Figure X — Integrated Empirical Validation of the Collapse Criterion and Geometric Inference Failure

Craig Kyrle Strachan Davidson

This dataset presents the full empirical realisation of the Forensic Inversion Protocol (RE-INVERT), validating the Collapse Criterion governing inference failure in multi-witness systems. The figure integrates six panels (A–F), each corresponding to a structural component of the underlying geometric inference framework.Panel A demonstrates accurate recovery of interaction amplitudes under adjoint reconstruction, confirming numerical stability even near collapse. Panel B quantifies the competition between geometric stability, via the minimum eigenvalue of the Fisher Information Metric λ_min(t), and cumulative environmental distortion D(t). Panel C tracks the evolution of the dimensionless collapse parameter Γ(t), showing smooth convergence toward the critical threshold. Panel D empirically confirms loss of identifiability as Γ → 1, with reconstructed states exhibiting extreme dispersion. Panel E analyses the role of regularisation ε, demonstrating that bias–variance trade-offs cannot compensate for geometric degeneration. Panel F provides regime classification across rigid, stable, transitional, and collapsed phases.The results establish that inference failure arises from geometric degeneration of the Fisher metric, rather than numerical instability or noise amplification. The collapse parameter Γ(t) emerges as a universal control variable governing the transition from identifiable to non-identifiable regimes.This dataset supports and extends the theoretical results presented in:Trace Forensics — Paper 31: Fisher-Geometric Inference under Cascade RefinementTrace Forensics — Paper 2: Quantum Forensics via Environmental Bow WavesTrace Forensics — Paper 5: Multi-Witness Inference Foundations

Plenary Panel 4 - Quantum Software & Services

Quantum computing is a new and emergent computation parading, and we need to understand how it is going to be used and impact in the current software and services.Furthermore, it is necessary explore how connect quantum and conventional computation to take advantage in both sides.Understanding that one of the key components of this technology is the quantum hardware (Quantum Processing Units or QPUs), the software and algorithm need to cover from the core hardware to the final user.This software stack from one side need to help to new quantum developers to have better tools to handle and improve the quantum hardware, also create new algorithms and models, and finally how we are going to integrate all these pieces with the current conventional applications.In this journey we are going to need to discover use the powerful of this quantum computation and how the users can connect and develop new kind of software and services around of it.This panel is going to help to understand the current state of the art in the Quantum field, from the software near to the quantum hardware to services integrated on the cloud.The panel is moderated by Frank Leymann and Ismael Faro.
