ZiYi Yang Presents FrontierLab Research on Failure-Aware Quantum Simulation
ZiYi Yang presented his FrontierLab research on light-cone-based quantum circuit learning for reliable real-time simulation of one-dimensional spin chains.
Research
The Ueda Group focuses on tensor network methods, quantum many-body physics, quantum algorithms, and quantum-classical hybrid computation.
We develop numerical and theoretical methods for strongly correlated systems, quantum entanglement, variational quantum computation, and quantum-HPC hybrid workflows.
Our research connects condensed matter physics, quantum information, and high-performance computing.
Research Topics
Tensor Networks: Development and optimization of tensor network methods for quantum and classical many-body systems.
