Explicit block encodings of rate matrices for simulating polymerization kinetics on quantum computers
Yuhei Ikeda, Hokuto Iwakiri, Soichiro Nishio +1
Predicting how molecular weight distribution and monomer sequence evolve during polymerization is central to polymer science, yet classical approaches face a trade-off between mole…
Fixing Divergence in Carleman Linearization via Analytical Continuation
Mingshuo Zhu, Hayato Higuchi, Hokuto Iwakiri +4
Nonlinear differential equations play a crucial role in modeling a wide range of phenomena, yet their solutions remain notoriously difficult to obtain. With the rapid development o…
On universality of hardware-efficient ansatzes
Hokuto Iwakiri, Keita Kanno
The hardware-efficient ansatz (HEA) is one of the most important class of parametrized quantum circuits for near-term applications of quantum computing. We show that the problem of…
Hardness of classically sampling quantum chemistry circuits
Ayoub Hafid, Hokuto Iwakiri, Kento Tsubouchi +2
Significant advances have been made in the study of quantum advantage both in theory and experiment, although these have mostly been limited to artificial setups. In this work, we…
Quantum computation of a quasiparticle band structure with the quantum-selected configuration interaction
Takahiro Ohgoe, Hokuto Iwakiri, Kazuhide Ichikawa +2
Quasiparticle band structures are fundamental for understanding strongly correlated electron systems. While solving these structures accurately on classical computers is challengin…
Enhancing Accuracy of Quantum-Selected Configuration Interaction Calculations using Multireference Perturbation Theory: Application to Aromatic Molecules
Soichi Shirai, Shih-Yen Tseng, Hokuto Iwakiri +3
Quantum-selected configuration interaction (QSCI) is a novel quantum-classical hybrid algorithm for quantum chemistry calculations. This method identifies electron configurations h…
Demonstrating Quantum Computation for Quasiparticle Band Structures
Takahiro Ohgoe, Hokuto Iwakiri, Masaya Kohda +4
Understanding and predicting the properties of solid-state materials from first-principles has been a great challenge for decades. Owing to the recent advances in quantum technolog…
Computational analysis of chemical reactions using a variational quantum eigensolver algorithm without specifying spin multiplicity
Soichi Shirai, Hokuto Iwakiri, Keita Kanno +4
The analysis of a chemical reaction along the ground state potential energy surface in conjunction with an unknown spin state is challenging because electronic states must be separ…
