We present a quantum algorithm for finite domain constraint solving, where the constraints have arity 2. It is complete and runs in O((d/2) n/2 ) time, where d is size of the domain of the variables and n the number of variables. For the case of d = 3 we provide a method to obtain an upper time bound of O(8 n/8 ) ≃ O(1.2968 n ). Also for d = 5 the upper bound has been improved. Using this method in a slightly different way we can decide 3-colourability in O(1.2185 n ) time.
