Aquila, Our 256-qubit quantum Computer

QuEra's Aquila is currently the largest publicly-accessible machine in the world.
It is based on programmable arrays of neutral Rubidium atoms, trapped in vacuum by tightly focused laser beams.

Now accesible via Amazon Braket
Quera computer
Large and Powerful

Solve complex problems by mapping problems into the flexible programmable geometry of 256 neutral atoms.

Robust to Noise

Operating in the analog quantum processing mode, Aquila performs continuous temporal control over its qubits. This solves one of the key issues for today’s gate-based computers: the compounding of gate errors. Entanglement is generated and manipulated via direct design of Aquila’s natural atomic  Hamiltonian.

Flexible programmability

With customer-defined qubit layout and connectivity, Aquila enables unique strategies for algorithm development. Aquila is ready for the easy deployment of applications in quantum simulation, optimization, and machine learning.

Best Practices

Analog quantum programming is a powerful avenue for developing applications that can efficiently harness the power of large quantum systems. To maximize the benefits of this operational mode, we recommend:

Leverage parallel processing

With its 256 qubits and expansive field of view, Aquila offers a broad canvas for problem decomposition into replicas of compact clusters or extended chains, particularly for one-dimensional problems. Consider utilizing this capability to parallelize your computations, thereby improving the overall throughput.

Leverage the geometry

The flexibility to reconfigure qubit positions and manage their interconnections opens up a wide array of problem-solving possibilities that can be mapped onto Aquila's native Hamiltonian. Harness the power of this Field Programmable Qubit Array (FPQA™) feature to build diverse lattices, encode gauge constraints, and explore optimization via a multitude of graph mapping strategies.

Think analog, not digital

In analog computing mode, digital gates give way to smooth time evolutions. It's important to remember that various protocols, like quantum evolution via Trotterization, can gain advantages by sidestepping the errors that often accompany compounded gates.

Leverage the Rydberg blockade, but remember to account for interaction tails

The Rydberg blockade plays a pivotal role in numerous applications for Aquila, encompassing specific ordered phases and the computation of Maximum Independent Sets. While these applications are shaped by strong interactions, it's crucial to recognize the significance of the tails of longer-distance interactions. These tails facilitate longer-range frustration, stabilize spin liquids, and offer other possibilities.

Push the boundaries

Avoid relying exclusively on classical simulation for benchmarking. Aquila's capacity for quantum dynamical evolution extends beyond the limits of classical possibilities.
