Quantum Computational Resources and Conformal Field Theory: Unifying Spins, Bosons, and Fermions
Ryota Matsuda, Masahiro Hoshino, Yuto Ashida
Characterizing a quantum state through the lens of quantum resources provides an information-theoretic perspective on many-body systems. While quantum entanglement serves as the pa…
Stabilizer Rényi Entropy Encodes Fusion Rules of Topological Defects and Boundaries
Masahiro Hoshino, Yuto Ashida
We demonstrate that the stabilizer Rényi entropy (SRE), a computable measure of quantum magic, can serve as an information-theoretic probe for universal properties associated with…
Stabilizer Rényi Entropy and Conformal Field Theory
Masahiro Hoshino, Masaki Oshikawa, Yuto Ashida
Understanding universal aspects of many-body systems is one of the central themes in modern physics. Recently, the stabilizer Rényi entropy (SRE) has emerged as a computationally t…
Entanglement swapping in critical quantum spin chains
Masahiro Hoshino, Masaki Oshikawa, Yuto Ashida
The transfer of quantum information between many-qubit states is a subject of fundamental importance in quantum science and technology. We consider entanglement swapping in critica…
Nanodiamond quantum thermometry assisted with machine learning
Kouki Yamamoto, Kensuke Ogawa, Moeta Tsukamoto +3
Nanodiamonds (NDs) are quantum sensors that enable local temperature measurements, taking advantage of their small size. Though the model based analysis methods have been used for…
Generative diffusion model with inverse renormalization group flows
Kanta Masuki, Yuto Ashida
Diffusion models represent a class of generative models that produce data by denoising a sample corrupted by white noise. Despite the success of diffusion models in computer vision…
