Entanglement map · Refuted

Entanglement is reversible under all non-entangling operations

The statement shown is false.

Lami and Regula showed this is false: entanglement theory is irreversible under all non-entangling transformations, so reversibility would need a macroscopic amount of entanglement generated along the way, by certain measures.
