Critical spin models from holographic disorder
Dimitris Saraidaris, Alexander Jahn
Discrete models of holographic dualities, typically modeled by tensor networks on hyperbolic tilings, produce quantum states with a characteristic quasiperiodic disorder not presen…
Holographic Codes from Hyperinvariant Tensor Networks
Matthew Steinberg, Sebastian Feld, Alexander Jahn
Holographic quantum-error correcting codes are models of bulk/boundary dualities such as the anti-de Sitter/conformal field theory (AdS/CFT) correspondence, where a higher-dimensio…
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…
Boundary theories of critical matchgate tensor networks
Alexander Jahn, Marek Gluza, Charlotte Verhoeven +2
Key aspects of the AdS/CFT correspondence can be captured in terms of tensor network models on hyperbolic lattices. For tensors fulfilling the matchgate constraint, these have prev…
Holographic tensor network models and quantum error correction: A topical review
Alexander Jahn, Jens Eisert
Recent progress in studies of holographic dualities, originally motivated by insights from string theory, has led to a confluence with concepts and techniques from quantum informat…
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…
