Telecom Quantum Network Node via Atom-Nanophotonic Coupling

We propose neutral atoms coupled to telecom nanophotonic cavities as quantum network nodes. Our novel protocol for generating atom-telecom photon entanglement enables a scalable network architecture featuring identical qubits and direct telecom operation.

Nanophotonic quantum network node with neutral atoms and an integrated telecom interface

The realization of a long-distance, distributed quantum network based on quantum memory nodes that are linked by photonic channels remains an outstanding challenge. We propose a quantum network node based on neutral alkali atoms coupled to nanophotonic crystal cavities that combines a long-lived memory qubit with a photonic interface at the...
