In a recent work (A quantumclassical coprocessing protocol towards simulating nuclear reactions on contemporary quantum hardware, arXiv:2302.06734), we proposed, in collaboration with the Nuclear Theory Group at LLNL and the AQT team at LBL, a scheme to simulate a nuclear reaction on a quantum computer from realistic interactions, and based on the Trotter breakup of the real time propagator. The first application was made on the scattering of two neutrons. We want now to proceed to the case of three nucleons, namely the neutrondeuteron scattering, which is a coupled channels problem. Depending on the energy, one can have the neutron capture by d, elastic nd scattering and the d breakup. In the thesis the student will be required to carry out the formal analysis enabling the encoding of the problem on a set of superconductive qdits, possibly making use of optimal control techniques.
