Title: Elastic and Inelastic Scattering on a Quantum Computer
Abstract: Scattering experiments are fundamental to understanding the microscopic structure of quantum objects. Scattering is a real-time process. However, realistic quantum many-body calculations on classical computers are usually limited to imaginary times. An algorithm for the real-time calculation of radiative, and in general inelastic processes such as charge exchange reactions, on a quantum computer is presented. We demonstrate the feasibility of the method by calculating the radiative E1 transition matrix element in a simple system on a quantum processor. Results for 2-particle elastic scattering amplitude are also presented.
