Leeseok Kim
I’m a postdoctoral researcher at the University of New Mexico, based primarily in the Theoretical Division (T-4) at Los Alamos National Laboratory, where I work with Luis Pedro García-Pintos. I completed my PhD in Computer Engineering at the University of New Mexico under the supervision of Milad Marvian. Before that, I earned bachelor’s degrees in Physics and Mathematics from Cornell University.
These days, I mostly (though not exclusively) think about how quickly quantum systems thermalize and when randomization can improve quantum protocols. During my PhD, I focused on developing new ways to control quantum systems and protect them from noise. More broadly, I am interested in the theoretical aspects of quantum computing, including quantum algorithms, simulations, error suppression/correction, and open quantum systems.
