The Structure of the Continuum Limit of Spin Foams
Matteo Bruno, Eugenia Colafranceschi, Fabio M. Mele +1
The Spin Foam approach to quantum gravity aims at providing a covariant path-integral formulation of canonical Loop Quantum Gravity. Since spin foam amplitudes are defined through…

Holographic Codes from Enriched Link Entanglement in Spin Networks
Mai Qi, Eugenia Colafranceschi
We introduce an enriched entanglement structure for spin networks, inspired by tensor-network constructions, in which internal links can carry a controlled and discrete amount of e…

Channel-State duality with centers
Simon Langenscheidt, Eugenia Colafranceschi, Daniele Oriti
We study extensions of the mappings arising in usual channel-state duality to the case of Hilbert spaces with a direct sum structure. This setting arises in representations of alge…
