Readout strength dependence of state projection in superconducting qubit
K. Kakuyanagi, H. Nakano, S. Kagei +4
We have controlled the measurement strength of the qubit readout process by using a Josephson bifurcation amplifier (JBA : an AC-driven SQUID). The optimum readout pulse changes th…
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,…
Persistent Supercurrent Atom Chip
T. Mukai, C. Hufnagel, A. Kasper +4
Rubidium 87 atoms are trapped in an Ioffe-Pritchard potential generated with a persistent supercurrent that flows in a loop circuit patterned on a sapphire surface. The superconduc…
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…
