Amplitude and phase-controlled beam arrays for trapped-ion simulation using a spatial light modulator
ORAL
Abstract
Individual addressing of trapped ions and atoms enables the simulation of complex many-body spin-spin models and quantum computation. Spatial light modulators provide the flexibility to generate arbitrary light patterns that can be matched to the spacing of ions in a crystal. We report on the generation of beam arrays with independent phase and amplitude control using a single phase-only SLM. Such control allows for coherent manipulation of individually addressed ions.
We discuss both a generalized feedback-based weighted Gerchberg-Saxton (GSW) algorithm [1] and a gradient-descent method [2] for generating beam arrays that can address and couple to ion motion in 1D and 2D ion crystals. We also discuss a proposed implementation of such beam arrays for a light shift gate via the 2S1/2-2D5/2 quadrupole transition [3,4] in a 171Yb+ ion chain, using an array of TEM01 beams to couple to the axial modes of motion [5].
