QSCI-CMP: Quantum-Selected Configuration Interaction with Chemically Motivated Preselection
Masahiko Kamoshita, Kosuke Mitarai
We present QSCI-CMP, a quantum-classical hybrid algorithm for molecular ground-state calculations that reduces both the query count and the gate count of sample-based quantum diago…
Evaluating higher-order product formulae for molecular ground-state energy estimation
Hiromu Abe, Keita Kanno, Ryosuke Kimura +2
We evaluate deterministic higher-order product formulae for molecular ground-state energy estimation. Motivated by recent fault-tolerant architectures in which non-Clifford operati…
Orbital-rotated Fermi-Hubbard model as a benchmarking problem for quantum chemistry with the exact solution
Ryota Kojima, Masahiko Kamoshita, Keita Kanno
Quantum chemistry is a key target for quantum computing, but benchmarking quantum algorithms for large molecular systems remains challenging due to the lack of exactly solvable yet…
ADAPT-QSCI: Adaptive Construction of an Input State for Quantum-Selected Configuration Interaction
Yuya O. Nakagawa, Masahiko Kamoshita, Wataru Mizukami +2
We present a quantum-classical hybrid algorithm for calculating the ground state and its energy of the quantum many-body Hamiltonian by proposing an adaptive construction of a quan…
