We establish a new Howe duality between a pair of quantum queer superalgebras (U q− 1 (q n), U q (q m)). The key ingredient is the construction of a non-commutative analogue A q (q n, q m) of the symmetric superalgebra S (C m n| m n) with the use of quantum coordinate queer superalgebra. It turns out that this superalgebra is equipped with a U q− 1 (q n)⊗ U q (q m)-supermodule structure that admits a multiplicity-free decomposition. We also show that the (U q− 1 (q n), U q (q m))-Howe duality implies the Sergeev-Olshanski duality.
