Quantum chemistry on quantum computers has attracted much attention as a promising target of near-term quantum devices. Quantum chemistry solves the time-independent Schrödinger equation of electrons and researches using quantum computer are well investigated. On the other hand, time-dependent Schrödinger equation (TDSE) on quantum computers is less investigated. In this contribution, we report the IBM Qiskit implementation of the recently developed TD-OUCC method (time-dependent optimized unitary coupled-cluster: a quantum/classical hybrid simulator of multielectron dynamics) and its application to electron dynamics in one-dimensional helium model using the real quantum computer installed at Kawasaki in 2021.
