital Quantum Simulation of Spin Systems in Superconducting Circuits
U. Las Heras, A. Mezzacapo, L. Lamata +3
We propose the implementation of a digital quantum simulator for prototypical spin models in a circuit quantum electrodynamics architecture. We consider the feasibility of the quan…
Exploring the Effect of Noise on the Berry Phase
S. Berger, M. Pechal, A. A. Abdumalikov +5
We make use of a superconducting qubit to study the effects of noise on adiabatic geometric phases. The state of the system, an effective spin one-half particle, is adiabatically g…
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…
Driving Rydberg-Rydberg transitions from a co-planar microwave waveguide
S. D. Hogan, J. A. Agner, F. Merkt +3
The coherent interaction between ensembles of helium Rydberg atoms and microwave fields in the vicinity of a solid-state co-planar waveguide is reported. Rydberg-Rydberg transition…
