q-DNA

Quantum Data Science & AI @ Yonsei University

Welcome to the Quantum Data Science & AI (a.k.a q-DNA) lab at Yonsei University.

We are a multi-disciplinary group where expertise in statistics, physics, computer science, and applied mathematics intersect.

In brief, here is what we do:

Harness quantum information theory to solve various challenges in data science and AI.
Develop industrial applications of quantum computing empowered by quantum optimization techniques.
Develop statistical and machine learning methods that combat noise and imperfections in quantum information processing tasks.

For post-doctoral research positions, please contact the professor directly if you are interested in joining the team.

Currently, there are no openings for students.
