Abstract

A simple, explicit boolean function on 2n input bits is presented that is 
computable by errorfree quantum read-once branching programs of size 
O(n^3), while each classical randomized read-once branching program 
and each quantum OBDD for this function with bounded two-sided error 
requires size 2^{omega(n)}.
