Qbron logo — a Norse-inspired bridge mark

Qbron.

The quantum bridge.

In Swedish, bron means bridge. Qbron is the Quantum bron — an open-source SDK and Nordic-resident managed cloud that lets you write a quantum circuit once and route it to whichever QPU is cheapest, fastest, or most accurate today. IBM, IQM, AWS Braket, Azure, Pasqal, your laptop.

01

One API, every backend

Write your circuit once. Route it to the cheapest, fastest, or most accurate QPU available — automatically.

02

Open-source by default

Apache-2.0. Self-host it, audit it, fork it. Carve your own runes. The managed cloud is the easy button — never the lock-in.

03

Sovereign by design

EU-resident data plane. GDPR-native. Built for European research and regulated enterprise from commit 0.
