SUMMARY:Embezzlement of entanglement\, quantum fields and the classificatio
 n of\nvon Neumann algebras
CLASS:PUBLIC
DESCRIPTION:CS/MATH SEMINAR - LAURITZ VAN LUIJK\, LEIBNIZ UNIVERSITÄT HANN
 OVER\n\nQuantum-Nano Centre\, 200 University Ave West\, Room QNC 1201 + ZO
 OM\nWaterloo\, ON CA N2L 3G1\n\nEmbezzlement refers to the counterintuitiv
 e possibility of extracting\nentangled quantum states from a reference sta
 te of an auxiliary system\n(the \"embezzler\") via local quantum operation
 s while hardly perturbing\nthe reference. I will explain a deep connection
  between this\noperational task and the mathematical classification of vo
 n Neumann\nalgebras.\n\nThis result implies that relativistic quantum fiel
 ds are universal\nembezzlers: Any entangled state of any dimension can be 
 embezzled from\nthem with arbitrary precision. In particular\, this provid
 es an\noperational characterization of the infinite amount of entanglement
 \npresent in the vacuum state of relativistic quantum field theories and\n
 explains the classic result that the vacuum maximally violates Bell's\nine
 qualities: Alice and Bob can simply embezzle a maximally entangled\nqubit 
 pair and perform a Bell measurement.\n\nThe talk is based on joined work w
 ith A Stottmeister\, RF Werner\, and H\nWilming (see arXiv:2401.07292\n[h
 ttps://arxiv.org/abs/2401.07292]\, arXiv:2401.07299\n[https://arxiv.org/a
 bs/2401.07299]).
