  The realization of a quantum network node of matter-based qubits compatible
with telecom-band operation and large-scale quantum information processing is
an outstanding challenge that has limited the potential of elementary quantum
networks. We propose a platform for interfacing quantum processors comprising
neutral atom arrays with telecom-band photons in a multiplexed network
architecture. The use of a large atom array instead of a single atom mitigates
the deleterious effects of two-way communication and improves the entanglement
rate between two nodes by nearly two orders of magnitude. Further, this system
simultaneously provides the ability to perform high-fidelity deterministic
gates and readout within each node, opening the door to quantum repeater and
purification protocols to enhance the length and fidelity of the network,
respectively. Using intermediate nodes as quantum repeaters, we demonstrate the
feasibility of entanglement distribution over approximately 1500 km based on
realistic assumptions, providing a blueprint for a transcontinental network.
Finally, we demonstrate that our platform can distribute approximately 25 Bell
pairs over metropolitan distances, which could serve as the backbone of a
distributed fault-tolerant quantum computer.
