Quantum Operations
Execution and lifecycle management
QCOS is an operating system for quantum infrastructure. It runs circuits through one interface, records the execution mode, and seals an evidence bundle for every run under a SHA-256 Merkle root.
Enterprise quantum infrastructure software
SoftQuantus: quantum computing software for commercial quantum operations
SoftQuantus helps hardware vendors, HPC centers, and enterprise teams operate, secure, and scale quantum workloads from a single governed platform.
Our mission
One governed software layer between your teams and every quantum computer.
Quantum programs are moving from research into operational planning. What slows adoption is the absence of software that makes those programs governable, secure, and commercially viable.
About SoftQuantusWhy now
Why enterprise quantum stalls without quantum computing software
The ambition is there. What is missing is the operating layer: governance, integration and evidence that hold up outside the lab.
- 01
Quantum programs stall on operations, not on ambition
Most teams can design experiments. They still lose weeks to calibration windows, hardware drift, backend fragmentation, and workflows that break between runs.
- 02
Enterprise buyers need governance before they buy
Security, traceability, and post-quantum controls are mandatory when quantum touches regulated research, procurement, or production data. Most platforms provide none of them.
- 03
Every provider creates integration overhead
Every quantum provider and cloud exposes different runtimes and assumptions. Internal teams end up writing the same integration glue over and over.
- 04
Pilot results rarely become production evidence
Producing a result is straightforward. Proving it was reliable, reproducible, and acceptable for an internal decision or external audit is where most teams get stuck.
How it works
From a circuit to evidence, in four steps
The same path for every workload, whichever team sends it and whichever backend runs it.
01 · Submit
Send a circuit from your own tools
Teams submit work from the Python or TypeScript SDK, the softqcos CLI, or the REST API.
SDK · CLI · REST
02 · Govern
Apply identity, licence and plan controls
Each request carries its identity, a post-quantum licence token from QuantumLock, and the cost and plan controls set for the workspace.
QuantumLock · QSA
03 · Execute
Run it through one interface
QCOS runs the circuit through one interface and records the execution mode of every run.
CPU state-vector ≤ 24 qubits
04 · Prove
Seal the result as evidence
Every run produces an evidence bundle sealed under a SHA-256 Merkle root, ready for an internal decision or an audit.

The SoftQuantus platform
One quantum infrastructure software stack, three layers
QCOS governs quantum operations. QuantumLock and QSA secure access and identity. SynapseX and QCOS Bench close the developer and decision loop. Every product works standalone and compounds when combined.

Security
Post-quantum licensing and identity
QuantumLock provides post-quantum licence tokens and bring-your-own-key support for quantum workloads, alongside identity controls through Quantum-Safe Auth.
Development and decisions
AI for quantum development, and a view of where to run
SynapseX brings AI to quantum development. QCOS Bench helps teams decide where and when to run.

Use cases
Who buys enterprise quantum computing solutions
Four kinds of buyer, one platform. Each starts with the layer it needs and adds the rest as the program grows.
- Hardware vendors
Operate customer-facing quantum services with more control
Use QCOS to add orchestration, cost and plan controls, evidence, and reliability controls around your hardware, without locking customers into another provider-specific workflow.
- HPC centers
Offer governed quantum access alongside classical infrastructure
Add quantum resources to your service catalog with policy controls, reproducible benchmarks, and a clear commercial path from pilot access to contracted usage.
- Enterprise R&D teams
Run serious experiments without building your own quantum platform
Give internal teams a managed layer for execution, security, and evidence. They focus on research and use cases; we handle the infrastructure and provider integration.
- Regulated sectors
Bring governance to quantum before scale arrives
For finance, pharma, defence, and sovereign environments, SoftQuantus adds identity, tamper-evident evidence, and controlled execution to quantum programs before they reach operational scale.
From pilot to production
A developer workspace for quantum engineering teams
SynapseX and the developer toolchain shorten the path from experiment to repeatable delivery. Teams get SDKs, a command-line interface, and APIs, with CPU state-vector simulation (up to 24 qubits) available through QCOS.
- Python and TypeScript SDKs
- Command-line interface (softqcos CLI)
- CPU state-vector simulation (≤ 24 qubits) through QCOS
- REST APIs
- OpenTelemetry observability
