Entanglement in a quantum annealing processor
T. Lanting, A. J. Przybysz, A. Yu. Smirnov +23
Entanglement lies at the core of quantum algorithms designed to solve problems that are intractable by classical approaches. One such algorithm, quantum annealing (QA), provides a…
A Near-Term Quantum Computing Approach for Hard Computational Problems in Space Exploration
Vadim N. Smelyanskiy, Eleanor G. Rieffel, Sergey I. Knysh +5
In this article, we show how to map a sampling of the hardest artificial intelligence problems in space exploration onto equivalent Ising models that then can be attacked using qua…
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…
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…
