Traveling wave parametric amplifier with Josephson junctions using minimal resonator phase matching
T. C. White, J. Y. Mutus, I. -C. Hoi +18
Josephson parametric amplifiers have become a critical tool in superconducting device physics due to their high gain and quantum-limited noise. Traveling wave parametric amplifiers…
Digital quantum simulation of fermionic models with a superconducting circuit
R. Barends, L. Lamata, J. Kelly +21
Simulating quantum physics with a device which itself is quantum mechanical, a notion Richard Feynman originated, would be an unparallelled computational resource. However, the uni…
UCSB final report for the CSQ program: Review of decoherence and materials physics for superconducting qubits
John M. Martinis, A. Megrant
We review progress at UCSB on understanding the physics of decoherence in superconducting qubits. Although many decoherence mechanisms were studied and fixed in the last 5 years, t…
Characterization and reduction of microfabrication-induced decoherence in superconducting quantum circuits
C. M. Quintana, A. Megrant, Z. Chen +18
Many superconducting qubits are highly sensitive to dielectric loss, making the fabrication of coherent quantum circuits challenging. To elucidate this issue, we characterize the i…
Observation of topological transitions in interacting quantum circuits
P. Roushan, C. Neill, Yu Chen +21
The discovery of topological phases in condensed matter systems has changed the modern conception of phases of matter. The global nature of topological ordering makes these phases…
