SUMMARY:What dimension is necessary for quantum correlations in the commut
 ing operator framework? - Lauritz van Luijk (Leibniz University Hannover)
DTSTART:20231026T131500Z

CONTACT:Subhayan Roy Moulik
DESCRIPTION:I will discuss correlation experiments in settings where syste
 ms are described in terms of their observable algebras\, as is often the c
 ase in QFTs or statistical mechanics with infinite degrees of freedom. Her
 e\, inequivalent ways of model bipartite systems exist (known as the “te
 nsor product model” and the more general “commuting operator framework
 ”).\nTo study the question in the title\, we generalise the concept of t
 he Schmidt rank to bipartite states in the commuting operator framework. I
  will explain operational and algebraical definitions of the Schmidt rank.
  If time permits I will discuss the example of ground states on infinite 1
 d spin chains which are viewed as bipartite state for the left and right h
 alf chains.\n
