How It Works

Run → Bundle → Store → Sign → Verify

Complete evidence lifecycle in 60 seconds. Every step cryptographically linked.

1

Run

Execute standardized benchmark workloads on any quantum backend

Raw execution telemetry
2

Bundle

Package results, metadata, and provenance into evidence bundle

Evidence bundle (.tar.gz)
3

Store

Persist to durable object storage (Azure Blob / AWS S3)

Immutable blob + Postgres metadata
4

Sign

Cryptographic signature with Ed25519 (ML-DSA post-quantum ready)

Sealed evidence with hash chain
5

Verify

Third-party verification — online or air-gapped

Verification report + attestation
terminal
# Verify evidence bundle locally (offline)
$ qcos bench verify ./evidence_bundle_2026-01-09.tar.gz

✓ Signature valid (Ed25519)
✓ Hash chain intact (SHA-256)
✓ Provenance verified
✓ No tampering detected

Why Procurement Cares

Built for Enterprise Audit

Not vendor marketing — verifiable evidence for hardware acquisition decisions.

Tamper-Evident Evidence

Sealed evidence bundles with a hash chain. Any modification breaks the chain and invalidates the seal.

Chain of Custody

Full audit trail from execution to storage. Every state transition logged and timestamped.

Durable Storage

Enterprise-grade blob storage (Azure/S3) with configurable retention. Metadata in PostgreSQL for queryability.

Offline Verification

Verify evidence bundles without network access. Perfect for air-gapped sovereign environments.

Reproducible Results

Same workloads, any backend, comparable outputs. Standardized benchmark suite versioned and documented.

Post-Quantum Ready

Ed25519 today, ML-DSA migration path. Future-proof cryptographic signatures.

Deployment Options

Your Data, Your Rules

SaaS

Fully managed service. Evidence stored in SoftQuantus infrastructure.

  • Zero infrastructure
  • Automatic updates
  • Global availability
Ideal for: R&D teams, fast evaluation

VPC / Private Cloud

Deploy in your cloud account. Data never leaves your perimeter.

  • Your storage accounts
  • Your key management
  • Your retention policies
Ideal for: Enterprise with cloud compliance

Sovereign / Air-gapped

Fully offline deployment. No internet connectivity required.

  • BYOK (HSM/KMS)
  • Offline verification
  • Export controls compliant
Ideal for: Government, defense, regulated industries
