Open-system MCWF completeness product

August 26, 2026 · View on GitHub

Documented, fail-closed open-system dynamics completeness: Lindblad and MCWF surfaces, seeded ensemble variance certificates, simulation noise-model I/O, and hard gaps for non-CP / non-Markovian / adjoint / hardware noise.

Quick start

from scpn_quantum_control.open_system_mcwf_product import (
    assert_open_system_mcwf_product_integrity,
    build_open_system_mcwf_product_registry,
    decide_open_system_path,
    materialise_demo_mcwf_ensemble_probe,
    materialise_reproducibility_probe,
)

reg = assert_open_system_mcwf_product_integrity(
    build_open_system_mcwf_product_registry()
)
assert reg["hardware_noise_fidelity_claim_policy"] is False

assert decide_open_system_path(
    "mcwf_ensemble", invent_green_hardware_noise=True
).allowed is False

probe = materialise_demo_mcwf_ensemble_probe()
assert probe.invent_green_hardware_noise is False

repro = materialise_reproducibility_probe()
assert repro.certificate["passed"] is True

Residuals (honest)

  • Fuller committed evidence breadth beyond the current objective suite
  • Comparative closed, open, and hardware-noisy gradient documentation
  • Ambient: scpn_quantum_control.phase.tensor_jump, open_system_objectives
  • Bounded open-system objectives · no-submit hardware-safety policy
