Our interest lie in the physics of spin-based quantum computing platforms. We work on electrostatically-gated quantum dot qubits, donor-based spin qubits and spin qubits coupled via circuit quantum electrodynamics. Some of our representative research work are:
Gated quantum dot qubits : npj Quant. Inf. 7, 112 (2021)
Donor qubits : Adv. Mater. 2405916 (2024)
Spin-circuit QED : arXiv:2404.06187
Spin-based quantum sensors : Phys. Rev. Lett. 132, 266801 (2024)
We are interested in studying non-Markovian master equations from first principles when open quantum systems are strongly driven. As quantum computers progress towards fault-tolerance, non-Markovian quantum processes arising from cleaner and more structured environments become important. We are also interested in bosonic codes in circuit QED systems and error correction with high-dimensional spins. Some of our representative research work are:
Information backflow : arXiv:2501.09374
Noise characterization and tomography: Nature 511, 70 (2014)
We are interested in quantum foundational questions around the emergence of classicality and contextuality through quasiprobabilities. Research work in this area is coming soon.
Our research focusses on the epistemic dimensions of teaching and learning in physics. We study how students learn physics, how they make sense of uncertainty, and how encountering the boundaries of scientific knowledge can support deeper learning. As generative AI transforms classrooms, we are also examining how these tools affect students’ ability to think, inquire, and act as epistemic agents. Some of our representative research work are:
