Two-dimensional network of atomtronic qubits

Abstract

Through a combination of laser beams, we engineer a 2D optical lattice of Mexican hat potentials able to host atoms in its ring-shaped wells. When tunneling can be ignored (at high laser intensities), we show that a well-de ned qubit can be associated with the states of the atoms trapped in each of the rings. Each of these two-level systems can be manipulated by a suitable con guration of Raman laser beams imprinting a synthetic ux onto each Mexican hat cell of the lattice. Overall, we believe that the system has the potential to form a scalable architecture for atomtronic ux qubits.
