The shell model and quantum encoding. (a) Segrè chart covering the p, sd and part of the pf shell. Solid lines indicate neutron and proton magic numbers. Open circles show the isotopes studied in this work. (b) Schematic representation of the p-, sd- and pf-shell configuration spaces. The number on top of every single-particle state is the qubit label for the implementation in a quantum device under a Jordan–Wigner mapping. (c) Number of many-body configurations, \(\dim _\mathrm{{mb}}\), in the M-basis as a function of the number of active neutrons in the configuration space, \(N_\mathrm{{CI}}\). We show results for the isotopic chains of He and Be in the p shell; O, F, Ne, and Al in the sd shell; and Ca, Ti, Cr, and Zn in the pf shell. Isotopes beyond the middle of the shell are not shown since the number of configurations is symmetric. Bold marker lines highlight nuclei studied in this work.
