DESCRIPTION:Title: <a href="https://researchseminars.org/talk/3cqfs/38/">E
 xact measurement schemes for local observables and the preparation of phys
 ical local product states</a>\nby Chris Fewster (University of York) as pa
 rt of Tricontinental Quantum Fundamentals Seminar\n\n\nAbstract\nThis talk
  describes further developments in the framework for measurement in quantu
 m field theory introduced by myself and Verch [<a href="https://link.sprin
 ger.com/article/10.1007/s00220-020-03800-6" target="_blank">Commun. Math. 
 Phys. 378 (2020) 851-889</a> <a href="https://arxiv.org/abs/1810.06512" ta
 rget="_blank">arXiv:1810.06512</a>]. In particular\, it will be shown in a
  class of theories that any local observable can be measured\, and that tw
 o observers in spacelike separated laboratories can independently prepare 
 desired physical states\, which amounts to a constructive proof of the exi
 stence of physical local product states. I will aim to introduce the relev
 ant background.\n
