Doubling the size of quantum selected configuration interaction based on seniority-zero space and its application to QC-QSCI-AFQMC
Yuichiro Yoshida, Takuma Murokoshi, Rika Nakagawa +6
We propose doubly occupied configuration interaction-quantum selected configuration interaction (DOCI-QSCI), which samples from the seniority-zero space. While the use of this spac…
Auxiliary-field quantum Monte Carlo method with quantum selected configuration interaction
Yuichiro Yoshida, Luca Erhart, Takuma Murokoshi +5
We propose using the wave function generated by the quantum selected configuration interaction (QSCI) method as the trial wave function in phaseless auxiliary-field quantum Monte C…
Chebyshev Approximated Variational Coupled Cluster for Quantum Computing
Luca Erhart, Yuichiro Yoshida, Viktor Khinevich +1
We propose an approach to approximately implement the variational coupled cluster (VCC) theory on quantum computers, which struggles with exponential scaling of computational costs…
Ab initio extended Hubbard model of short polyenes for efficient quantum computing
Yuichiro Yoshida, Nayuta Takemori, Wataru Mizukami
We propose introducing an extended Hubbard Hamiltonian derived via the ab initio downfolding method, which was originally formulated for periodic materials, towards efficient quant…
Coupled cluster method tailored with quantum computing
Luca Erhart, Yuichiro Yoshida, Viktor Khinevich +1
Introducing an active space approximation is inevitable for the quantum computations of chemical systems. However, this approximation ignores the electron correlations related to n…
