IonQ Aria

Available Since 2022

The world's best publicly-disclosed, commercially available quantum computer. Available on the IonQ Quantum Cloud and select public clouds.

Visualization: Aria’s all-to-all connectivity graphIonQ QPUs are fully connected. The 25 points on the perimeter of the image represent Aria’s 25 qubits. The lines represent the 300 potential entangling gates that can be run across those qubits.

Tackle Larger Problem Sizes

With a demonstrated #AQ of 25 (commercially available #AQ of 23), a higher qubit count, and our best gate fidelities, IonQ Aria enables bigger, more complex problems to be explored.

Get Results with Fewer Iterations

IonQ Aria’s higher #AQ of 25 (commercially available #AQ of 23) means less noise in the quantum system. With less noise, even the most complex problems take fewer iterations, saving valuable time and money.

  • Highest Gate Fidelity

    Highest Gate Fidelity

    Ion qubits have achieved the lowest gate error rate of any quantum technology. 

  • All To All Connectivity

    All-To-All Connectivity

    Any qubit in the system can be directly entangled with any other qubit. 

  • Fully Software Configurable

    Fully Software Configurable

    IonQ’s trapped ion architecture can be configured to meet various computational demands. 

  • Longest Coherence Times

    Longest Coherence Times

    Ion qubits have achieved the longest coherence times of any quantum technology. 

  • Clear Path To Error Correction

    Clear Path to Error Correction

    We believe trapped ions will require fewer total qubits for error correction compared to other quantum.

Aria Is the World's Most Useful Quantum Computer

Demonstrated #AQ 25

With Configurable Error Mitigation
(commercially available #AQ 23)

#AQ measures the usefulness of a quantum computer. For example, with Aria’s configurable error mitigation, #AQ 25 would mean you could successfully run quantum algorithms of ~600 entangling gates on up to 25 qubits.

  • 25

    Demonstrated #AQ With Configurable Error Mitigation
    (Commercially available #AQ 23) Algorithmic Qubits (#AQ) is a summary metric that counts the number of algorithmically “useful” qubits in a quantum system. Aria defaults to running jobs with error mitigation, which drives a higher #AQ. However, customers have the option to turn off error mitigation, if desired.

  • 25

    Qubit Count at Demonstrated #AQ 25
    (23 qubits at commercially available #AQ 23) The number of physical qubits in the system. If everything else were perfect, qubit count would equal #AQ. It’s not, which is why we need other metrics!

  • 0.06%

    1-Qubit Gate Error The average error introduced during a single single-qubit gate. Aria’s 1Q gate error is about six parts in ten thousand (0.06%).

  • 0.6%

    2-Qubit Gate Error The average error introduced during a single two-qubit gate. Aria’s 2Q gate error is about sixty parts in ten thousand (0.6%).

  • 0.39%

    SPAM Error The average error introduced during state preparation and measurement. Aria’s SPAM error is about thirty-nine parts in ten thousand (0.39%), and our new Barium system can do about four in ten thousand. More on SPAM and Barium

  • 10–100s, ~1s

    T1 & T2 Time Two factors of the amount of time a qubit “stays a qubit,” T1 measures how long you can tell what’s a one vs a zero, and T2 measures phase coherence.

IonQ and GE Research Demonstrated High Potential of Quantum Computing for Risk Aggregation

Key Results:

  • Trained financial risk model with 3 and 4 variables - based on historical stock indexes which exponentially increases problem size area that can be run on Aria

  • Created an innovative form of optimization called annealing training

  • In some cases our quantum predictions outperformed classical modeling approaches

GE Research Logo

“The early results we achieved in the financial use case with IonQ shows the high potential of quantum computing to better understand and reduce the risks associated with these types of highly variable scenarios.”
