Engineering quantum states with neutral atoms

Understand

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 $Z_2$ 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.
