Adiabatic quantum computation with flux qubits, first experimental results
S. H. W. van der Ploeg, A. Izmalkov, M. Grajcar +10
Controllable adiabatic evolution of a multi-qubit system can be used for adiabatic quantum computation (AQC). This evolution ends at a configuration where the Hamiltonian of the sy…

Sign- and magnitude-tunable coupler for superconducting flux qubits
R. Harris, A. J. Berkley, M. W. Johnson +11
We experimentally confirm the functionality of a coupling element for flux-based superconducting qubits, with a coupling strength whose sign and magnitude can be tuned {\it in…

Low-frequency characterization of quantum tunneling in flux qubits
Ya. S. Greenberg, A. Izmalkov, M. Grajcar +5
We propose to investigate flux qubits by the impedance measurement technique (IMT), currently used to determine the current--phase relation in Josephson junctions. We analyze in de…
