Circuit growth and subspace read-out in quantum-selected configuration interaction: Separating the Hartree-Fock determinant
Ayaka Fujimoto, Norifumi Matsumoto, Shota Kanasugi +2
Predicting many molecular properties requires accurate ground-state energies of molecular Hamiltonians. Quantum-selected configuration interaction (QSCI) obtains such energies by m…
Mirror subspace diagonalization: A real-time quantum Krylov algorithm with near-optimal sampling cost
Shota Kanasugi, Yuya O. Nakagawa, Norifumi Matsumoto +3
Quantum Krylov algorithms are a promising approach for ground-state energy estimation on near-term quantum computers. However, their sampling cost is inherently high because each H…
Provably scalable learning from quantum many-body data via locality
Koki Chinzei, Quoc Hoan Tran, Norifumi Matsumoto +2
Machine learning (ML) holds great promise for extracting insights from complex quantum many-body data obtained in quantum experiments, potentially solving certain classically intra…
Fast-forwardability of Qubit-mapped Fermion models based on Cartan decomposition
Yuichiro Hidaka, Shoichiro Tsutsui, Shota Kanasugi +3
We study the Hamiltonian algebra of qubit-mapped interacting fermion models and their fast-forwardability. We prove that the dimension of the Hamiltonian algebra of the fermion mod…
Quantum many-body simulation of finite-temperature systems with sampling a series expansion of a quantum imaginary-time evolution
