DESCRIPTION:Title: <a href="https://researchseminars.org/talk/PUHET/8/">Qu
 antum error correction and large N</a>\nby Alexey Milekhin (Princeton) as 
 part of Princeton HET seminar\n\n\nAbstract\nIn recent years quantum error
  correction (QEC) has become an important part of AdS/CFT. Unfortunately\,
  there are no field-theoretic arguments about why QEC holds in known holog
 raphic systems. The purpose of this talk is to fill this gap by studying t
 he error correcting properties of the fermionic sector of various large N 
 theories. Specifically we examine SU(N) matrix quantum mechanics and 3-ran
 k tensor O(N)^3 theories. Both of these theories contain large gauge group
 s. We argue that gauge singlet states indeed form a quantum error correcti
 ng code. Our considerations are based purely on large N analysis and do no
 t appeal to a particular form of Hamiltonian or holography.\n
