What makes our trapped-ion systems so transformative

1

Proven to scale through QCCD architecture:  

‍A quantum charge-coupled device (QCCD) architecture enables a clear path to scaling while maintaining extremely high fidelity operations.

‍

2

Real-time error correction  enabled by mid-circuit measurement:

Measure select qubits in real-time and condition future quantum operations all while inadvertently measuring other qubits. This capability is crucial to creating fault-tolerant quantum computers and enabled the first ever demonstration of real-time quantum error correction.

Greater control, stronger results:  

Moving and regrouping qubits into arbitrary pairs, which we call all-to-all connectivity, with near-perfect fidelity enables users to have maximum flexibility in algorithm design. This enables resource reduction in the computational steps required to executing quantum algorithms, thereby providing higher-fidelity results.

Realizing the world-changing power of quantum computing will require many qubits, high physical fidelity, and fault tolerance. Our systems have unparalleled fidelity, combined with all-to-all connectivity, mid-circuit measurement, and qubit reuse, giving us an unmatched advantage for pushing the field of quantum computing forward. And the results speak for themselves.
