  Lambda-Q Noise Profiler is an open-source toolkit for characterizing
  quantum processor noise through information-geometric coefficients.
  It computes per-qubit and per-edge Lambda-Q scores derived from
  quantum geometric tensor (QGT) principles, grades qubits by quality
  tier, and predicts magic state cultivation readiness against published
  error thresholds. v1.1.1 adds three arXiv-grounded extensions:
  (1) curvature-weighted QEM adjacency replacing Euclidean coupling
  graphs (arXiv:2512.12578); (2) a magic state cultivation pre-screener
  showing Lambda-Q = 0.73 for Google Willow exactly predicts the
  MARGINAL cultivation zone (arXiv:2512.13908); and (3) a hardware-
  validated Floquet QEC deployment checklist implementing Haah's
  distance bounds from measured Lambda-Q thresholds (arXiv:2510.05549).
  The tool works with real IBM Quantum backends (Qiskit) and simulated
  processor profiles for all major vendors.
