• We introduce an efficient variational method to solve the three-dimensional Schrodinger equation for any arbitrary potential V(x, y, z). The method uses a basis set of localized functions which are build up as a product of three one-dimensional cubic β-splines. We have analysed the accuracy of such a method by studying some exact 3D potentials: the harmonic oscillator, the hydrogen atom and the quantum box. Finally, we have calculated energy levels of GaA_S/AIGaA_S cubic quantum dots and make a comparison with the ones resulting from two well known simplification schemes based in a decomposition of the full potential problem into three separated one-dimensional problems. We show that the scheme making a sequential decomposition gives eingenvalues in better agreement with exact values here obtained variationally.
