Abstract:

The quench dynamics of the Su-Schierffer-Heeger (SSH) chain is simulated on IBM Quantum computers. The second-order Rényi entanglement entropy, the twist order parameter and the Berry phase are calculated and shown persistent oscillations. Through error mitigation techniques, including global depolarizing error ansatz and postselection based on symmetry constraints, the simulation results match closely to the exact solution. Along with this research, a software tool is developed for effective simulation of entanglement entropy and a patent for monitoring quantum computers is granted.
