SUMMARY:Analysis Seminar
CLASS:PUBLIC
DESCRIPTION:JENNIFER ZHU\, UNIVERSITY OF WATERLOO\n\n_Morphisms of Quantum 
 Confusability Graphs_\n\nIt would be unrealistic to have an information ch
 annel — quantum or\nclassical — that always sends information with abs
 olute accuracy\;\nthat is\, we must expect a channel to have noise. In 195
 6\, Shannon\nintroduced the notion of zero-error capacity of a noisy (clas
 sical)\nchannel using the confusability graph of this channel. In 2010\, D
 uan\,\nSeverini\, and Winter developed the analogous notion (quantum\nconf
 usability graphs) for quantum channels and show that one can\nrecover vari
 ous types of zero-error capacities of quantum channels. In\nthe first half
  of this talk\, we will see how these quantum\nconfusability graphs are de
 rived and how they subsume Shannon's notion\nof classical confusability gr
 aphs.\n\nQNC 1201
