The atom-optics kicked rotor can be used to prepare specific momentum distributions on a discrete basis set. We implement a continuous-time quantum walk (QW) and a quantum search protocol in this momentum basis. In particular we propose ways to identify a specific marked state from the final momentum distribution after the walker’s evolution. Our protocol is guided by current experimental possibilities making it accessible to experimentally implemented QWs with Bose–Einstein condensates.
