We prove a quantum version of Kalkman's wall-crossing formula comparingGromov-Witten invariants on geometric invariant theory (git) quotients relatedby a change in polarization. The wall-crossing terms are gauged Gromov-Witteninvariants with smaller structure group. As an application, we show that thegraph Gromov-Witten potentials of quotients related by wall-crossings ofcrepant type are equivalent up to a distribution in the quantum parameter thatis almost everywhere zero. This is a version of the crepant transformationconjecture of Li-Ruan, Bryan-Graber, Coates-Ruan etc. in cases where thecrepant transformation is obtained by variation of git.
