How to demonstrate quantum locality of the Aharonov-Bohm effect in superconducting devices?

It is generally believed that the locality principle is not fulfilled in the quantum mechanical treatment of electromagnetic interaction, which is highlighted in the Aharonov-Bohm effect. I will argue that this standard viewpoint draws some inconsistency with the duality of the Aharonov-Bohm and the Aharonov-Casher effects.
Accordingly, we have developed an alternative "local" theory, on the basis of Lorentz-covariant field interaction.
Aharonov-Bohm interference without forming a closed path is predicted in this approach, and I will discuss how it can be realized in superconducting devices.
