A nonabelian anyon violates Haag duality
Daniel Wallick, Henrik Wilming
We show that a superselction sector describing a single nonabelian anyon violates Haag duality, which is equivalent to the fundamental quantum-information theoretic principle of un…
Quantum steering is equivalent to state-preserving conditional expectations
Lauritz van Luijk, Amine Marrakchi, Tobias Osborne +2
In systems with infinitely many degrees of freedom, fundamental results from quantum information theory can fail. An important example is the uniqueness of purifications: Even when…
Uniqueness of purifications is equivalent to Haag duality
Lauritz van Luijk, Alexander Stottmeister, Henrik Wilming
The uniqueness of purifications of quantum states on a system up to local unitary transformations on a purifying system is central to quantum information theory. We show th…
Revisiting the operator extension of strong subadditivity
Lauritz van Luijk, Alexander Stottmeister, Henrik Wilming
We give a new proof of the operator extension of the strong subadditivity of von Neumann entropy by identifying the mathe…
Gaussian fermionic embezzlement of entanglement
Alessia Kera, Lauritz van Luijk, Alexander Stottmeister +1
Embezzlement of entanglement allows to extract arbitrary entangled states from a suitable embezzling state using only local operations while perturbing the resource state arbitrari…
The Large-Scale Structure of Entanglement in Quantum Many-body Systems
Lauritz van Luijk, Alexander Stottmeister, Henrik Wilming
We show that the thermodynamic limit of a many-body system can reveal entanglement properties that are hard to detect in finite-size systems -- similar to how phase transitions onl…
Pure state entanglement and von Neumann algebras
Lauritz van Luijk, Alexander Stottmeister, Reinhard F. Werner +1
We develop the theory of local operations and classical communication (LOCC) for bipartite quantum systems represented by commuting von Neumann algebras. Our central result is the…
Multipartite Embezzlement of Entanglement
Lauritz van Luijk, Alexander Stottmeister, Henrik Wilming
Embezzlement of entanglement refers to the task of extracting entanglement from an entanglement resource via local operations and without communication while perturbing the resourc…
Critical Fermions are Universal Embezzlers
Lauritz van Luijk, Alexander Stottmeister, Henrik Wilming
Universal embezzlers are bipartite quantum systems from which any entangled state may be extracted to arbitrary precision using local operations while perturbing the state of the s…
Embezzlement of entanglement, quantum fields, and the classification of von Neumann algebras
Lauritz van Luijk, Alexander Stottmeister, Reinhard F. Werner +1
We study the quantum information theoretic task of embezzlement of entanglement in the setting of von Neumann algebras. Given a shared entangled resource state, this task asks to p…
Relativistic Quantum Fields Are Universal Entanglement Embezzlers
Lauritz van Luijk, Alexander Stottmeister, Reinhard F. Werner +1
Embezzlement of entanglement refers to the counterintuitive possibility of extracting entangled quantum states from a reference state of an auxiliary system (the "embezzler") via l…
Sufficiency of Rényi divergences
Niklas Galke, Lauritz van Luijk, Henrik Wilming
A set of classical or quantum states is equivalent to another one if there exists a pair of classical or quantum channels mapping either set to the other one. For dichotomies (pair…
Covariant catalysis requires correlations and good quantum reference frames degrade little
Lauritz van Luijk, Reinhard F. Werner, Henrik Wilming
Catalysts are quantum systems that open up dynamical pathways between quantum states which are otherwise inaccessible under a given set of operational restrictions while, at the sa…
Reviving product states in the disordered Heisenberg chain
Henrik Wilming, Tobias J. Osborne, Kevin S. C. Decker +1
When a generic quantum system is prepared in a simple initial condition, it typically equilibrates toward a state that can be described by a thermal ensemble. A known exception are…
Revisiting the equality conditions of the data processing inequality for the sandwiched Rényi divergence
Jinzhao Wang, Henrik Wilming
We provide a transparent, simple and unified treatment of recent results on the equality conditions for the data processing inequality (DPI) of the sandwiched quantum Rényi diverge…
Work and entropy production in generalised Gibbs ensembles
M. Perarnau-Llobet, A. Riera, R. Gallego +2
Recent years have seen an enormously revived interest in the study of thermodynamic notions in the quantum regime. This applies both to the study of notions of work extraction in t…
