Each single-particle state in a shell is associated with a qubit in state |1⟩ if occupied and |0⟩ if empty. By employing the system’s Hamiltonian and utilizing the Jordan-Wigner mapping, creation and annihilation fermion operators are transformed into Pauli matrix terms, enabling their implementation in a quantum circuit through quantum gates. To simulate this system, an Adaptive Variational Quantum Eigensolver (ADAPT-VQE) is employed, which iteratively constructs a wavefunction that minimizes the energy at each step. Through repeated iterations, an upper bound for the ground state energy is obtained6 p.application/pdfengcc-by-nc-nd (c) Ramon, 2023http://creativecommons.org/licenses/by-nc-nd/3.0/es/Models nuclearsCircuits quànticsTreballs de fi de grauNuclear modelsQuantum circuitBachelor's thesesinfo:eu-repo/semantics/bachelorThesisinfo:eu-repo/semantics/openAccess
