We propose a quantum cellular automata composed of nanostructured mesoscopic superconducting squares, where the logic states are defined by two trapped vortices in a 2×2 blind hole matrix. We present the functioning logic gate based on this fluxonic cellular automata, where the logic operations are verified through theoretical simulations within the Ginzburg-Landau formalism. The input signals are defined using the vortex interaction with current loops placed on top of the two diagonal blind holes of the input cell. The readout technology may be chosen from a large variety of modern vortex imaging methods, transport, and local density of states measurements.
