Briefings

Cisco released two research prototypes in October 2026 to coordinate quantum networks, enabling applications to request entanglement without manually configuring hardware. The Quantum Network Controller manages hardware and schedules connections, while the Network-Aware Quantum Compiler divides computing tasks among processors. In a New York City test, the system coordinated equipment from multiple vendors over 11 miles of fiber, achieving greater than 99% polarization fidelity at room temperature. The service model, Entanglement-as-a-Service, allows applications to specify outcomes like fidelity and timing while the network handles resource allocation and timing coordination.

Key points

• Cisco's Quantum Network Controller manages hardware and schedules connections, while the Network-Aware Quantum Compiler divides computing tasks among processors.
• In a New York City test, the system coordinated equipment from multiple vendors over 11 miles of fiber, achieving greater than 99% polarization fidelity at room temperature.

Context and limitations

Cisco describes both systems as research prototypes; the announcement does not establish that a large network of connected quantum processors is ready for commercial use. The February 2026 deployment mentioned is evidence of coordination capability rather than proof of a fully connected network of 1,000 nodes.
