Abstract

fetched live from OpenAlex

We prove conjectures on the relative entropy of entanglement (REE) for two families of multipartite qubit states. Thus, analytical expressions of the REE for these families of states can be given. The first family of states is composed of mixtures of some permutation-invariant multiqubit states. The results generalized to multiqudit states are also shown to hold. The second family of states contains D\"ur's bound entangled states. Along the way, we discuss the relation of the REE to two other measures: robustness of entanglement and the geometric measure of entanglement, slightly extending previous results.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
