§01 / Research focus

Where I spend my time

Four threads I keep coming back to.

01

Mutual Information Maximizing Quantum GANs

Designing quantum generative adversarial networks that maximize mutual information to stabilize training and improve sample fidelity (Scientific Reports 15, 32835, 2025).

Quantum machine learning Generative models Quantum information
02

Disentangled Quantum Neural Networks

Building disentangled quantum neural networks for unified estimation of quantum entropies and distance measures (Physical Review A 110, 062418, 2024).

Quantum neural networks Entropy estimation Variational algorithms
03

AI-based ETF Managing

Developing transformer-based time-series models for low-cost ETF portfolio management and index tracking, extending AI-based ETF portfolio research from NCSOFT internship and competition work toward liquidity-aware strategies.
