Chebyshev Approximated Variational Coupled Cluster for Quantum Computing

Autor: Erhart, Luca, Yoshida, Yuichiro, Khinevich, Viktor, Mizukami, Wataru

We propose an approach to approximately implement the variational coupled cluster (VCC) theory on quantum computers, which struggles with exponential scaling of computational costs on classical computers. To this end, we employ expanding the exponent

Ab initio extended Hubbard model of short polyenes for efficient quantum computing

Autor: Yoshida, Yuichiro, Takemori, Nayuta, Mizukami, Wataru

We propose introducing an extended Hubbard Hamiltonian derived via the ab initio downfolding method, which was originally formulated for periodic materials, towards efficient quantum computing of molecular electronic structure calculations. By utiliz

Coupled cluster method tailored with quantum computing

Autor: Erhart, Luca, Yoshida, Yuichiro, Khinevich, Viktor, Mizukami, Wataru

Introducing an active space approximation is inevitable for the quantum computations of chemical systems. However, this approximation ignores the electron correlations related to non-active orbitals. Here, we propose a computational method for correc

A comprehensive survey on quantum computer usage: How many qubits are employed for what purposes?

Publikováno v: Nat. Rev. Phys. 6, 345 (2024)

Quantum computers (QCs), which work based on the law of quantum mechanics, are expected to be faster than classical computers in several computational tasks such as prime factoring and simulation of quantum many-body systems. In the last decade, rese

Solvent distribution effects on quantum chemical calculations with quantum computers

Autor: Yoshida, Yuichiro, Mizukami, Wataru, Yoshida, Norio

We present a combination of three-dimensional reference interaction site model self-consistent field (3D-RISM-SCF) theory and the variational quantum eigensolver (VQE) to consider the solvent distribution effects within the framework of quantum-class
