Exponential-Time Quantum Algorithm for Graph Coloring Problem
Kazuya Shimizu, Ryuhei Mori (TiTech)
Abstract (in Japanese) (See Japanese page) 
(in English) In this work, we show an exponential-time quantum algorithm for the graph k-coloring problem, which is one of the well-known NP-complete problem. The fastest known classical algorithm for the graph k-coloring problem requires O^∗ (2^n) time for k >= 5. For any k <= 24, our quantum algorithm solves the graph k-coloring problem with time O^∗ ((2 − ϵ)^n).
