An operating system for governed quantum infrastructure
SoftQuantus is an Estonian deep-tech company building QCOS — a vendor-neutral quantum infrastructure platform for orchestration and evidence. Today it runs CPU state-vector simulation (≤ 24 qubits) with an evidence bundle for every run.
Why SoftQuantus
Quantum workloads need governed operational infrastructure. We build it step by step and state only what we have measured.
A governed execution gap
Quantum backends differ in runtimes, and there is no common record of what ran and how. QCOS gives each run an evidence bundle sealed under a SHA-256 Merkle root and verifiable offline.
Measured, not promised
Today QCOS executes CPU state-vector simulation up to 24 qubits, with an evidence bundle per run. We withdrew our only optimiser benchmark (GHZ-6) in August 2026 when review found its setup favoured the optimiser. Everything beyond that is labelled as roadmap.
One control plane, not a single optimizer
QCOS combines orchestration, evidence bundles and benchmarking in one platform. QuantumLock adds licence enforcement with post-quantum licence tokens.
Proprietary core
The QCOS Autopilot architecture is proprietary; an invention disclosure is in process.
European positioning
Estonian legal entity with a EuroHPC AI Factory Large Scale allocation (EHPC-AIF-2025LS13-019) and Microsoft for Startups membership.
Validated Proof Points
Measured results, public packages and registered identifiers — not projections.
Programmes & funding pathways
EIC Funding Pathway
European Innovation Council (Horizon Europe) — a funding pathway we apply to
The European Innovation Council (Horizon Europe) is a funding pathway we apply to for QCOS development.
Extend QCOS as a governed, vendor-neutral orchestration platform, with every capability backed by an evidence record before it is claimed.
A funding pathway, not a partnership. No funding figures are published on this page.
