The Ueda Group has joined a new international collaborative research project through the Japan Science and Technology Agency (JST) LOTUS Programme.

The project, entitled “Sector-Wise Structural Optimization for Tree Tensor Networks”, is jointly led by Hiroshi Ueda at The University of Osaka and Siddhartha Patra at the Centre for Quantum Engineering, Research and Education (CQuERE), TCG CREST, India.

Sayantan Dey, a Research Fellow at CQuERE, will participate in the project through the LOTUS Programme and conduct collaborative research in Japan.

The collaboration aims to advance structural optimization methods for tree tensor networks while strengthening research exchange between Japan and India.
