  The neutral-atom quantum computer "Aquila" is QuEra's latest device available
through the Braket cloud service on Amazon Web Services (AWS). Aquila is a
"field-programmable qubit array" (FPQA) operated as an analog Hamiltonian
simulator on a user-configurable architecture, executing programmable coherent
quantum dynamics on up to 256 neutral-atom qubits. This whitepaper serves as an
overview of Aquila and its capabilities: how it works under the hood, key
performance benchmarks, and examples that demonstrate some quintessential
applications. This includes an overview of neutral-atom quantum computing, as
well as five examples of increasing complexity from single-qubit dynamics to
combinatorial optimization, implemented on Aquila. This whitepaper is intended
for readers who are interested in learning more about neutral-atom quantum
computing, as a guide for those who are ready to start using Aquila, and as a
reference point for its performance as an analog quantum computer.
