A frequency and sensitivity tunable microresonator array for high-speed quantum processor readout
J. D. Whittaker, L. J. Swenson, M. H. Volkmann +18
Superconducting microresonators have been successfully utilized as detection elements for a wide variety of applications. With multiplexing factors exceeding 1,000 detectors per tr…
Architectural considerations in the design of a superconducting quantum annealing processor
P. I. Bunyk, E. Hoskinson, M. W. Johnson +7
We have developed a quantum annealing processor, based on an array of tunably coupled rf-SQUID flux qubits, fabricated in a superconducting integrated circuit process [1]. Implemen…
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…
Tunneling spectroscopy using a probe qubit
A. J. Berkley, A. J. Przybysz, T. Lanting +15
We describe a quantum tunneling spectroscopy technique that requires only low bandwidth control. The method involves coupling a probe qubit to the system under study to create a lo…
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…
