Hingergrund
S gnau Berächne vo chemische Reaktionsenergiene isch wichtig für wüsseschaftlichi Fortschritt i de Materialwüsseschaft, chemische Technik, Medikamenteentdeckig und andere Fälder. Under verschidene chemische System het s Li-S System viel Ufmerksamkeit übercho für s Verschtah und Entwickle vo neue Batterie-Zämmesetzige. Das Tutorial git praktischi Erfahrig bim Berächne vo de Li-S Bindigsdisoziations-Potentialenergieoberflächi (PES) vo emene System dur s Ewägnäh vo eim Lithium-Atom mit HiVQE Berächnige. D Resultat chönd mit Referänzberächnige (CASCI) und klassische Methode wie Hartree-Fock (HF) für es 20-Qubit-Problem vergliche werde.

HiVQE Berächnige werdet mit de Optione usgfüehrt, wo unne definiert sind. Mit sto3g Basis für gits 19 rüümlichi Orbitale mit 22 Elektrone. Zum Usfüehre vom (10o,10e) Fall mit HiVQE Berächnig chönd dir 10 aktivi Orbitale und sächs ygfrorne Orbitale definiere. Bi jeder Iteration werdet 100 Shots brucht zum Sample vo Elektronekonfiguratione, wo dur de ExcitationPreserving Quanteschaltkreis (epa) mit circular Verschränkig und zwei Widerholige (reps) generiert werdet. D maximali Zahl vo Iteratione isch uf 30 gsetzt zum Sicherschtelle vo Beändigig mit Energiekonvergänz.
