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…
Holographic properties of superposed quantum geometries
Eugenia Colafranceschi, Simon Langenscheidt, Daniele Oriti
We study the holographic properties of a class of quantum geometry states characterized by a superposition of discrete geometric data, in the form of generalised tensor networks. T…
Holographic entanglement in spin network states: a focused review
Eugenia Colafranceschi, Gerardo Adesso
In the long-standing quest to reconcile gravity with quantum mechanics, profound connections have been unveiled between concepts traditionally pertaining to quantum information the…
Bulk area law for boundary entanglement in spin network states: entropy corrections and horizon-like regions from volume correlations
Goffredo Chirco, Eugenia Colafranceschi, Daniele Oriti
For quantum gravity states associated to open spin network graphs, we study how the entanglement entropy of the boundary degrees of freedom (spins on open edges) is affected by the…
Holographic maps from quantum gravity states as tensor networks
Eugenia Colafranceschi, Goffredo Chirco, Daniele Oriti
We define bulk/boundary maps corresponding to quantum gravity states in the tensorial group field theory formalism, for quantum geometric models sharing the same type of quantum st…
Quantum gravity states, entanglement graphs and second-quantized tensor networks
Eugenia Colafranceschi, Daniele Oriti
In recent years, the import of quantum information techniques in quantum gravity opened new perspectives in the study of the microscopic structure of spacetime. We contribute to su…
Refined diamond norm bounds on the emergence of objectivity of observables
Eugenia Colafranceschi, Ludovico Lami, Gerardo Adesso +1
The theory of Quantum Darwinism aims to explain how our objective classical reality arises from the quantum world, by analysing the distribution of information about a quantum syst…
