  Quantum annealing aims at solving optimization problems efficiently by
preparing the ground state of an Ising spin-Hamiltonian quantum mechanically. A
prerequisite of building a quantum annealer is the implementation of
programmable long-range two-, three- or multi-spin Ising interactions. We
discuss an architecture, where the required spin interactions are implemented
via two-port, or in general multi-port quantum Ising wires connecting the spins
of interest. This quantum annealing architecture of spins connected by Ising
quantum wires can be realized by exploiting the three dimensional (3D)
character of atomic platforms, including atoms in optical lattices and Rydberg
tweezer arrays. The realization only requires engineering on-site terms and
two-body interactions between nearest neighboring qubits. The locally coupled
spin model on a 3D cubic lattice is sufficient to effectively produce arbitrary
all-to-all coupled Ising Hamiltonians. We illustrate the approach for few spin
devices solving Max-Cut and prime factorization problems, and discuss the
potential scaling to large atom based systems.
