Abstract: | We extend the proposal of Berenstein, Maldacena and Nastase to the Type IIB superstring propagating on a pp-wave over the

quiver gauge theory. We propose a precise map between gauge theory operators and string states for both untwisted and twisted
sectors. We also compute leading-order perturbative correction to the anomalous dimensions of these operators. The result
is in agreement with the value deduced from the string energy spectrum, thus substantiating our proposed operator-state map.
