Local quickstart

quantumd quickstart creates and executes a complete locally governed simulator workflow.

Install the published alpha first by following the installation guide.

Run it

quantumd quickstart ./quantumd-first-run --shots 128

QuantumD will:

  1. initialize a project
  2. create a project-local P-256 signing identity
  3. evaluate verification and policy gates
  4. authorize only aer-simulator
  5. execute the verified workload
  6. sign the verification evidence and execution receipt
  7. verify the resulting chain offline

A successful run ends with:

[STATUS] QUANTUMD LOCAL QUICKSTART COMPLETE
Trust mode:             LOCAL_DEVELOPMENT
Trust scope:            LOCAL_SIMULATION_ONLY
Hardware authorization: PROHIBITED
KMS signing used:       False
IBM contacted:          False
Hardware action:        None

Inspect the trust posture

quantumd doctor ./quantumd-first-run

The expected local posture is:

Active trust mode:      LOCAL_DEVELOPMENT
KMS key configured:     False
Local identity valid:   True
Local trust scope:      LOCAL_SIMULATION_ONLY
Hardware authorization: PROHIBITED

Verify the chain

quantumd verify-chain ./quantumd-first-run --latest

The verifier checks signatures, key lineage, authorization, source and manifest identities, workload binding, circuit identities, the result hash, shot count, and execution timing.

The verifier performs no IBM or KMS calls for a local chain.

Local identity

The private identity is project-local and excluded from Git. QuantumD stores it beneath:

.quantumd/local-trust/

Partial, corrupted, or mismatched identity state is rejected rather than silently repaired. A local identity cannot authorize IBM hardware.
