What it does. Where it fits.
Atom-based entangled-photon sources and active polarization compensation for optical-fiber networks.
Who should look closer
Telecom operators and quantum-network laboratories building field testbeds or studying links between quantum devices.
QubitWire’s editorial assessment of practical fit.Commercial networking hardware
Discuss Carina equipment and deployment requirements with Qunnect. Deutsche Telekom confirms commercially available hardware was used in its field trial.
Check the current access route ↗What has been demonstrated
Deutsche Telekom reports 90% average teleportation fidelity over 30 km of Berlin fiber in January 2026, alongside classical traffic. A separate preprint demonstrates entanglement swapping over 17.6 km of deployed New York fiber.
What remains unresolved
These experiments establish networking building blocks, not general-purpose distributed computing. The New York experiment uses superconducting detectors at its hub; room-temperature sources do not make the full system cryogen-free.
The next question to watch
How do fidelity, usable event rate and uptime hold up as field networks add nodes and integrate quantum memories or processors?
A research question, not a promised milestone.QubitWire coverage

Operator confirms January field trial using commercially available Qunnect hardware: 30 km fiber, 90% average teleportation fidelity and 95% peak, alongside classical traffic.
- High-rate Scalable Entanglement Swapping Between Remote Entanglement Sources on Deployed New York City Fibers ↗Organization-originated source · 17 Feb 2026
Public preprint, revised 2 March 2026, describes warm-vapor entanglement sources and swapping maintained over 17.6 km deployed fiber, with room-temperature spoke detectors and superconducting detectors at the hub.
- Qunnect and Cisco demonstrate metro-scale entanglement swapping over commercial fiber ↗Organization-originated source · 18 Feb 2026
Company reports Carina hardware integrated with Cisco orchestration; rates are 1.7 million pairs/hour locally versus 5,400 pairs/hour over deployed fiber, which must remain separate.
