Zhen Qin
Hello, I am Zhen Qin, a fourth-year PhD student in the Department of Computer Science and Engineering at Ohio State University.
I am privileged to be under the guidance of Prof. Zhihui Zhu.
My current research encompasses several intriguing domains:
Quantum information, Quantum tomography,
Structured optimization for tensor decomposition, signal processing and communication,
Special structures of high-dimensional space including sparse, low-rank, manifold-based and tensor networks-based models.
My research is situated at the intersection of optimization, signal processing and quantum information theory.
It is dedicated to unraveling and comprehending foundational, computational,
and theoretical challenges within the domain of quantum information, achieved
through methodologies from optimization, signal processing, and classical information theory.
