Phase and Amplitude Control of light patterns for Trapped-Ion Quantum Simulation
POSTER
Abstract
Trapped ions provide a natural platform for the quantum simulation of spin and spin-boson models with a high degree of control and long coherence times achieved via tailored laser fields. Here we describe an optical setup wherein a phase-only spatial light modulator is used to shape a single incident Gaussian beam into an array of Hermite-Gaussian beams with arbitrary phase and intensity control [1]. The transverse electric field gradient of the Hermite-Gaussian beams will allow for coupling to axial modes of motion using a beam array that is orthogonal to the trap axis [2]. This will be achieved with geometric phase gates that have been shown to have high fidelities [3] and can be used to simulate spin-spin interactions between ions [4]. The beam array will address the quadrupole transition 2S1/2-2D3/2 to implement zz spin-spin interactions on the hyperfine qubit of 171Yb+ ions [5]. We present computational and experimental results of the optical scheme and optimization algorithm, including the characterization of the resulting beams' phase and intensity transverse profiles using an interferometer.
