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…
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 quantum selected configuration interaction
