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 control system for a superconducting adiabatic quantum optimization processor
M. W. Johnson, P. Bunyk, F. Maibaum +10
We have designed, fabricated and operated a scalable system for applying independently programmable time-independent, and limited time-dependent flux biases to control superconduct…
