  We give a complete classification of isomorphism classes of finitely
generated projective modules, or equivalently, unitary equivalence classes of
projections, over the C*-algebra $C\left( \mathbb{S}_{q}^{2n+1}\right) $ of the
quantum homogeneous sphere $\mathbb{S}_{q}^{2n+1}$. Then we explicitly identify
as concrete elementary projections the quantum line bundles $L_{k}$ over the
quantum complex projective space $\mathbb{C}P_{q}^{n}$ associated with the
quantum Hopf principal $U\left( 1\right) $-bundle $\mathbb{S}
_{q}^{2n+1}\rightarrow\mathbb{C}P_{q}^{n}$.
