Geometric quantum control product

Geometry of quantum control for synchronisation: QFI / McLachlan metric / QNG catalogue, local metric spectrum diagnostics, and regularised natural- gradient direction probes. No experimental advantage claims at criticality.

Module: scpn_quantum_control.geometric_control_product

Rules

Rule Behaviour
Product schema geometric_control_product.v1
Ambient metric phase.variational_metric.mclachlan_metric
Ambient QNG phase.natural_gradient.solve_natural_gradient_direction with regularisation
Experimental advantage at criticality Refuse invent-green
Live QPU geometry Refused by the no-submit safety policy
Indefinite metric silent repair Refuse invent-green

Quick start

from scpn_quantum_control.geometric_control_product import (
    assert_geometric_control_product_integrity,
    build_geometric_control_product_registry,
    decide_geometry_path,
    materialise_demo_metric_diagnostics_probe,
    materialise_qng_direction_probe,
)

reg = assert_geometric_control_product_integrity(
    build_geometric_control_product_registry()
)
assert reg["experimental_advantage_criticality_policy"] is False

assert decide_geometry_path(
    "criticality_diagnostics", invent_green_advantage=True
).allowed is False

probe = materialise_demo_metric_diagnostics_probe()
assert probe.metric_rank + probe.metric_nullity == probe.n_parameters

qng = materialise_qng_direction_probe()
assert qng.regularization_reason

Residuals

  • Metric-spectrum dashboard panel depth
  • Notebook coverage and fuller claim-bounded narrative documentation
  • Ambient: phase.variational_metric, phase.natural_gradient, analysis.qfi
  • QNG regularisation · no-submit hardware safety · PGBO geometry composition
