Open-access review of phase-qubit device physics, control, tunneling readout, coupled-qubit experiments, fabrication, and the known decoherence mechanisms at the architecture’s experimental peak.
Key Results
- Derives the tilted-washboard and shallow-cubic-well operating picture
- Reviews phase-qubit energy relaxation, dephasing, and tunneling-readout errors
- Reports approximately 90% routine measurement fidelity and a roughly 96% ideal contrast limit for typical escape-rate ratios
