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)

Signed 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

Cryptographically signed bundles with hash chain. Any modification invalidates the signature.

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
