Description
I will introduce the recently developed quantum eigensolver algorithm based on optimized binary configurations measured by quantum annealing of D-Wave Advantage. The approach provides all energy specrum of L by L matrix with the computational cost of a linear increase in L, unlike exact diagonalization with L^3 iterations on classic computer. Using the method, I examined the energy dispersion of tight-binding Hamiltonian with two cases of metal and insulator. I wil show the comparasion between exact and
our results. I will also discuss the novel algorithm for optimized molecular structure based on classic optimizer and quantum annealing optimizer. Finally, I will show the detailed optimized structure on the H2 molecule
