Dielectric surface loss in superconducting resonators with flux-trapping holes
B. Chiaro, A. Megrant, A. Dunsworth +18
Surface distributions of two level system (TLS) defects and magnetic vortices are limiting dissipation sources in superconducting quantum circuits. Arrays of flux-trapping holes ar…
Chiral groundstate currents of interacting photons in a synthetic magnetic field
P. Roushan, C. Neill, A. Megrant +22
The intriguing many-body phases of quantum matter arise from the interplay of particle interactions, spatial symmetries, and external fields. Generating these phases in an engineer…
Scalable in-situ qubit calibration during repetitive error detection
J. Kelly, R. Barends, A. G. Fowler +19
We present a method to optimize qubit control parameters during error detection which is compatible with large-scale qubit arrays. We demonstrate our method to optimize single or t…
Ergodic dynamics and thermalization in an isolated quantum system
C. Neill, P. Roushan, M. Fang +19
Statistical mechanics is founded on the assumption that all accessible configurations of a system are equally likely. This requires dynamics that explore all states over time, know…
