Two-photon probe of the Jaynes-Cummings model and symmetry breaking in circuit QED
Frank Deppe, Matteo Mariantoni, E. P. Menzel +9
Superconducting qubits behave as artificial two-level atoms and are used to investigate fundamental quantum phenomena. In this context, the study of multi-photon excitations occupi…
Phase-Coherent Dynamics of a Superconducting Flux Qubit with Capacitive-Bias Readout
F. Deppe, M. Mariantoni, E. P. Menzel +7
We present a systematic study of the phase-coherent dynamics of a superconducting three-Josephson-junction flux qubit. The qubit state is detected with the integrated-pulse method,…
Dephasing of a superconducting flux qubit
K. Kakuyanagi, T. Meno, S. Saito +5
In order to gain a better understanding of the origin of decoherence in superconducting flux qubits, we have measured the magnetic field dependence of the characteristic energy rel…
Vacuum Rabi oscillations in a macroscopic superconducting qubit LC oscillator system
J. Johansson, S. Saito, T. Meno +4
We have observed the coherent exchange of a single energy quantum between a flux qubit and a superconducting LC circuit acting as a quantum harmonic oscillator. The exchange of an…
Parametric control of a superconducting flux qubit
S. Saito, T. Meno, M. Ueda +3
Parametric control of a superconducting flux qubit has been achieved by using two-frequency microwave pulses. We have observed Rabi oscillations stemming from parametric transition…
Multiphoton transitions in a macroscopic quantum two-state system
S. Saito, M. Thorwart, H. Tanaka +4
We have observed multiphoton transitions between two macroscopic quantum-mechanical superposition states formed by two opposite circulating currents in a superconducting loop with…
