Spin Hall effect and Berry curvature of gravitons from quantum field theory
Ritsuki Ito, Kazuya Mameda, Naoki Yamamoto
Based on quantum field theory of linearized gravity, we formulate the Wigner function for right- and left-handed gravitons. By applying the Wigner transformation to the second-orde…

Quantum phase classification via partial tomography-based quantum hypothesis testing
Akira Tanji, Hiroshi Yano, Naoki Yamamoto
Quantum phase classification is a fundamental problem in quantum many-body physics, traditionally approached using order parameters or quantum machine learning techniques such as q…

Statistical inference for quantum singular models
Hiroshi Yano, Yota Maeda, Naoki Yamamoto
Deep learning has seen substantial achievements, with numerical and theoretical evidence suggesting that singularities of statistical models are considered a contributing factor to…
