Abstract

We describe a quantum PAC learning algorithm for DNF formulae under the uniform distribution with a query complexity of 脮(s3/驴 + s2/驴2), where s is the size of DNF formula and 驴 is the PAC error accuracy1. If s and 1/驴 are comparable, this gives a modest improvement over a previously known classical query complexity of 脮(ns2/驴2). We also show a lower bound of 驴(s log n/n) on the query complexity of any quantum PAC algorithm for learning a DNF of size s with n inputs under the uniform distribution.
