My research primarily focuses on the Optimization aspect of the Variational Quantum Eigensolver algorithm (VQE), a hybrid quantum-classical algorithm designed to find the ground-state energy of the Hamiltonian. I will examine the various algorithms to update the parameters from the approximation to exact and to the state-of-the-art Quantum Natural Gradient Descent algorithm. The Traversed Ising model, a well-known fermion model, serves as the test model for this research. Most of the results were obtained using Qiskit's simulator on a classical computer.
