      abstract     = {Quantum computing provides a novel avenue towards
                      simulating dynamical phenomena, and, in particular,
                      scattering processes relevant for exploring the structure of
                      matter. However, preparing and evolving particle wave
                      packets on a quantum device is a nontrivial task. In this
                      work, we propose a method to prepare Gaussian wave packets
                      with momentum on top of the interacting ground state of a
                      fermionic Hamiltonian. Using Givens rotation, we show how to
                      efficiently obtain expectation values of observables
                      throughout the evolution of the wave packets on digital
                      quantum computers. We demonstrate our technique by applying
                      it to the staggered lattice formulation of the Thirring
                      model and studying the scattering of two wave packets.
                      Monitoring the particle density and the entropy produced
                      during the scattering process, we characterize the
                      phenomenon and provide a first step towards studying more
                      complicated collision processes on digital quantum
                      computers. In addition, we perform a small-scale
                      demonstration on IBM's quantum hardware, showing that our
                      method is suitable for current and near-term quantum
                      devices.},
