SUMMARY:Tutte Colloquium - Daniel Grier
CLASS:PUBLIC
DESCRIPTION:Zoom (for information email emma.watson@uwaterloo.ca) \n\nTITL
 E: Permanent Hardness from Linear Optics\n\nSpeaker:\n Daniel Grier\n\nAf
 filiation:\n University of Waterloo\n\nLocation:\n Online (Zoom)\n\nABSTRA
 CT:\n\nOne of the great accomplishments in complexity theory was Valiant's
 \n1979 proof that the permanent of a matrix is #P-hard to compute. \nSubs
 equent work simplified Valiant's ideas and even began to recast\nthem as p
 roblems in quantum computing.  In 2011\, this culminated in a\nstriking p
 roof by Aaronson\, based solely on quantum linear optics\, of\nthe #P-hard
 ness of the permanent.
