1. Tensor renormalization group and application to elementary particle physics

Prof. Shinji Takeda

12/11/24, 9:30 AM

Tensor network is a powerful numerical tool to compute the wave function of quantum many-body systems and to directly evaluate the path integrals in quantum field theory. In this talk, I mainly explain the latter case in detail. After introducing the basics of the tensor network. I give an overview of its recent progress especially in elementary particle physics. As specific examples, I...

Prof. Yoshifumi Nakata

12/12/24, 1:30 PM

A central challenge in large-scale quantum information processing is
managing noise in quantum systems. Quantum error correction (QEC)
addresses this by encoding quantum states into quantum error
correction codes (QECCs) before noise occurs and decoding them
afterward. Recently, QEC has attracted significant attention in
theoretical physics due to its potential connections to...
