Titolo: Quantum invariants for graph isomorphism
Abstract: Since McKay presented his Nauty algorithm in 1981 to characterize
graph isomorphism until the last proposal by Babai in 2015, a huge
effort has been devoted to the graph isomorphism problem together with
an improvement on their complexities. This problem is assumed to
belong to neither P nor NP-Complete Computational Complexity classes.
Maybe the most efficient deterministic algorithm on practice currently
available is Traces algorithm proposed by McKay & Piperno in 2014.
Quantum computing is facing this problem in an almost disruptive and
very interesting perspective...
