  As a crossover frontier of physics and mechanics, quantum computing is
showing its great potential in computational mechanics. However, quantum
hardware noise remains a critical barrier to achieving accurate simulation
results due to the limitation of the current hardware level. In this paper, we
integrate error-mitigated quantum computing in data-driven computational
mechanics, where the zero-noise extrapolation (ZNE) technique is employed to
improve the accuracy of quantum computing. Numerical examples including
multiscale simulation of a composite L-shaped beam are conducted with the
quantum computer simulator Qpanda, and the results validate the effectiveness
of the proposed method. We believe this work presents a promising step towards
using the power of quantum computing in computational mechanics.
