Verify before execution
Validate manifest, circuit structure, policy gates, target, and authorized workload identity.
Public alpha live
Trust infrastructure for high-stakes quantum execution.
QuantumD binds verification, authorization, execution, and results into a cryptographically verifiable evidence chain. The source is now public, the alpha is installable, and every claim can be inspected.

The control point
AI may propose. QuantumD decides what is permitted to run.
A successful cloud job and a complete log trail do not prove that the approved workload was the workload actually executed. Plans can be replayed, job identifiers substituted, and results altered while each individual system still appears valid.
QuantumD closes that gap by binding reviewer intent, workload identity, policy decisions, provider submission, execution receipts, and result artifacts into one inspectable chain.
Bind approval to intent
Prevent authorization replay and make reviewer intent part of the signed execution record.
Reconcile after execution
Connect provider job identity, observed shots, results, and receipts back to the approved plan.
The Evidence Graph
Every decision becomes part of the proof.
QuantumD treats the execution lifecycle as a graph of signed, hashed, and mutually bound evidence rather than a collection of unrelated logs.
Verification
What was reviewed, validated, and permitted.
Authorization
Who approved the exact verified workload.
Execution
What target ran, when, and under which constraints.
Result
Which artifact and observed shots were produced.
Proof
An independently verifiable chain of custody.
Public alpha boundary
Local development is intentionally constrained.
- Trust mode
- LOCAL_DEVELOPMENT
- Trust scope
- LOCAL_SIMULATION_ONLY
- Hardware authorization
- PROHIBITED
- IBM contacted
- False
- KMS contacted
- False
Why this matters
A local signature is not silently promoted into production authority.
The alpha demonstrates the complete evidence architecture while preserving a hard boundary between educational simulation and governed hardware execution.
Read the alpha boundariesLaunch proof
Public by evidence, not announcement alone.
The August 2, 2026 public launch was completed only after a zero-finding, zero-warning audit and anonymous installation verification.
Protected development
Pull requests, governed CI, linear history, and thread resolution protect main.
Protected secrets
Secret scanning, push protection, and private vulnerability reporting are enabled.
Protected release identity
Repository-bound Workload Identity Federation signs through a least-privilege KMS identity.
Start with QuantumD
Install in one command. Verify every execution.
Install QuantumD directly from production PyPI. The local quickstart creates a simulator-only governed project, executes an evidence-bound workload, and independently verifies the resulting evidence chain.

$ pip install quantumd
$ quantumd quickstart my-project
$ quantumd verify-chain my-project --latest
