In this paper, we classify holomorphic curves in Qn with certain geometric conditions. We study the (1,0) part of kth covariant derivative about the second fundamental form denoted by a,k, 0≤k≤[n2]-2; the norm of its symmetric product is denoted by τk= | a,k· a,k|. It is proven that a holomorphic curve in Qn is homogeneous if the Gaussian curvature, the norm of the second fundamental form and τk are all constant. Moreover, all the homogeneous holomorphic curves are uniquely determined by our given examples, up to a rigid motion of Qn.
