In the standard Aharonov-Bohm effect, the magnetic flux involved is taken to be classical and with a well-defined value. Here, we consider what happens if the magnetic flux is in a quantum mechanical superposition of two values. We find that the interference pattern in the Aharonov-Bohm effect contains information about the nature of the superposition, allowing information about the state of the flux to be extracted without disturbing it. The approach is novel in that the information is obtained by a non-local operation involving the vector potential without transfer of energy or momentum. The information is also not obtained via a single interaction of a charged particle with the vector potential, but rather by the accumulated interactions of many particles which form the interference pattern. Suggestions are made as to how an experiment to test this effect could be done using superposed currents in a superconducting ring which has already been experimentally realized. Broader implications of the result are also discussed.
