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 seniority-zero trial wave function
Yuichiro Yoshida, Luca Erhart, Takuma Murokoshi +4
We present an approach that uses the doubly occupied configuration interaction (DOCI) wave function as the trial wave function in phaseless auxiliary-field quantum Monte Carlo (ph-…

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…
