    Abstract: In this work, we simulate the quench dynamics of the Su–Schrieffer–Heeger model on noisy intermediate-scale quantum (NISQ) computers. In particular, the second-order Renyi entropy is probed by randomized measurement on IBMQ platforms. In order to efficiently process the large-scale quantum circuits and data from randomized measurement, we have developed a tool, Qurry, for job managements, parallel computation and the Trotter decomposition with adaptive step size. We consider the fully dimerized limit of the quench Hamiltonian. In this limit, the time evolution operator can be exactly mapped to quantum gates; thus, the effect of noise is reduced. The oscillation patterns of the entanglement entropy agree well with theory after error mitigation.
