NIST researchers are developing a quantum network testbed to connect remote quantum nodes using optical links. The project aims to create a network of superconducting quantum computers connected by remote microwave entanglement, with a focus on creating telecom-connected quantum repeaters using neutral atom-based repeaters.
The team is working on several key components:
1. Two-mode squeezed states as a quantum resource
2. Microwave-to-optical transducers with world-leading performance
3. Quantum devices for telecom photon interfacing
4. Entangled-photon sources and single-photon detectors
The project has reached Technology Readiness Level 3-4 and has published notable research in Physical Review Applied and Physical Review Letters. The ultimate goal is to create a scalable quantum network infrastructure for regional, national, and global quantum communication.
