Current Research
- My research team focuses on the experimental realisation of solid-state qubits hosted in low-dimensional material systems, e.g. 2D semiconductors, 2DEG (2D electron gas), etc. A critical bottleneck is the lack of high-quality materials for reproducible production of reliable qubits. My team is therefore invested in achieving the necessary “quantum-grade” material needed in order to reduce the significant wastage caused by low device yields due to material quality issues. Our ultimate goal is in achieving reproducible and reliable spin-based qubits in solid-state systems.
