Research & lead at a glance

Independent research lab led by HKUST MPhil Inho Choi, aligning tensor networks, Hamiltonian estimation, and systems engineering into credible research products.

HKUST MPhil researcher linking quantum information theory and tensor-network software

I'm pursuing an MPhil in Physics at HKUST (Adrian Po group), focused on quantum information theory, tensor-network modeling, and Hamiltonian estimation workflows that tie theory to controllable devices.

The path started in HKUST's BSc research track with the Entrance Scholarship, building simulators for NV centers, Rydberg platforms, and IBM Quantum challenges while mentoring as a Qiskit Advocate.

Across projects I push for research clarity and product polish—reproducible simulations, interactive visualizations, and instrumentation that let collaborators validate ideas quickly.
