Efficient Quantum Circuits for Electronic Hamiltonian Simulation without Pauli Expansion
Tamiya Onodera, Takeshi Sato
Electronic Hamiltonian simulation is commonly formulated by mapping fermionic operators to qubit operators and subsequently expanding the resulting ladder-operator products into Pa…
Efficient simulation of multielectron dynamics in molecules under intense laser pulses: Implementation of the multiconfiguration time-dependent Hartree-Fock method based on the adaptive finite element method
Yuki Orimo, Takeshi Sato, Kenichi L. Ishikawa
We present an implementation of the multiconfiguration time-dependent Hartree-Fock method based on the adaptive finite element method for molecules under intense laser pulses. For…
Variational Quantum Simulation for Periodic Materials
Nobuyuki Yoshioka, Takeshi Sato, Yuya O. Nakagawa +2
We present a quantum-classical hybrid algorithm that simulates electronic structures of periodic systems such as ground states and quasiparticle band structures. By extending the u…
Analysis of strong-field enhanced ionization of molecules using Bohmian trajectories
Ryohto Sawada, Takeshi Sato, Kenichi L. Ishikawa
We theoretically investigate the mechanism of enhanced ionization in two-electron molecules by analyzing Bohmian trajectories for a one-dimensional H2 in an intense laser field. We…
