A Quantum-HPC Hybrid Workflow for Reaction-Center Electronic Dynamics: Application to a Cytochrome P450-Inspired Iron-Complex Model
Shintaro Maekawa, Takao Otsuka, Riku Masui +4
We introduce population-transfer dynamics as a practical validation observable for active-space-derived reduced Hamiltonians in multistate reaction-center chemistry. Using a cytoch…

Computational Characterization of Symmetry-Protected Topological Phases in Open Quantum Systems
Riku Masui, Keisuke Totsuka
It is a challenging problem to correctly characterize the symmetry-protected topological (SPT) phases in open quantum systems. As the measurement-based quantum computation (MBQC) u…
