Probing High Frequency Noise with Macroscopic Resonant Tunneling
T. Lanting, M. H. S. Amin, M. W. Johnson +9
We have developed a method for extracting the high-frequency noise spectral density of an rf-SQUID flux qubit from macroscopic resonant tunneling (MRT) rate measurements. The extra…
Observation of Co-tunneling in Pairs of Coupled Flux Qubits
T. Lanting, R. Harris, J. Johansson +17
We report measurements of macroscopic resonant tunneling between the two lowest energy states of a pair of magnetically coupled rf-SQUID flux qubits. This technique provides a dire…
Experimental Investigation of an Eight Qubit Unit Cell in a Superconducting Optimization Processor
R. Harris, M. W. Johnson, T. Lanting +23
A superconducting chip containing a regular array of flux qubits, tunable interqubit inductive couplers, an XY-addressable readout system, on-chip programmable magnetic memory, and…
Experimental Demonstration of a Robust and Scalable Flux Qubit
R. Harris, J. Johansson, A. J. Berkley +16
A novel rf-SQUID flux qubit that is robust against fabrication variations in Josephson junction critical currents and device inductance has been implemented. Measurements of the pe…
A scalable readout system for a superconducting adiabatic quantum optimization system
A. J. Berkley, M. W. Johnson, P. Bunyk +7
We have designed, fabricated and tested an XY-addressable readout system that is specifically tailored for the reading of superconducting flux qubits in an integrated circuit that…
Phenomenology of a-axis and b-axis charge dynamics from microwave spectroscopy of highly ordered YBa2Cu3O6.50 and YBa2Cu3O6.993
R. Harris, P. J. Turner, Saeid Kamal +9
Extensive measurements of the microwave conductivity of highly pure and oxygen-ordered \YBCO single crystals have been performed as a means of exploring the intrinsic charge dynami…
