  In this study, we investigate Trotter evolution in the Gross-Neveu and
hyperbolic Ising models in two spacetime dimensions, using quantum computers.
We identify different sources of errors prevalent in various quantum processing
units and discuss challenges to scale up the size of the computation. We
present benchmark results obtained on a variety of platforms and employ a range
of error mitigation techniques to address coherent and incoherent noise. By
comparing these mitigated outcomes with exact diagonalization results and
density matrix renormalization group calculations, we assess the effectiveness
of our approaches. Moreover, we demonstrate the implementation of an
out-of-time-ordered correlator (OTOC) protocol using IBM's quantum computers.
