Quantum Algorithm for Method of Moment in Electromagnetic Computation

We propose a quantum algorithm for method of moments (MOM) that is able to efficaciously calculate the relative surface current density and electromagnetic radar cross section (RCS) problem for electrically large size targets. This quantum algorithm can be implemented by the dense Hamiltonian simulation technology and the method of solving the inverse of the dense matrix. We put forward a feasible algorithm for the dense Hamiltonian simulation where a novel tree access structure is applied, and perform the Fourier approach to approximate to the inverse of the dense matrix with the result of gate complexity.
