Engineering quantum states with neutral atoms
arxiv(2024)
摘要
Aquila, an analog quantum simulation platform developed by QuEra Computing,
supports control of the position and coherent evolution of up to 256 neutral
atoms. This study details novel experimental protocols designed for analog
quantum simulators that generate Bell state entanglement far away from the
blockade regime, construct a Z2 state with a defect induced by an ancilla, and
optimize the driving fields schedule to prepare excited states with enhanced
fidelity.
We additionally evaluate the effectiveness of readout error mitigation
techniques in improving the fidelity of measurement results. All experiments
were executed on Aquila from QuEra and facilitated by the AWS Braket interface.
Our experimental results closely align with theoretical predictions and
numerical simulations. The insights gained from this study showcase Aquila's
capabilities in handling complex quantum simulations and computations, and also
pave the way for new avenues of research in quantum information processing and
physics that employ programmable analog hardware platforms.
