Yujin Cho is a quantum physicist, working as a postdoctoral researcher in the Quantum Coherent Device Physics group at LLNL. Yujin graduated with a B.S. in Mathematics and Physics at Sogang University in South Korea in 2011 and M. S. in Physics in 2013 at the same institution, focusing on light-matter interaction on various 2D materials. Yujin completed her Ph. D. at the University of Texas at Austin in 2019 on nonlinear optical properties of ferroelectric materials. Before joining LLNL in 2021, she worked at University of California, Los Angeles, where she started her journey in quantum. Her research interests include understanding two level system defects on superconducting devices and optimal control.
