Qunnect and Cisco’s Quantum Leap in NYC

In an exciting development for quantum networking, Qunnect and Cisco have successfully demonstrated advanced entanglement swapping on the GothamQ network in New York City. This cutting-edge network, utilizing a hub-and-spoke model, connects entanglement sources in Brooklyn to a central hub at 60 Hudson Street in Manhattan. The setup enables more efficient entangled state swapping, a key step for quantum communication.

The connection comprises 17.6 kilometers of telecom-grade fiber beneath NYC’s lively streets, presenting challenges and potential interference. Qunnect’s Carina technology plays a central role, featuring advanced quantum networking components. At the nodes, equipment operates at room temperature with SPAD detectors, whereas the hub requires SNSPDs, demanding cryogenic conditions. Cisco’s software oversees the entire operation, ensuring seamless coordination, essential for maintaining high-quality operations.

Breaking Boundaries with Quantum Entanglement

This pioneering collaboration achieved remarkable rates: over 1.7 million entangled pairs per hour locally, and 5,400 pairs per hour over fiber, with polarization fidelity surpassing 99%. These advancements are vital as quantum data centers connect multiple quantum computers for more extensive processing. The project highlights the potential of long-range networks using quantum repeaters.

Qunnect and Cisco’s continuous work in quantum networking promises to expand the current technological horizons. For those keen on delving deeper, consider exploring Qunnect’s GothamQ network details or attending their upcoming webinar. Stay informed about this promising venture as quantum networking continues to evolve.
