Measurement of a Vacuum-Induced Geometric Phase
Simone Gasparinetti, Simon Berger, Abdufarrukh A. Abdumalikov +3
Berry's geometric phase naturally appears when a quantum system is driven by an external field whose parameters are slowly and cyclically changed. A variation in the coupling betwe…
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…
Microwave-Induced Amplitude and Phase Tunable Qubit-Resonator Coupling in Circuit Quantum Electrodynamics
S. Zeytinoglu, M. Pechal, S. Berger +3
In the circuit quantum electrodynamics architecture, both the resonance frequency and the coupling of superconducting qubits to microwave field modes can be controlled via external…
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…
Microwave-controlled generation of shaped single photons in circuit quantum electrodynamics
M. Pechal, L. Huthmacher, C. Eichler +5
Large-scale quantum information processors or quantum communication networks will require reliable exchange of information between spatially separated nodes. The links connecting t…
Experimental Realization of Non-Abelian Geometric Gates
A. A. Abdumalikov, J. M. Fink, K. Juliusson +4
The geometric aspects of quantum mechanics are underlined most prominently by the concept of geometric phases, which are acquired whenever a quantum system evolves along a closed p…
