  We present the design of a chiral photonic quantum link, where distant atoms
interact by exchanging photons propagating in a single direction in free-space.
This is achieved by coupling each atom in a laser-assisted process to an atomic
array acting as a quantum phased-array antenna. This provides a basic building
block for quantum networks in free space, i.e. without requiring cavities or
nanostructures, which we illustrate with high-fidelity quantum state transfer
protocols. Our setup can be implemented with neutral atoms using
Rydberg-dressed interactions.
