Classically Driven Hybrid Quantum Algorithms with Sequential Givens Rotations for Reduced Measurement Cost
Benjamin Mokhtar, Noboru Inoue, Takashi Tsuchimochi
Quantum algorithms for electronic-structure simulations are actively being developed, yet many hybrid quantum-classical approaches are bottlenecked by the measurement overhead asso…
Improved algorithms of quantum imaginary time evolution for ground and excited states of molecular systems
Takashi Tsuchimochi, Yoohee Ryo, Seiichiro L. Ten-no
Quantum imaginary time evolution (QITE) is a recently proposed quantum-classical hybrid algorithm that is guaranteed to reach the lowest state of system. In this study, we present…
Multi-state quantum simulations via model-space quantum imaginary time evolution
Takashi Tsuchimochi, Yoohee Ryo, Siu Chung Tsang +1
We introduce the framework of model space into quantum imaginary time evolution (QITE) to enable stable estimation of ground and excited states using a quantum computer. Model-spac…
Adaptive construction of shallower quantum circuits with quantum spin projection for fermionic systems
Takashi Tsuchimochi, Masaki Taii, Taisei Nishimaki +1
Quantum computing is a promising approach to harnessing strong correlation in molecular systems; however, current devices only allow for hybrid quantum-classical algorithms with a…
