Activities

We investigate emergent quantum phenomena in hybrid electrical and mechanical systems engineered from low-dimensional condensed matter platforms, including graphene and carbon nanotubes.

Our research explores the quantum frontier of mesoscopic physics, where mechanical motion, an electronic qubit, and cavity microwave photons interact quantum mechanically, enabling quantum control of massive mechanical motion. In the ultrastrong dispersive regime, giant mechanical Kerr nonlinearities and enhanced zero-point fluctuations reshape mechanical motion. This opens routes toward long-coherence mechanical qubits, strongly non-Gaussian states with large spatial delocalization, and novel architectures for quantum sensing and quantum information processing.

In parallel, we investigate strongly correlated and topological electronic states in systems such as twisted bilayer graphene and other low-dimensional crystalline materials, aiming to uncover new collective quantum phases and transport mechanisms.
