Quantum infrastructure software, built in Europe
SoftQuantus is an Estonian deep-tech company. We build QCOS — the operating system for governed quantum infrastructure — together with the security, evidence, and reliability layers that enterprises and research institutions need to run quantum hardware in production.
We make quantum hardware governable
Quantum hardware is becoming commercially accessible — but it is still difficult to operate in production. Hardware drifts, results are hard to verify, providers are fragmented, and there is no standard layer for governance or compliance.
SoftQuantus solves this with a software control layer that sits above the hardware: QCOS for calibration and operations, QuantumLock and QSA for security and access, SynapseX for AI-assisted development, and QCOS Bench for reproducible verification. Our customers are enterprises, national labs, HPC centers, and hardware vendors who need production-grade governance over quantum infrastructure.
Our principles
These core values guide everything we build.
Reproducibility First
Every quantum circuit execution should be reproducible across any hardware provider.
Provider Agnostic
No vendor lock-in. Work with IBM, Google, IonQ, Amazon Braket, or any other provider.
Audit Ready
Complete traceability and compliance for regulated industries.
Open Standards
Built on OpenQASM, MLIR, and open formats. No proprietary lock-in.
