Abstract
U ovom radu istražujemo algoritamske pristupe primjenjive na kvantne sustave, posebno Fermi-Hubbardov model. Uz povijesni osvrt i motivaciju, dan je i kratki pregled potrebnih fizikalnih i računalnih koncepata. Nakon što je model predstavljen i neki od njegovih rubnih slučajeva analitički riješeni, pokazujemo kako koristiti klasične i kvantne simetrije da bismo njegov Hamiltonijan reducirali na lako rješive blokove. Intuicija i razumijevanje izgrađeni u ovom dijelu omogućavaju nam da postupno izgradimo ansatz za kvantni varijacijski algoritam. Nakon konstrukcije sklopa, provodimo simulacije koje otkrivaju da predloženo rješenje radi precizno s različitim optimizatorima, izvršava se u kratkom vremenu te je robusno na uvođenje šuma koji potječe od konačnog broja mjerenja. Konačno, ističemo nekoliko prirodnih smjerova za buduća istraživanja.
Abstract (english)
In this work, we explore algorithmic approaches applicable to quantum systems, specifically the Fermi-Hubbard model. After outlining the motivation to do so, we follow with a brief overview of necessary physical and computing concepts. Once the model is introduced and some of its limiting cases are solved analytically, we demonstrate how to use classical and quantum symmetries to reduce its Hamiltonian into easily solvable blocks. The intuition and understanding built doing so allow us to gradually build the quantum ansatz for the Variational Quantum Eigensolver. After constructing the circuit, we conduct simulations, revealing that the proposed solution works precisely with various optimizers and runs in a short time, all while being robust even when the shot noise is introduced. Finally, we outline some natural directions for future research.
