CONTACT:Sergii Strelchuk
DESCRIPTION:In this talk I will give an introduction to randomized benchma
 rking\, a standard experimental technique in quantum computing. I will rev
 iew the reasons for its existence and the functioning of its standard 'Cli
 fford group' version from a representation theoretical angle. Using this r
 epresentation theory perspective one can see that randomized benchmarking 
 can be generalized to arbitrary finite groups. I will show how to do this 
 in a principled manner and discuss some issues that appear. Finally\, if t
 here is time\, I will try to give a hint of how the powerful machinery of 
 harmonic analysis can be applied to guarantee the correct functioning of r
 andomized benchmarking under very broad experimental conditions.
