• In this paper, we study the one-dimensional stationary Schrödinger equation with quasi-periodic potential $u(\omega t)$. We show that if the frequency vector $\omega$ is sufficient large, the Schrödinger equation admits two linear independent Floquet solutions for a set of positive measure of energy $E$. In contrast with previous results, the conditions of small potential $u$ or large energy $E$ are no longer needed.
