The operating system for quantum computers
Not software that runs on quantum. Software that keeps quantum running.
QCOS is the firmware layer between quantum hardware and your application — continuously self-calibrating, autonomously correcting hardware drift in real time, routing circuits using live hardware state, and sealing every execution with post-quantum cryptographic proof. Patent pending FR2513440.

Six subsystems that make QCOS a true operating system
Like a traditional OS has process scheduler, memory manager, and device drivers, QCOS provides the fundamental abstractions for quantum computing.
Autopilot — Closed-Loop Calibration
Patent pending FR2513440
Continuously monitors hardware state and applies corrections in real time — while circuits are executing, without stopping the system. Signed evidence proves every correction happened and fidelity improved. Other platforms require manual recalibration windows. This one does not. Patent pending FR2513440.
Decision Reliability Rating
Know before you execute
Before running any circuit, QCOS scores the reliability of the expected result. A proprietary multi-dimensional analysis determines whether your result will hold under real-world uncertainty — before you spend a single shot. Returns a 0–100 score and a GREEN / YELLOW / RED semaphore. No other platform does this.
Quantum Runtime
Unified execution environment
The core execution layer that manages quantum job lifecycle — from circuit submission to result retrieval. Handles queuing, scheduling, and resource allocation across all connected backends.
Hardware Abstraction Layer
Vendor-neutral drivers
Like device drivers in a traditional OS, the HAL provides a unified interface to all quantum hardware. IBM, IonQ, Azure Quantum, Amazon Braket — one API, any backend.
Quantum Scheduler
Intelligent job routing
The kernel scheduler decides which jobs run where and when. Cost-aware routing, priority queues, tenant isolation, and automatic backend matching based on circuit requirements.
Policy Engine
Governance-as-code
Define and enforce policies at the OS level. Budget limits, approval workflows, access controls, and compliance rules — checked before every execution, no exceptions.
Evidence Ledger
Cryptographic audit trail
Every execution produces a signed evidence bundle — circuit hash, timestamps, backend metadata, results, costs. Post-quantum signatures (ML-DSA) ensure tamper-proof records.
Deployment Modes
Cloud, on-prem, air-gapped
Like Linux runs anywhere, QCOS deploys in any environment. Cloud SaaS, VPC hybrid, or fully air-gapped sovereign installations with offline licensing and local chain of trust.
What QCOS is — and what it's not
QCOS is not a tool that manages quantum systems. QCOS is the system that quantum computers run on.
QCOS is
- Quantum operating system — unified runtime across all quantum hardware
- Hardware abstraction layer — vendor-neutral drivers for any QPU
- Quantum kernel — scheduler, policies, resource management
- Evidence system — cryptographically signed execution records
- Portable — cloud, on-prem, air-gapped, sovereign
QCOS is not
- A promise of quantum advantage — that depends on your algorithm
- A compiler or SDK replacement — use Qiskit, Cirq, PennyLane
- A proprietary runtime — we integrate, not replace
- A "magic optimizer" — gains are from control, not physics tricks
- Hardware-specific — provider-neutral by design
Verifiable metrics, not marketing claims
Every capability has a metric, a baseline, and a way to verify.
