SUMMARY:The Impossibility of Efficient Quantum Weak Coin-Flipping
CLASS:PUBLIC
DESCRIPTION:Summary \n\nCOLLOQUIUM FEATURING CARL ALEXANDER MILLER - QUICS 
 AND NIST\n\nHow can two parties carry out a fair coin flip across a noisel
 ess\nquantum channel? In 2007\, Carlos Mochon proved a tantalizing result:
 \nhe showed that fair quantum coin flipping is possible in principle\,\nbu
 t he used a protocol that required a huge (exponential) number of\ncommuni
 cation rounds. In the twelve years since\, despite some\ncontinued deep th
 eoretical work on the problem\, no improvements to the\nefficiency of Moch
 on's protocol have been made.\n
