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…
