Quantum-Safe Copyleft
for Observation Outputs

A copyleft license for research data, AI outputs, quantum & classical calculations — with mandatory post-quantum release integrity.

“The Apparatus does not own the Outcome.”

Q-Day in Spec QGPL v3.0 Author Dr. Šarūnas Grigaliūnas
Why QGPL

Harvest Now, Decrypt Later

Adversaries are already capturing encrypted scientific datasets, model outputs, and signed releases. When large-scale quantum computers arrive, RSA, ECDSA, and EdDSA fall — and so does the integrity of every artifact signed only with them. Open Results that outlive their cryptography are not open. They are forgeable.

1 · Harvest Now

State and well-resourced actors record encrypted traffic and signed bundles today — datasets, model weights, mirror tarballs, signatures — and store them indefinitely.

2 · Decrypt & Forge Later

Once cryptanalytically relevant quantum computers exist, RSA / ECDSA / EdDSA signatures over historical artifacts become forgeable. Provenance for a generation of open Results collapses retroactively.

What this means for open data & open AI

Open GPL and Creative Commons works ship with classical signatures (or none). The license language does not require post-quantum integrity. QGPL closes that gap by making Quantum-Safe Distribution Metadata a copyleft obligation — not an optional extra.

Compare

GPL vs QGPL

Both are copyleft. They protect different things, for different lifetimes.

GPL v3 / AGPL QGPL v3.0
Primary subject Source code Observation Outputs (Results), datasets, and Apparatus Code
Covers research data & AI outputs No (CC-style licenses needed) Yes — first-class
Database rights (sui generis) Partial / unclear Explicit grant
Copyleft / share-alike Yes Yes — “Entangled Freedom”
Anti-DRM / anti-tivoization Yes Yes — incl. crypto access locks
Post-quantum release signatures Not required Mandatory (Section 5.1)
PQ / hybrid key establishment for transport Not addressed Required when crypto is used (5.2)
Algorithm agility (NIST PQ revisions) N/A Built-in (5.3)
Patent grant and retaliation Yes Yes
Provenance integrity clause Implicit Explicit (Section 3.3)

QGPL is designed to complement, not replace, GPL. Code can stay under GPL while the Results it produces are released under QGPL.

Principles

Five Principles of QGPL

01

Superposition

Prior to observation, information exists in all states — unowned and boundless.

02

Universal Ownership

The Collapsed State of an observation belongs to the common reality of all Observers. No entity can copyright a fact derived from reality.

03

Independence from Apparatus

You may own the quantum computer, the GPU cluster, or the laboratory. You do not own the calculation it produces.

04

Entangled Freedom

If you use a QGPL Result to derive new Results, those remain QGPL. Reality cannot be enclosed.

05

Quantum Protection

Channels that carry a Result into the future must outlast the machines that would break them. Distribution integrity must be quantum-resistant.

Apply

Use QGPL in your work

Attach the notice to your dataset, model checkpoint, paper supplement, or repository. Ship Quantum-Safe Distribution Metadata alongside the artifact.

Tooling

QGPL Compliance Toolkit

A single CLI — qgpl — that signs, verifies, inspects, and audits artifacts under Section 5. Reference implementation plus a portable, re-implementable file format so the obligation is trivial to meet.

Sign

qgpl sign results.csv produces an ML-DSA-65 signature, manifest, and detached .sig. Hybrid PQ and classical optional.

Verify

qgpl verify with --pq-only mode for archival recovery and --strict-issuer for pinned roots.

Audit

qgpl audit release/ walks a directory and reports which artifacts lack compliant Section 5 metadata.

Academic & public sector

For institutional & European adoption

QGPL is positioned for Lithuanian and European scientific institutions releasing open datasets, AI outputs, and quantum computation results — and for the European Quantum Communication Infrastructure ecosystem where post-quantum release integrity is a baseline requirement, not a future upgrade.

Open data & QCI alignment

Drop-in copyleft for open research-data deposits at Lithuanian and EU institutions; alignment target for the QCI.lt initiative and broader European Quantum Communication Infrastructure programs.

Ecosystem

Legal-technical layer, alongside risk assessment

QGPL is the licensing layer. ResilQ (via RQmod.com) is the technical risk-assessment layer for post-quantum readiness. Together they cover the legal obligation, the cryptographic obligation, and the operational evidence for releasing Results in a quantum-vulnerable world.
