QCSH: A full quantum computer nuclear shell-model package

The nuclear system is a promising area for demonstrating practical quantum advantage. A comprehensive computation of in classical computer beyond the capacity current computers. With rapid development hardware, prospect using computers physics close at hand. In this paper, we report full package, QCSH, solving shell model computer. QCSH uses linear combination unitary formalism computing and performs all calculations complexities qubit resource number basic gates are both polynomials to nucleons nuclei. For example, used calculate binding energies 12 light nuclei (i.e., 2H, 3H, 3He, 4He, 6Li, 7Li, 12C, 14N, 16O, 17O, 23Na, 40Ca). Moreover, experimentally demonstrate calculation deuteron energy superconducting processor. result indicates that can provide meaningful results already near-term devices.
