ABSTRACT: Classical
simulation of a quantum system is a hard problem. It’s known that these
problems can be solved efficiently by using quantum computers. This study
demonstrates the simulation of the molecular Hamiltonian of 2p-π electrons of
ethylene in order to calculate the ground state energy. The ground state energy
is estimated by an iterative phase estimation algorithm. The ground state is prepared by the adiabatic
state preparation and the implementation of the procedure is carried out by
numerical simulation of two-qubit NMR quantum simulator. The readout scheme of
the simulator is performed by extracting binary bits via NMR interferometer.
