document: Quantum-state information retrieval in a Rydberg-atom data register We analyze a quantum search protocol to retrieve phase information from a Rydberg-atom data register using a subpicosecond half-cycle electric field pulse . Calculations show that the half-cycle pulse can perform the phase retrieval only within a range of peak field values . By varying the phases of the constituent orbitals of the Rydberg wave packet register , we demonstrate coherent control of the phase retrieval process . By specially programming the phases of the orbitals comprising the initial wave packet , we show that it is possible to use the search method as a way to synthesize single energy eigenstates
