Isaac H. Kim

I work in the field of Quantum Information and Quantum Computation. My research goal is to understand fundamental aspects of quantum entanglement that appear in nature. I have a fairly broad interest in anything quantum. I have worked on the following topics.

Topological Order
Quantum Error Correction
Quantum Algorithms
Black-hole information paradox
Matrix Analysis

These days, I am primarily focused on these topics.

Entanglement bootstrap program
Practical aspects of quantum error correction
Quantum algorithms for many-body quantum systems
