Cisco Demonstrates Metropolitan Quantum Network Architecture Breakthrough
Summary
Cisco demonstrated 5,400 entangled pairs per hour over 17.6km standard fiber in urban environment, validating software-defined quantum network architecture. The solution uses control software for picosecond synchronization with hub-spoke design to reduce scaling costs, proving quantum networks can leverage existing telecom infrastructure.
Key Takeaways
Cisco and partners demonstrated metropolitan entangled quantum network over 17.6km standard telecom fiber between Manhattan and Brooklyn. Achieved over 5,400 entangled pairs per hour with >99% polarization fidelity, performance improved by 3-4 orders of magnitude over lab attempts.
Core technology uses software-hardware separation architecture. Cisco's control software enables picosecond synchronization via White Rabbit protocol, automating entanglement distribution across three geographic nodes. Employs hub-spoke design with core cryogenic equipment at hub and room-temperature hardware at edges.
