Modular Entanglement — •Giulia Gualdi^1,2, Salvatore Marco Giampaolo², and Fabrizio Illuminati² — ¹Universiät Kassel Fachbereich 10 - Mathematik und Naturwissenschaften Institut für Physik Heinrich-Plett-Str. 40 D-34132 Kassel — ²Dipartimento di Matematica e Informatica, Università degli Studi di Salerno, Via Ponte don Melillo, I-84084 Fisciano (SA), Italy; CNR-SPIN, and INFN Sezione di Napoli, Gruppo collegato di Salerno, I-84084 Fisciano (SA), Italy

We introduce and discuss the concept of modular entanglement. This is the entanglement that is established between the end points of modular systems composed by sets of interacting moduli of arbitrarily fixed size. We show that end-to-end modular entanglement scales in the thermodynamic limit and rapidly saturates with the number of constituent moduli. We clarify the mechanisms underlying the onset of entanglement between distant and non-interacting quantum systems and its optimization for applications to quantum repeaters and entanglement distribution and sharing.
