Overlapping qubits from non-isometric maps and de Sitter tensor networks
ChunJun Cao, Wissam Chemissany, Alexander Jahn +1
We construct approximately local observables, or "overlapping qubits", using non-isometric maps and show that processes in local effective theories can be spoofed with a quantum sy…
Long-distance entanglement of purification and reflected entropy in conformal field theory
Hugo A. Camargo, Lucas Hackl, Michal P. Heller +2
Quantifying entanglement properties of mixed states in quantum field theory via entanglement of purification and reflected entropy is a new and challenging subject. In this work, w…
Entanglement and Complexity of Purification in (1+1)-dimensional free Conformal Field Theories
Hugo A. Camargo, Lucas Hackl, Michal P. Heller +3
Finding pure states in an enlarged Hilbert space that encode the mixed state of a quantum field theory as a partial trace is necessarily a challenging task. Nevertheless, such puri…
Central charges of aperiodic holographic tensor network models
Alexander Jahn, Zoltán Zimborás, Jens Eisert
Central to the AdS/CFT correspondence is a precise relationship between the curvature of an anti-de Sitter (AdS) spacetime and the central charge of the dual conformal field theory…
Majorana dimers and holographic quantum error-correcting codes
Alexander Jahn, Marek Gluza, Fernando Pastawski +1
Holographic quantum error-correcting codes have been proposed as toy models that describe key aspects of the AdS/CFT correspondence. In this work, we introduce a versatile framewor…
Entanglement of Purification in Many Body Systems and Symmetry Breaking
Arpan Bhattacharyya, Alexander Jahn, Tadashi Takayanagi +1
We study the entanglement of purification (EoP), a measure of total correlation between two subsystems and , for free scalar field theory on a lattice and the transverse-fie…
