Stability of the bulk gap for frustration-free topologically ordered quantum lattice systems

B Nachtergaele, R Sims, A Young - Letters in Mathematical Physics, 2024 - Springer
We prove that uniformly small short-range perturbations do not close the bulk gap above the
ground state of frustration-free quantum spin systems that satisfy a standard local topological …

Critical Fermions are Universal Embezzlers

L van Luijk, A Stottmeister, H Wilming - arXiv preprint arXiv:2406.11747, 2024 - arxiv.org
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 …

L van Luijk, A Stottmeister, H Wilming - arXiv preprint arXiv:2409.07646, 2024 - arxiv.org
Embezzlement of entanglement refers to the task of extracting entanglement from an
entanglement resource via local operations and without communication while perturbing the …

Relativistic Quantum Fields Are Universal Entanglement Embezzlers

L van Luijk, A Stottmeister, RF Werner, H Wilming - Physical Review Letters, 2024 - APS
Embezzlement of entanglement refers to the counterintuitive possibility of extracting
entangled quantum states from a reference state of an auxiliary system (the “embezzler”) via …
