We're excited to share that Rigetti's Cepheus™-1-108Q, the largest modular quantum system in the industry, is now available to qBraid Lab users via direct integration. This is one of the biggest jumps in accessible qubit count we've ever shipped to the qBraid community, and it's live today!
Cepheus-1-108Q triples the qubit and chiplet count of Rigetti's previous Cepheus-1-36Q system by interconnecting twelve 9-qubit chiplets into a single 108-qubit processor. It's a real validation of Rigetti's proprietary modular chiplet architecture and a meaningful step on the road to fault tolerance.
The system has achieved the following performance:
Rigetti has indicated they'll continue tuning fidelity and performance throughout 2026, so expect this device to keep getting better.
108 qubits opens the door to circuit depths and problem sizes that were impractical on smaller devices. A few of the workloads our community has been waiting for this kind of headroom on:
Because this is a direct integration, you can submit jobs to Cepheus-1-108Q from inside qBraid Lab using the same qbraid SDK workflow you already know. No new accounts, no separate cloud setup. Open a notebook, pick the device, run the circuit.
With this new capability coming online, Rigetti's Ankaa™-3 is being retired from qBraid Lab. Ankaa-3 has been one of the most popular devices on the platform since we brought it online, powering everything from undergraduate course assignments and hackathon projects to serious research workloads across our 27,000+ developer community. It set a high bar for what an accessible superconducting device should feel like to use.
If you have active projects on Ankaa-3, here's what you need to know:
A genuine thank you to everyone who ran experiments on Ankaa-3. The data, papers, and student projects that came out of it are exactly why we keep pushing to bring more hardware to the community.
Cepheus-1-108Q is available now on qBraid Lab. To run your first circuit:
The qBraid transpiler handles cross framework conversions, so you can write in whatever SDK your team prefers and target Cepheus-1-108Q without rewriting a thing.
qBraid is open source, and we love seeing what the community builds. If you're working on a project that takes advantage of larger qubit systems like Cepheus-1-108Q, star us, file an issue, or open a PR: github.com/qBraid/qBraid. We're especially keen to see error correction prototypes, chiplet aware compilation tricks, and benchmarking results from the new device.
