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…

Symmetry-Adapted State Preparation for Quantum Chemistry on Fault-Tolerant Quantum Computers

Viktor Khinevich, Wataru Mizukami

We present systematic and resource-efficient constructions of continuous symmetry projectors, particularly particle number and total spin, tailored for fault-toleran…

Enhancing quantum computations with the synergy of auxiliary field quantum Monte Carlo and computational basis tomography

Viktor Khinevich, Wataru Mizukami

We introduce QC-CBT-AFQMC, a hybrid algorithm that incorporates computational basis tomography (CBT) into the quantum-classical auxiliary-field quantum Monte Carlo (QC-AFQMC) metho…

Coupled cluster method tailored by quantum selected configuration interaction

Luca Erhart, Yuichiro Yoshida, Wataru Mizukami

We present the quantum-selected configuration interaction-tailored coupled-cluster (QSCI-TCC) method, a hybrid quantum-classical scheme that tailors coupled-cluster (CC) theory wit…

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…
