A Comprehensive Modeling Toolkit for Ion Trap Platforms: Application to Light Shift Gate

Abstract

Quantum operations in ion traps are commonly performed using laser beams, which can induce specific quantum gates by carefully controlling the laser pulses' intensity, phase, and duration. One powerful technique for implementing quantum gates in ion traps is the use of light shift gates [1, 2]. These gates are attractive because they are technically simple and natively insensitive to optical phases. We present here a comprehensive modeling toolkit for ion trap platforms, designed to simulate experimental conditions and optimize the control of light pulse shapes to maximize gate fidelity. We demonstrate the toolkit's application using light shift gates as a case study, showcasing its effectiveness in designing pulse sequences that account for noise sources and enhance gate performance. By optimizing control pulses, our approach allows researchers to design optimal pulse sequences for specific experimental setups, minimizing the impact of noise and enhancing gate performance.
