HIDDEN ENTANGLEMENT AND UNITARITY AT THE PLANCK SCALE
HIDDEN ENTANGLEMENT AND UNITARITY AT THE PLANCK SCALE
We discuss how relaxing the requirement of locality for quantum fields can equip the Hilbert space of the theory with a richer structure in its multi-particle sector. A physical consequence is the emergence of a "planckian" mode-entanglement, invisible to an observer that cannot probe the Planck scale. To the same …
