Abstract
The radial basis function (RBF) method is widely used for the numerical solution of the Poisson problem in high dimension, where the approximate solution can be found by solving a large system of linear equations. We demonstrate that the RBF method can be accelerated on a quantum computer by using an efficient quantum algorithm for linear equations. We compare the theoretical performance of our quantum algorithm with that of a standard classical algorithm, and find that the quantum algorithm can achieve a polynomial speedup.
