Implementation of a Quantum Annealing Algorithm Using a Superconducting Circuit
R. Harris, A. J. Berkley, J. Johansson +10
A circuit consisting of a network of coupled compound Josephson junction rf-SQUID flux qubits has been used to implement an adiabatic quantum optimization algorithm. It is shown th…
Synchronization of Multiple Coupled rf-SQUID Flux Qubits
R. Harris, F. Brito, A. J. Berkley +10
A practical strategy for synchronizing the properties of compound Josephson junction rf-SQUID qubits on a multiqubit chip has been demonstrated. The impacts of small () fab…
Geometrical dependence of low frequency noise in superconducting flux qubits
T. Lanting, A. J. Berkley, B. Bumble +11
A general method for directly measuring the low-frequency flux noise (below 10 Hz) in compound Josephson junction superconducting flux qubits has been used to study a series of 85…
Landau-Zener Transitions in an Adiabatic Quantum Computer
J. Johansson, M. H. S. Amin, A. J. Berkley +7
We report an experimental measurement of Landau-Zener transitions on an individual flux qubit within a multi-qubit superconducting chip designed for adiabatic quantum computation.…
Probing Noise in Flux Qubits via Macroscopic Resonant Tunneling
R. Harris, M. W. Johnson, S. Han +13
Macroscopic resonant tunneling between the two lowest lying states of a bistable RF-SQUID is used to characterize noise in a flux qubit. Measurements of the incoherent decay rate a…
