Dynamic quantum Kerr effect in circuit quantum electrodynamics
Yi Yin, H. Wang, M. Mariantoni +14
A superconducting qubit coupled to a microwave resonator provides a controllable system that enables fundamental studies of light-matter interactions. In the dispersive regime, pho…
Surface spin fluctuations probed with flux noise and coherence in Josephson phase qubits
Daniel Sank, R. Barends, Radoslaw C. Bialczak +15
We measure the dependence of qubit phase coherence and surface spin induced flux noise on inductor loop geometry. While wider inductor traces change neither the flux noise power sp…
Implementing the Quantum von Neumann Architecture with Superconducting Circuits
Matteo Mariantoni, H. Wang, T. Yamamoto +14
The von Neumann architecture for a classical computer comprises a central processing unit and a memory holding instructions and data. We demonstrate a quantum central processing un…
Surface loss simulations of superconducting coplanar waveguide resonators
J. Wenner, R. Barends, R. C. Bialczak +14
Losses in superconducting planar resonators are presently assumed to predominantly arise from surface-oxide dissipation, due to experimental losses varying with choice of materials…
Loss and decoherence due to stray infrared light in superconducting quantum circuits
R. Barends, J. Wenner, M. Lenander +14
We find that stray infrared light from the 4 K stage in a cryostat can cause significant loss in superconducting resonators and qubits. For devices shielded in only a metal box, we…
Phase qubits fabricated with trilayer junctions
M. Weides, R. C. Bialczak, M. Lenander +11
We have developed a novel Josephson junction geometry with minimal volume of lossy isolation dielectric, being suitable for higher quality trilayer junctions implemented in qubits.…
