• (Ongoing) Correcting the Chiral Central Charge in Entanglement‑Area‑Law Violations

  PI: Prof. Gilyoung Cho (KAIST)
  2025 – Present

  Topologically ordered phases in (2+1)‑D are characterised by the chiral central charge c₋. Numerical extractions overshoot when the state only approximately obeys an area law. I investigate the leading error term of c₋ as a function of system size when small violations of the area law are allowed.

• (Ongoing) Thermal Operations vs. Gibbs‑Preserving Covariant Channels

  PI: Prof. Nelly Ng (NTU Singapore)
  2024 – 2025

  For systems with non‑degenerate energy gaps, I aim to prove that the set of states reachable under Gibbs‑preserving covariant channels coincides with those reachable via Thermal Operations, and to analyse the complexity of deciding TO‑reachability.

• Rydberg‑Atom Graphs for Quadratic Unconstrained Binary Optimisation

  PI: Prof. Jae Wook Ahn (KAIST)
  2023

  Developed a general method to construct a Rydberg‑atom graph whose Hamiltonian realises an arbitrary QUBO function without requiring individual qubit detuning by using offset qubits and quantum wires. Published in Adv. Quantum Technol. 2024.
