SUMMARY:Tutte Colloquium | Jake Doliskani\, Quantum Money: From Wiesner to\
 nStandard Assumptions
CLASS:PUBLIC
DESCRIPTION:SPEAKER:\n Jake Doliskani\n\nAFFILIATION:\n McMaster University
  \n\nLOCATION:\n MC 5501\n\nABSTRACT: Quantum money is one of the earlies
 t ideas in quantum\ncryptography: a banknote is represented by a quantum s
 tate that cannot\nsimply be copied. Wiesner’s original proposal required
  the bank to\nverify every transaction\, motivating the notion of public-k
 ey quantum\nmoney\, where anyone can verify a banknote while only the bank
  can\ncreate new ones.\n\nIn this talk\, I will trace the story of quantum
  money from Wiesner’s\nscheme\, through the hidden-subspace construction
  of Aaronson and\nChristiano\, to Zhandry’s recent construction from abe
 lian group\nactions. I will discuss why previous proposals were either bro
 ken or\nrelied on non-standard assumptions\, and then present recent work\
 nshowing that Zhandry’s construction can be based\, in the generic\ngrou
 p-action model\, on the standard group-action discrete logarithm\nassumpti
 on. I will conclude with the main idea behind the security\nproof.
