Correction scheme for molecular total energies from quantum phase estimation under limited qubit resources
Nobuki Inoue, Hisao Nakamura
We propose a practical method for accurately evaluating molecular total energies using a hybrid approach that integrates fault-tolerant quantum computers with classical computing.…

Theoretical examination of QED Hamiltonian and negative-energy orbitals in relativistic molecular orbital theory
Nobuki Inoue, Yoshihiro Watanabe, Haruyuki Nakano
The relativistic Hartree-Fock and electron correlation methods without the negative-energy orbital problem are examined on the basis of the quantum electrodynamics (QED) Hamiltonia…

Probing embedded topological modes in bulk-like GeTe-SbTe heterostructures
Hisao Nakamura, Johannes Hofmann, Nobuki Inoue +5
The interface between topological and normal insulators hosts metallic states that appear due to the change in band topology. While these topological states at a surface, i.e., a t…
