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.…
Energy decay and frequency shift of a superconducting qubit from non-equilibrium quasiparticles
M. Lenander, H. Wang, Radoslaw C. Bialczak +12
Quasiparticles are an important decoherence mechanism in superconducting qubits, and can be described with a complex admittance that is a generalization of the Mattis-Bardeen theor…
