Abstract
A large class of topological orders can be understood and classified using the string-net condensation picture. These topological orders can be characterized by a set of data . We describe a way to detect this kind of topological order using only the ground state wave function. The method involves computing a quantity called the “topological entropy” which directly measures the total quantum dimension .
