Loss study of InAs-2DEG gatemons and their coplanar-waveguide resonators, showing how hybrid-material and resonator losses can dominate an otherwise scalable planar process.
Key Results
- Coherent Rabi oscillations and vacuum Rabi splitting in an InAs-2DEG gatemon.
- across a 1.5 GHz gate-tunable band in the reported process.
- Systematic resonator measurements identified concrete materials and fabrication directions for improving coherence.
