Automatic quantum circuit encoding of a given arbitrary quantum state
Tomonori Shirakawa, Hiroshi Ueda, Seiji Yunoki
We propose a quantum-classical hybrid algorithm to encode a given arbitrarily quantum state onto an optimal quantum circuit with a finite numbe…
Numerical analysis of the efficiency of face masks for preventing droplet airborne infections
Keiji Onishi, Akiyoshi Iida, Masashi Yamakawa +1
In this study, the flow field around face masks was visualized and evaluated using computational fluid dynamics. The protective efficiency of face masks suppressing droplet infecti…
Universal and Non-Universal Correction Terms of Bose Gases in Dilute Region: a Quantum Monte Carlo Study
Akiko Masaki-Kato, Yuichi Motoyama, Naoki Kawashima
We study dilute gases of interacting bosons at zero-temperature in the region where the system is characterized only by the s-wave scattering length. We carry out quantum Monte Car…
Grouped star formation: converting sink particles to stars in hydrodynamical simulations
K. Y. Liow, S. Rieder, C. L. Dobbs +1
Modelling star formation and resolving individual stars in numerical simulations of molecular clouds and galaxies is highly challenging. Simulations on very small scales can be suf…
Spatial, spin, and charge symmetry projections for a Fermi-Hubbard model on a quantum computer
Kazuhiro Seki, Seiji Yunoki
We propose an extended version of the symmetry-adapted variational-quantum-eigensolver (VQE) and apply it to a two-component Fermi-Hubbard model on a bipartite lattice. In the exte…
High pressure hydrogen by machine learning and quantum Monte Carlo
Andrea Tirelli, Giacomo Tenti, Kousuke Nakano +1
We have developed a technique combining the accuracy of quantum Monte Carlo in describing the electron correlation with the efficiency of a Machine Learning Potential (MLP). We use…
