Abstract

In \cite{JKS} we gave an (additive) categorification of Grassmannian cluster algebras, using the category \CM(A)\CM(A) of Cohen-Macaulay modules for a certain Gorenstein order AA. In this paper, using a cluster tilting object in the same category \CM(A)\CM(A), we construct a compatible pair (B,L)(B, L), which is the data needed to define a quantum cluster algebra. We show that when (B,L)(B, L) is defined from a cluster tilting object with rank 1 summands, this quantum cluster algebra is (generically) isomorphic to the corresponding quantum Grassmannian.
