摘要：

We argue that frustrated Josephson junction arrays may support a topologically ordered superconducting ground state, characterized by a non-trivial groundstate degeneracy on the torus. This superconducting quantum fluid provides an explicit example of a system in which superconductivity arises from a topological mechanism rather than from the usual Landau-Ginzburg mechanism.
