Abstract
We develop a general framework for verifying stabilizer code subspaces with local measurements. Strategies based on stabilizer generators and groups apply broadly, while tailored coloring and XZ strategies for graph and CSS code subspaces reduce both measurement settings and sample cost. The protocols are nonadaptive, use a limited set of Pauli measurements, work for mixed states, and support the certification of logical states and logical operations.

Associate Researcher

I am an Associate Researcher and Outstanding Young Talent in the College of Computer Science and Technology, National University of Defense Technology (NUDT).

My research develops practical foundations for reliable and scalable quantum information processing. I work across photonic quantum computing, quantum characterization, verification and validation, distributed quantum estimation, and quantum information theory.

Before joining NUDT, I was a Senior Researcher at the Institute for Quantum Computing, Baidu Research, from 2020 to 2023. I led the development of the Quantum Error Processing (QEP) toolkit for characterizing, mitigating, and correcting errors in quantum devices through software. I received the Shenzhen Industrial Development and Innovation Talent Award in 2023.

Previously, I was a postdoc at the Shenzhen Institute for Quantum Science and Engineering (SIQSE), Southern University of Science and Technology, where I worked with Prof. Masahito Hayashi.
