We establish ring isomorphisms between quantum Grothendieck rings of certain remarkable monoidal categories C Q, B n and C Q, A 2 n− 1 of finite-dimensional representations of quantum affine algebras of types B n (1) and A 2 n− 1 (1), respectively. Our proof relies in part on the corresponding quantum cluster algebra structures. Moreover, we prove that our isomorphisms specialize at t= 1 to the isomorphisms of (classical) Grothendieck rings obtained recently by Kashiwara, Kim and Oh by other methods. As a consequence, we prove a conjecture formulated by the first author in 2002: the multiplicities of simple modules in standard modules in C Q, B n are given by the specialization of certain analogues of Kazhdan-Lusztig polynomials and the coefficients of these polynomials are positive.
