Science first. Always.
Quantum advantage is earned in the lab. Here's the road we've travelled — and what we're publishing along the way.
- 2021
Brangus founded
A team of physicists and systems engineers set out to make fault tolerance practical, not just theoretical.
- 2022
First multi-qubit lattice
Demonstrated a 16-qubit superconducting processor with record two-qubit gate fidelity for its class.
- 2023
Below threshold
Showed surface-code error rates dropping as we added qubits — the key signature of a scalable architecture.
- 2024
Quantum Cloud beta
Opened the Brangus SDK to research partners, running hybrid workloads on live hardware.
- 2025
QPU-3 & logical qubits
Launched our modular QPU-3 with real-time decoding, operating the first generation of logical qubits in production.
