Physical Review A - Atomic, Molecular, and Optical Physics
The connections between the phase retrieval protocol in a Rydberg data register were shown via an impulsive half-cycle pulse and the more general problem of constructing a database-search algorithm. The sensitivity of the phase retrieval to the peak HCP field was explained by multimode interference. By programming the initial wave packet and the HCP, it was possible to create the correct interference conditions to produce any desired energy eigenstates.
