抄録

Quantum simulation algorithm for the lattice fermions in the ground state is examined. Initial trial state is optimized using the unrestricted Hartree Fock solution. Convergence to the ground state average in the projection process is compared among several choices of the trial state. The optimized trial state provides a faster convergence for physical quantities as well as a better minus sign ratio in the sampling.
