SUMMARY:Algebraic Graph Theory Seminar - Chris Godsil
CLASS:PUBLIC
DESCRIPTION:TITLE: Laplacian States\n\nSpeaker:\n Chris Godsil\n\nAffiliat
 ion:\n University of Waterloo\n\nZoom:\n Conatact Sabrina Lato\n\nABSTRACT
 :\n\nIt is customary to assume that the initial state of a continuous\nqua
 ntum walk on a graph $X$ is a vertex. However the Laplacian matrix\nof a g
 raph with vertex set $V(X)$ is positive semidefinite\, and can be\nscaled 
 to produce a density matrix\, and so provides an initial state\nfor a walk
  on $X$.
