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…
