Let Q be any valued quiver without oriented cycles. We study connections between the category of valued representations of Q and expansions of cluster variables in terms of an initial cluster in quantum cluster algebras. We show that an analog of the Caldero–Chapoton formula holds for the specializations , where is a finite field, in all quantum cluster algebras of finite type, including nonsimply laced types, and for any cluster variable in an almost acyclic cluster.
