Abstract

We consider a mesoscopic square superconductor with 2×2 blind holes in the presence of a homogeneous magnetic field. Under suitable conditions a diagonal L=2 state is realized and the system reduces to double degenerate states with different flux configurations, which can be considered as logic states. We show the possibility of manipulation of these states by circulating currents in a loop near the superconductor.
